1. The document provides information about heredity, variation, Mendel's experiments with pea plants, evolution, and human evolution.
2. Mendel conducted experiments with pea plants involving monohybrid and dihybrid crosses to study patterns of inheritance. His experiments showed dominant and recessive traits are inherited in predictable ratios.
3. Evolution occurs through natural selection acting on genetic variations over many generations, leading to the formation of new species. Evidence for evolution comes from homologous and analogous structures as well as fossils.
The document discusses heredity and variation in organisms. It defines heredity as the transmission of traits from parents to offspring. Variation refers to the differences in traits among individuals of a species. The document lists several examples of variations in humans such as eye color, hair color, height etc. It also discusses Gregor Mendel's experiments with pea plants which laid the foundations for modern genetics through his principles of inheritance, including dominant and recessive genes.
Plants are essential sources of food for animals and people. They produce their own food through photosynthesis, and their parts like leaves, roots, seeds, and stems are used as vegetables in the human diet. Plants also produce oxygen, recycle nutrients in the environment, and have many other uses like providing wood, fibers, oils, ornaments, and medicine. Without plants, major problems would occur as they are key to sustaining life on Earth.

- Heredity is the transfer of traits from parents to offspring. Variations among individuals of the same species exist.
- Mendel conducted experiments with pea plants and determined rules for inheritance. He found traits are inherited as discrete units (now known as genes) and that dominant traits mask recessive traits in the first filial generation.
- Mendel's laws are: 1) Law of dominance, 2) Law of segregation, 3) Law of independent assortment. These laws explain the patterns of inheritance he observed through his experiments.

THE LIVING ORGANISMS -CHARACTERISTICS AND HABITATS-3 CBSE-V CHAPTER-9BIOLOGY TEACHER
Organisms
An organism is simply defined as any living thing, ranging from microscopic bacteria to large elephants and everything in between.
Different types of plants and animals are found in different areas.
E.g. deserts have camel and cacti as plants. Beaches show coconut trees and crabs. Fishes and other marine animals inhabit the sea
LifeLines of the Indian Economy - RoadwaysShivangi Singh
India has one of the largest road networks in the world, totaling about 2.3 million kilometers. Roads are considered more flexible and economical than railways, as they can reach more areas by traversing slopes, hills, forests, and streams. Road transportation allows for door-to-door delivery of goods and people over short distances in a flexible manner. India classifies its roads as: Golden Quadrilateral super highways linking major cities launched by NHAI; National Highways linking parts of India managed by CPWD; State Highways connecting state capitals to district headquarters managed by PWD; District Roads connecting district headquarters to other places managed by Zila Parishad; and other local roads connecting rural areas.
Plants are vital to all life on Earth by providing food, water, oxygen, habitat, and medicine. They are directly or indirectly the source of all human food and have been used for food throughout history. Plants also regulate the water cycle, help distribute and purify water, and move water from soil to atmosphere through transpiration. Additionally, they produce oxygen through photosynthesis and make up the backbone of all habitats by providing food and shelter for other wildlife. Around one-quarter of prescription drugs come from plants or are plant-based derivatives, and four out of five people rely on plants for primary health care.
This document discusses trees, deforestation, fossil fuels, and conservation. It covers:
1) The importance of trees for habitat, oxygen production, and products like timber.
2) Causes of deforestation like wood usage, grazing, and urbanization and its effects like soil erosion, habitat destruction, and climate change.
3) Consequences of overextracting fossil fuels like resource depletion, air pollution, and threats to organisms.
4) Ways to conserve forests like afforestation and awareness programs, and fossil fuels through renewable energy sources like wind, hydroelectric, nuclear, and solar power.
Resources can be classified as natural, human-made, or human. Natural resources come from nature and include biotic resources like plants and animals as well as abiotic resources like air and water. They can also be classified as renewable like solar energy or non-renewable like fossil fuels. Human-made resources are those created through human technology and skill while human resources refers to people. It is important to conserve resources through sustainable use and development to meet current needs without compromising the ability of future generations to meet their needs.
This document provides information about carbon and its compounds. It discusses electron dot structures of various molecules like H2, O2, ethane and unsaturated hydrocarbons. It also describes cyclic/closed chain hydrocarbons and aromatic hydrocarbons like benzene. The document outlines IUPAC naming rules for hydrocarbons and different formula types. It provides examples of alkenes, alkynes and their naming conventions. Key differences between properties of covalent and ionic compounds are highlighted.
This document provides information about reproduction in organisms. It discusses that reproduction allows organisms to produce new individuals of the same species and is necessary for survival and population growth. During reproduction, DNA is copied but not identically, allowing for variation between offspring. This variation is important for adaptation to environmental changes and evolution of new species. The document also describes different types of reproduction like asexual reproduction, sexual reproduction, and modes of asexual reproduction like fission, budding, regeneration etc. It further discusses sexual reproduction in flowering plants and human beings.

The document discusses several prominent environmental activists from India, including Sugathakumari, Medha Patkar, Sunderlal Bahuguna, Maneka Gandhi, and Arundhati Roy. It highlights their key causes and accomplishments, such as Sugathakumari's involvement in the "Save Silent Valley" and "save kurinji" campaigns, and Medha Patkar leading the "Narmada Bachao Andolan" movement. The document also briefly profiles international activists like Angelina Jolie and her donations to environmental causes, and Indian actor John Abraham's work with wildlife protection organizations.
The document discusses key concepts in chemistry including atoms, molecules, ions, and moles. It introduces important historical figures like Antoine Lavoisier, John Dalton, and Amedeo Avogadro. It defines atoms as the smallest particles that make up elements and participate in chemical reactions. Molecules are groups of atoms bonded together. Ions are atoms or groups of atoms with a positive or negative charge. The mole concept relates the mass of a substance to its number of particles or molecules.
Natural resources and types of natural resourcesDEVIKA S INDU
Natural resources can be classified in several ways based on their origin, abundance, renewability, and development stage. Biotic resources like wildlife originate from living organisms, while abiotic resources like metals are non-living. Resources are also exhaustible if they can be depleted, like fossil fuels, or inexhaustible if replenished like solar energy. Renewable resources regenerate naturally, unlike non-renewable resources. Potential resources have yet to be developed, whereas actual resources are currently being used. Conservation of natural resources is important as most are finite or non-renewable.
Resources are all elements of the environment that satisfy human needs. They include natural resources like soil, rocks, minerals, as well as human-made resources like buildings and bridges. Natural resources can be classified as actual or potential, biotic or abiotic, renewable or non-renewable, and ubiquitous or localized based on their origin, stock, distribution, and development level. While natural resources occur naturally, human-made resources are created through human knowledge, skills, and technology to further utilize natural substances. People themselves are also an important human resource.

The document discusses three maritime activities in the UAE:
1) Fishing - The UAE has traditionally depended on fishing and the government has modernized the industry.
2) Pearl diving - This was historically an important occupation in Dubai and the UAE but has been replaced by pearl farms.
3) Ship building - The UAE population was known for ship building and the government has developed infrastructure to become a top global destination for ship building.
1. Reproduction is the process by which living organisms produce new individuals of the same species through asexual or sexual reproduction. It is necessary for survival and increasing population size.
2. Asexual reproduction involves a single parent and methods include fission, budding, regeneration, fragmentation, and spore formation. Sexual reproduction involves two parents fusing male and female gametes.
3. In humans, sexual reproduction involves the male and female reproductive systems. Fertilization occurs when sperm fuse with eggs in the fallopian tubes, and the embryo implants in the uterus for gestation.
11. Transportation in Animals and Plants by Dilip Kumar ChandraDilip Kumar Chandra
The document discusses transport systems in animals and plants. It describes how circulatory systems transport oxygen, nutrients, wastes, and other materials throughout animal bodies using blood, blood vessels and the heart. The circulatory system consists of arteries, veins and capillaries. Arteries carry oxygen-rich blood away from the heart while veins carry deoxygenated blood back to the heart. Transport of water and nutrients in plants occurs through xylem tissue while transport of food occurs through phloem tissue. Transpiration through leaves generates suction that transports water through xylem vessels in plants.
The environmental movement aims to promote sustainability, reuse, source reduction, and innovation to protect the planet. Key events included Rachel Carson's 1962 book Silent Spring about pesticides, the first Earth Day in 1970, and the establishment of the EPA. Important leaders were Rachel Carson, Al Gore, Gifford Pinchot, John Muir, and Theodore Roosevelt. The movement has led to recycling, reduced pollution, cleaner air and water, and a focus on green technology and energy, though these solutions also have costs and limitations. Overall the environmental movement has significantly impacted economies, lifestyles, laws, and how people view protecting the environment.
The document summarizes the history and impact of Earth Day from its founding in 1970 to present day. It describes how Earth Day founder Gaylord Nelson was inspired by the anti-war movement to bring environmental issues to national attention. The first Earth Day in 1970 engaged 20 million Americans and helped pass landmark environmental legislation. Subsequent Earth Days in 1990, 2000, and 2010 grew the movement globally and addressed new threats like climate change. Earth Day now engages over 1 billion people worldwide, making it the largest secular event in the world focused on environmental action and protection.

The Oxford lexicon characterizes Environment as the environment or conditions in which a man, creature or plant lives or works . The earth has happened to extraordinary worry in the previous decade. Ecological topics, for example, change in atmosphere, loss of biodiversity, contamination, an Earth wide temperature boost, and maintainable improvement, etc, have possessed a noteworthy space in the media channels and the administration strategies. We have been contaminating our planet, draining its assets, and amassing a huge amount of non biodegradable waste. Now of time, although private enterprise and industrialization have made the most astounding material ways of life, yet the procedure has exhausted the nature of living as it has, in the meantime expanded the rate at which we dirty, drain, and make squander. As previous Vice President Al Gore deduced in his book Earth to be determined, Human development is currently the prevailing reason for change in the worldwide condition. The natural outcomes of worldwide environmental change have turned out to be increasingly evident and of more noteworthy open concern. Endeavours to spare the earth can be followed back to as ahead of schedule as the 1900s yet not until the beginning of 21st century. Individuals attempted endeavors to work overall and battle condition exhaustion. Whats more, for a similar reason, Environmentalism has advanced as a progressively concrete and required idea in the pop culture. Little yet noteworthy endeavors have been taken to spare our condition.

The document summarizes key topics in environmental science, including:
- The debate around building a dam in Hetch Hetchy valley of Yosemite National Park to provide water for San Francisco.
- Major issues like resource depletion, pollution, loss of biodiversity, and different approaches to environmental ethics between anthropocentrism and ecocentrism.
- The development of environmentalism from conservation to modern activism in response to events like oil spills and toxic pollution.
The document summarizes the history and impact of Earth Day from its founding in 1970 to present day. It describes how Earth Day founder Gaylord Nelson was inspired by the anti-war movement to bring environmental issues to national attention. The first Earth Day in 1970 engaged 20 million Americans and helped pass major environmental legislation. Subsequent Earth Days in 1990, 2000, and 2010 expanded the scope internationally and drew hundreds of millions of participants to address climate change and promote environmental causes. Earth Day has grown to be the largest secular event worldwide, observed by over a billion people annually.
The Nature Quiz organised by Jalpaiguri Zilla School and conducted by Mrinmay Mandal and Jyotiraditya Chanda, students of the same school of class XII.
The document summarizes key concepts in environmental science through a series of sections:
1. It discusses the debate around building a dam in Hetch Hetchy valley in Yosemite National Park to provide water for San Francisco. This was one of the first major debates between anthropocentric and ecocentric views.
2. It then covers broader environmental topics like resource depletion, pollution, loss of biodiversity, and environmental ethics. Developed and developing countries are also compared in their impact and approach to the environment.
3. Sustainability and the closed system of the Earth are discussed as major challenges given the planet's limited resources and growing population. Meeting needs today without compromising the future is emphasized
Environmental science is the study of the interaction of humans with the natural environment.
The environment includes all conditions that surround living organisms:
Climate
Air and water quality
Soil and landforms
Presence of other living organisms
History of environmental planning and management since mid 20th centuryGeofrey Yator
Environmental planning and management began in the mid-20th century due to increasing environmental degradation from industrialization and population growth. Several major pollution events in the 1940s-1960s caused health issues and brought environmental problems into focus. In 1972 the UN held its first global environmental convention, outlining 26 principles including that humans impact and rely on the environment, and international cooperation is needed to protect the environment for human well-being. Numerous national environmental laws were subsequently passed through the 1970s-1990s to regulate air, water, and hazardous waste pollution.
Earth Day is celebrated annually on April 22nd to raise global awareness about environmental protection. It was founded in 1970 by US Senator Gaylord Nelson as a teach-in on environmental issues in response to increasing pollution. Over 20 million Americans demonstrated on the first Earth Day, bringing national attention to issues like oil spills, industrial pollution, and the impacts of waste on natural areas and wildlife. This mobilization helped pass new environmental laws in the US and inspired an annual global celebration of environmental stewardship.
The document provides information about Earth Day and the history of the environmental movement. It discusses how Earth Day originated in 1970 to raise awareness about pollution and environmental protection. The first Earth Day in 1970 helped put environmental issues on the national agenda in the US and gave voice to the emerging public concern about the state of the planet. Rachel Carson's book Silent Spring, which documented the effects of pollution and pesticides, was influential in raising environmental consciousness before the first Earth Day.
Introduction to Environmental Science.pptxkriztianibaos3
The document discusses environmental issues related to resource use and sustainability. It begins by discussing the gold rush population boom in San Francisco and the 1906 earthquake and fire that damaged infrastructure. To address water issues, city planners sought to dam Hetch Hetchy valley in Yosemite National Park, igniting a debate between anthropocentric and ecocentric views. The document then covers various environmental topics like nonrenewable resources, pollution, biodiversity loss, and ethics. It examines tensions between short-term economic gains and long-term sustainability, and differences between developed and developing nations in standards of living and environmental impacts. Throughout, it emphasizes that human society and the environment are interlinked systems that must achieve balance to allow for continued
This is a PowerPoint Presentation on Earth Day. It shows all the major facts about the Earth Day. This is Original. I created it myself. It is best if it downloaded as an video to see its transitions and animations. No helps from Search Engines. Hope you all like it. Thank You
The document discusses Earth Day, which is celebrated annually on April 22nd. It originated in 1970 in the US as an environmental teach-in organized by Senator Gaylord Nelson in response to environmental damage. Earth Day now involves events worldwide to support environmental protection and is coordinated globally. The document provides background on Earth Day's origins and growth, as well as facts about annual celebrations and themes over the years focused on issues like climate change, sustainability, and tree planting.
This document discusses several key topics in environmental science, including resource depletion, pollution, biodiversity loss, environmental ethics, and sustainability. It notes that while renewable resources can regrow within a human lifetime, nonrenewable resources like coal are finite and will eventually run out if usage is not reduced. It also explores how pollution from industry can spread globally and harm ecosystems far from the source. Developing countries often face more severe environmental problems due to lower regulations and protections. Achieving sustainability will require meeting human needs without compromising the environment for future generations on our limited planet.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
2. History of Environmentalism
When early hunter-gatherers realized how fire and hunting tools influenced their
surroundings, they likely became aware of our precarious relationship with our
habitat. Anthropologists have discovered evidence of human-caused animal
and plant extinctions dating back to 50,000 BCE, when there were only
approximately 200,000 Homo sapiens roaming the Earth. We can only
speculate on how these early humans reacted, but it appears that migration to
new habitats was a common response.
Environmental consciousness first occurs in the human record at least 5,000
years ago. In their hymns, Vedic sages celebrated the natural forests, Taoists
advocated that human life follow the rhythms of nature, and the Buddha taught
compassion for all sentient beings.
The Indus civilization at Mohenjo Darro (an ancient city in modern-day
Pakistan) recognized the consequences of pollution on human health five
thousand years ago and practiced waste management and sanitation. Plato
bemoaned in Greece when deforestation caused soil erosion, " All the richer
and softer parts have fallen away, and the mere skeleton of the land remains.”
Communities in China, India, and Peru recognized the dangers of soil erosion
and worked to prevent it through the use of terraces, crop rotation, and nutrient
recycling.
Hippocrates and Galen, Greek physicians, began to notice environmental
health issues such as acid poisoning in copper miners. The earliest extant
European treatise on human ecology is Hippocrates' book, De aere, aquis et
locis (Air, Waters, and Places).
Agriculture advancement increased human populations but also caused soil
erosion and insect infestations, resulting in devastating famines between 200
and 1200 CE. Due of pollution, King Edward I of England limited coal burning in
London in 1306. Naturalist and gardener John Evelyn claimed in the 17th
century that London resembled "the districts of Hell." These events sparked
Europe's first "renewable" energy boom, with governments beginning to
subsidize water and wind power.
3. History of Environmental Rights
The Bishnoi Hindus of Khejarli were maybe the first true environmental activists,
killed by the Maharaja of Jodhpur in 1720 for attempting to defend the forest he
cut to build himself a palace. The 18th century saw the emergence of modern
environmental rights. Following a yellow fever outbreak in Philadelphia, Benjamin
Franklin petitioned for waste management and the removal of tanneries for clean
air as a public "right" (ironically, on land stolen from Indigenous nations). Later,
American artist George Catlin recommended that Indigenous land be maintained
as a "natural right.”
At the same time, in the United Kingdom, Jeremy Benthu published An
Introduction to Moral Principles and Legislation, which advocated for the rights of
animals. Thomas Malthus produced his renowned essay warning that human
overpopulation will destroy the environment. Global warming was first recognized
200 years ago, when Jean Baptiste Fourier calculated that the Earth's
atmosphere stored heat like a greenhouse.
A few decades later, George Perkins Marsh wrote Man and Nature, which
criticizes humanity's indiscriminate "warfare" on nature, warning of climate
change, and emphasizing that "the world cannot afford to wait" - a cry that we still
hear today.
4. History of the Modern Sustainability Movement
To understand the modern sustainability movement, we must first understand what
“sustainability” even means. By definition (according to the U.S. Environmental Protection
Agency), sustainability is “Everything that we need for our survival and well-being depends,
either directly or indirectly, on our natural environment. To pursue sustainability is to create
and maintain the conditions under which humans and nature can exist in productive
harmony to support present and future generations.”
The sustainability movement can be traced back to the 19th century, a time when the
Industrial Revolution brought us great advancements in technology like modern cities,
railroads, and factories that relied on oil and coal for energy. Unfortunately, all of these
advancements came with the price of overpopulation, pollution, and disease.
A notable figure in the early beginnings of the sustainability movement is Theodore
Roosevelt. Becoming president of the United States in 1901, Roosevelt was well-known for
his devotion to nature and conservation. During the course of his presidency, Roosevelt
managed to create the United States Forest Service and founded 150 national forests, 81
national monuments, 51 federal bird reserves, 5 national parks, and 4 national game
reserves.
After World War II, the very first conservation conference was held by the United Nations in
1949. Hundreds of environmental from around the globe came together to discuss how to
conserve natural resources like land, water, wildlife, and energy. In 1955, the U.S.
Congress enacted the Air Pollution Act, which focused on researching the effects of air
pollution.
By 1970, the National Environmental Policy Act (NEPA) was established, requiring all
executive federal agencies to perform environmental assessments and release
environmental impact statements. This same year, we celebrated our very first “Earth Day”
on April 22nd. Along with NEPA, the United States started the Environmental Protection
Agency (EPA) and passed the Clean Air Act. In 1972, the Clean Water Act created by the
EPA was also passed. 1972 also marked the second conference held by the U.N. that was
created to discuss global issues concerning the environment, conservation, and
sustainability. This conference spurred the creation of the U.N. Environment Program
(UNEP).
By the 1990s, green brands started to gain popularity and traction. Businesses started using
“eco-friendly” as a selling point. By mid 2000s, the U.N. General Assembly published their
Sustainable Development Goals to be achieved by the year 2030. Many of the goals, like
“Goal #6: Clean Water and Sanitation” and “Goal #7: Affordable and Clean Energy,” are
focused on environmental sustainability issues.
5. History of Green Brands
In the early 1980s, many of the hippies of the 1960s who had fallen out in the
1970s were coming of age as entrepreneurs and business owners. Some of
today's most well-known green firms may trace their roots back to this time period,
including Whole Foods, Burt's Bees, Seventh Generation, Tom's of Maine, and
The Body Shop. All of these notable green firms were start-ups or blossoming
enterprises in the early 1980s, originating from the 1970s back-to-nature
movement. Tom's of Maine and Burt's Bees originated in rural regions, providing
natural products to clients who shared their values. Whole Foods is the result of
the combination of two natural food stores. Despite producing different products,
both Burt's Bees and Whole Foods had visionary leaders who founded their
companies because it was the right thing to do, rather than simply because there
was consumer or market demand. Although all of these businesses began as
niche brands, it didn't take long for them to establish a market for their
environmentally friendly products.
By the latter half of the 1980s, individuals who were more earth-conscious started
to become a large enough group that their influence was being noticed in markets
and manufacturing. In 1988, The Green Consumer Guide was published and sold
over 1 million copies. It was the first book of its kind to focus on eco-friendly
consumer choices. The end of the 1980s saw an explosion of new green products
from companies both large and small, as they were all trying to capitalize on the
new green niche in the market. In just one year, from 1989 to 1990, the number of
new green products on the market more than doubled. At the same time, many
popular brands were starting to come under fire for not being sustainable. For
example, people boycotted McDonald’s nonrecyclable packaging, causing them
to move to more sustainable paper-based packaging.
6. History of Eco-Friendly Cleaning Products
Green cleaning may appear to be a new trend, but it is actually not at all. While it has
definitely grown in popularity in recent years, its origins can be traced back to the
1960s. Prior to the 1960s, humans were very uninformed on the impact of cleaning
chemicals, as well as other pollutants, may have on the environment- including the
impact on the animals and humans who cohabitate this planet.
Many people link the modern environmental movement to biologist Rachel Carson's
1962 book, Silent Spring, which focused on the dangers of pesticides. The Santa
Barbara oil spill occurred in 1969, which engendered the passing of the National
Environmental Policy Act. By the 1970s, green products were really starting to gain
traction. Tom’s (now called Tom’s of Maine) introduced a phosphate-free laundry
detergent, making them one of the first cleaning product brands to focus on
environmental responsibility.
In 1988, the Green Consumer Guide was published, which as stated previously, sold
more than 1 million copies. In this same year, the company Seventh Generation was
founded, which is still one of the biggest names in green cleaning brands of the
modern day. In the following 2 years, the interest in green products continued to
flourish with more than 10% of products introduced in those 2 years being considered
green. In the 1990s, climate change became a popular topic. By the early 2000s,
sustainability had become more than a counterculture niche and had become
mainstream. Green brands that already existed became more popular during this time,
new green brands gained traction, and leading mainstream brands started introducing
eco-friendly product lines.
While most people use chemical cleaners to rid their houses of bacteria and germs,
natural alternatives can accomplish the job just as well. Cleaning may take a little
longer and require a little more elbow grease, but eco-friendly cleaning tools help you
fight bacteria without introducing harmful chemicals into your home or company. Indoor
air quality is very important to your health, so reducing the amount of chemicals you
inhale should be an integral part of your daily life.
Green cleaning may require a bit more effort on your part, but the advantages far
exceed the drawbacks. With so many goods and recipes accessible, the obstacles of
obtaining green cleaning products reduce. Finally, you should feel good about your
home and your health - green cleaning could be the solution.
7. History of Eco-Fashion
Eco fashion may be popular now, but there was only one type of fashion a few
decades ago (hint: it wasn’t eco-friendly). Unethical and unsustainable
methods of garment production have been harming the environment and the
companies that practice this also treat laborers unfairly. Some prominent fast
fashion companies were exposed in many nations, causing people to become
aware of the garment industry's negative effects. Some of the same firms
began to create clothes in a more sustainable manner, and there were groups
that propagated the concept of sustainable fashion all over the world.
Sustainability is described as development that meets current societal needs
without jeopardizing future generations' ability to meet their own. Eco-fashion,
also known as sustainable fashion, is fashion that has a lower environmental
impact throughout the entirety of the design, production, and consumption of
items. It entails prolonging the life of clothing, recycling, and reusing recycled
materials.
Ethical fashion is concerned with the environment, as well as the social impact
of the fashion industry. Ethical fashion is concerned with the use of child labor,
living wages, health and safety, working conditions, and the industry's use of
forced labor. It is also not only labor rules that are taken into account- ethical
fashion goes above and beyond to raise public awareness about the fair
treatment of employees, animals, and the other benefits of cruelty-free
fashion. Human lives and the environment are valued more than economic
profits in ethical designs, and organizations strive for dignified and honorable
working conditions.
On the other hand, fast fashion refers to clothing that is manufactured quickly
and cheaply to fit with the constantly changing trends. Fast fashion is
something we should avoid because it has been linked to massive amounts of
waste, highly polluted manufacturing processes, and awful working conditions.
Some of the worst offenders are H&M, TopShop, Zara, Zaful, Shein, Fashion
Nova, Missguided, and BooHoo. Due to demand from environmentally
conscious clients, firms such as H&M have become slightly more inclined to
ethical fashion and sustainability.
8. History of Eco-Fashion Continued
The precursor for all modern eco-fashion movements is the Pre-Raphaelite
movement. The Pre-Raphaelites foresaw the negative impact of new fashion
and the methods for making it that industrialization brought. These people had
a large impact on later fashion, as they rejected the restrictive corsets and
crinoline supports women of that time wore. They chose to dye their garments
with natural vegetable dyes instead of chemical dyes, even though the
chemicals created a brighter hue.
The 1960s saw young people revolting against the establishment through
their clothing, lifestyle, and music choices. These adolescent 'hippies' were
also anti-fashion. They welcomed natural materials and advocated for a return
to a simpler way of life, in contrast to the dominant highly consumerist society
of the day. They were the pioneers of environmentally friendly fashion. In the
late 1980s, there was a movement against fur, which marked the beginning of
the ethical fashion movement. This movement was extremely effective, since
it resulted in the abolition of actual fur from fashion.
However, the rise of offshore manufacturing and worldwide communication
saw the emergence of fast fashion- apparel that was inexpensive, instantly
accessible, and disposable. People stopped looking for quality and the
tendency of buying new garments every season took hold. Increased demand
resulted in increased output. During this period of fast fashion, the eco-fashion
movement began to seep into clothing. The Ecollection was launched by
Esprit, and Katharine Hamnett and Patagonia began to educate the public
about the horrible environmental impact of the fast fashion business. But,
tragically, the plight of this industry's workers, who live in the far east and work
day and night under appalling working conditions, was revealed only after
Bangladesh's Rana Plaza fell in 2013.
This was the most tragic catastrophe in fashion history, with over 1000 people
killed. The history of eco-fashion witnessed increasing attention as individuals
throughout the world realized how their decisions affected the lives of those
who made their items. Today, a rising number of people on the earth make
their clothing choices with ethical wear in mind, rather than simply buying
clothes. Every decision is significant and can make a difference!
9. Evolution of Sustainable Development
There has been agreement throughout the evolution of "sustainable development" that
it does not focus simply on environmental challenges. Economic development, social
development, and environmental protection are the three interrelated and mutually
reinforcing pillars. Indigenous peoples have maintained that cultural diversity is also a
fourth pillar of sustainable development. The concept of sustainability dates back to
the early twentieth century, during the industrial revolution, when two conflicting
factions within the environmental movement emerged: environmentalists and
preservationists. Conservationists were concerned with the right use of nature,
whereas preservationists were concerned with the protection of nature from use. To
put it another way, conservation tried to restrict human use, whereas preservation
sought to eradicate all human impact.
Several reactions occurred as the first signs of an environmental disaster emerged.
Following an international summit in Fontainebleau, France, the International Union for
Conservation of Nature (IUCN) was created in October 1948. Its proponents aimed to
ensure that any use of natural resources is equitable and environmentally sustainable.
The Club of Rome, a think tank comprised of a small international group of people
from academia, civil society, diplomacy, and industry, drew significant public attention
in 1972 with its report The Limits to Growth, which predicted that economic growth
could not be sustained indefinitely due to the limited availability of natural resources
(particularly oil).
The United Nations Conference on the Human Environment in Stockholm in 1972
made sustainable development a central focus. The term was coined to imply that
economic growth and industrialization could be achieved without causing
environmental damage. Throughout the following decades, mainstream sustainable
development thinking was gradually developed through the World Conservation
Strategy (1980), the Brundtland Report (1987), and the United Nations Conference on
Environment and Development in Rio (1992), as well as in national government
planning and wider engagement from business leaders and non-governmental
organizations of all kinds.
The definition of sustainable development has evolved over the decades. The
Brundtland Report defined sustainable as “development that satisfies the demands of
the present without compromising the ability of future generations to meet their own
needs.” This description was ambiguous, but it successfully addressed two essential
issues: the challenge of environmental deterioration that frequently accompanies
economic expansion, and the need for such progress to alleviate poverty.
10. Rise of the Eco-Friendly Consumer
In recent times, changes in climate have significantly impacted countries across
the globe. Customers and businesses alike are looking for ways to implement
and promote sustainable business practices in response to the changing climate.
It is crucial to consider how to meet climate targets in a real and significant way
that is in line with customer requirements and beliefs.
Customers may have run out of toilet paper during the peak of the COVID-19
pandemic, or they may have unsuccessfully sought online for an inflatable
backyard pool. For those confined at home, however, there was one resource
that was never-ending: time. Given greater time to reflect on routine activities
and decisions, many people began paying attention to how their shopping
choices affected the environment. Consumers have started to place a higher
priority on sustainability before the pandemic. However, half of all worldwide
consumers surveyed in PwC's June 2021 Global Consumer Insights Pulse
Survey claim to have become even more environmentally conscious.
Only 35% of respondents to PwC’s 2019 Global Consumer Insights Survey said
they looked for ecologically friendly packaging, 37% said they looked for
sustainable items, and 41% said they avoided using plastic wherever possible.
According to PwC's survey findings, responses to questions with comparable
wording were ten to twenty points higher in percentage. A study conducted by
market research company YouGov and creative research platform Visual GPS
shows a change during the pandemic. The results of that survey show that 69%
of respondents claimed they were doing everything possible to limit their carbon
footprint (up from 63% just a year earlier), and 81% of those asked expected
businesses to be environmentally responsible in their advertising and marketing.
Millennials displayed the most shift in green consumerism. According to a PwC
survey of 58% of "core" millennials (those between the ages of 27 and 32), they
have become more environmentally conscious. The majority of core and "young"
millennials (those between the ages of 23 and 26) also concur that they
intentionally think about sustainability when they shop. Generation Z is less
committed to eco-consumerism than millennials, which may be related to the
idea that shopping sustainably is more expensive or challenging.
11. Evolution of Renewable Energy
Countries all over the world desired alternate power production
technologies to serve their rapidly expanding electrical sector because
fossil fuels like coal and gas are a restricted resource only found in a few
geographic locations. Over the past 20 years, the price of coal has
fluctuated wildly, from $50 to more than $130 USD per metric ton.
Countries had to diversify their energy generation mix by localizing
resources that were independent of any supply chain restrictions in order
to ensure a stable electrical sector, which is a basic gauge of growth.
Scientists from all over the world concur that human activity is currently
causing global warming, which must be reduced. People all throughout the
world looked up to their governments and sought effective climate change
answers. Governments from nearly 200 nations paid heed and reached an
agreement in the historic Paris Climate Agreement to reduce carbon
emissions in order to lessen the effects of global warming. The majority of
countries saw renewable energy sources as the best way to combat
climate change. Germany came up with a bold plan to generate 50% of its
electricity from renewable sources by 2030. The National Solar Mission
was established by India with the objective of deploying 100 Gigawatts of
solar energy by 2022.
Globally, similar objectives have been set, and various government
subsidies as well as feed-in tariffs and renewable portfolio standards have
been used to encourage the use of renewable energy for power
generation. Today, for at least two-thirds of the world's population, onshore
wind and solar power are the most affordable sources of electricity. By
2030, it will be less expensive to construct renewable energy power plants
than to operate coal power plants all over the world. Over 26% of the
world's electricity generation as of the end of 2018 came from renewable
energy sources like solar, wind, and hydropower.
12. The Benefits of Recycling
Did you know that recycling helps reduce emissions of greenhouse gasses
like carbon dioxide and others that cause climate change? The 20 million
tons of home recyclables that are currently tossed in the trash could be
totally recycled, which would result in a 96 million metric ton reduction in the
nation's greenhouse gas emissions. With just recycling, we could accomplish
the same result as removing more than 20 million cars from American
highways! To take it a step further, we can and should recycle our junk cars,
as it conserves natural resources, reduces pollution, avoids excessive use of
energy, and much more.
Recycling is good for the economy as well as the environment. If all of the
37.4 million tons of recyclables produced by American households were
collected curbside and returned to productive use, 370,000 additional full-
time equivalent employment would be created. These "green occupations"
may involve curbside recycling collection, processing of recycled materials,
delivery of goods to businesses, transportation of materials, equipment
maintenance, and other tasks. When you recycle junk cars, you are helping
to create jobs at salvaging companies, which it turns helps to stimulate the
economy.
Recycling helps us to reuse our waste materials in new goods, promoting a
"circular economy" that reduces waste and permits ongoing resource
utilization. Why is that crucial? Because there are only a finite number of
natural resources on the planet. Without recycling, we are forced to rely on
obtaining raw materials through extraction and logging to meet our
manufacturing demands. This may lead to the destruction of habitats for
wildlife, costly and dangerous mining operations to collect metal ores, and
the depletion of minerals that cannot be replenished. However, recycling
allows us to more effectively protect and prolong these natural resources.
13. Evolution of Eco-Friendly Transportation
With transportation accounting for nearly 64% of worldwide oil consumption,
27% of total energy use, and 23% of global carbon dioxide emissions, it is
clear that transportation is at the heart of many economic and social
development concerns. Rethinking and redesigning transit in the post-COVID
age by enacting structural changes would significantly reinforce some of the
favorable effects achieved by pandemic-control measures on emission levels
and air quality.
Systems of transportation that are environmentally, socially, and economically
sustainable benefit the communities they serve. People readily take
advantage of the opportunities presented by greater mobility, with low-income
households benefiting considerably from low-carbon transportation options.
Transport infrastructures exist to facilitate social and economic linkages. The
benefits of greater mobility must be evaluated against the costs that
transportation systems place on the environment, society, and the economy.
Long-term objectives include moving transportation away from fossil fuel-
based energy and toward other options including the use of renewable energy
and other renewable resources. Short-term action frequently supports
incremental progress in fuel efficiency and vehicle emissions controls.
Measurement and optimization of sustainability are applied across the whole
life cycle of transportation systems.
According to the United Nations Environment Programme (UNEP), it would be
possible to save 2.4 million premature deaths per year due to outdoor air
pollution. Black carbon emissions, a part of particulate matter that is known to
induce respiratory and cancerous diseases and to significantly contribute to
global climate change, are particularly harmful to human health. Low-carbon,
eco-friendly transportation is becoming an increasingly sustainable
investment at the local level due to the connections between greenhouse gas
emissions and particulate matter. This is true both in terms of reducing
emissions and thereby preventing climate change, as well as enhancing
public health through improved air quality.
14. How Humans Impact the Environment
Numerous human activities such as overpopulation, pollution, the burning of
fossil fuels, and deforestation have an adverse effect on the physical
environment. Climate change, soil erosion, poor air quality, and undrinkable
water have all been brought on by changes like these. These unfavorable
effects may influence human behavior and lead to large-scale migrations or
conflicts over access to clean water.
There is no denying that human activity has a negative impact on the
environment. Earth is impacted by how we live our lives, what we produce and
consume, and how we move around. The effects of people on our environment
are extensive, affecting both terrestrial and aquatic ecosystems, and range from
ozone depletion to acid rain, human-induced soil degradation through
deforestation, pollution, and loss of species. We must be conscious of these
effects and seek to minimize them if we want to save the earth. Even if it's not
always simple, doing so is essential if we want to preserve the planet for future
generations.
15. Overpopulation
More than 7.8 billion people currently live on Earth. According to the UN,
population is projected to reach 10.8 billion by 2100, assuming stable fertility
reductions across many nations. Fascinatingly, 7.3 billion people could live
on the planet in 2100 if additional advancements in women's reproductive
autonomy and fertility decline more than the UN estimates is likely. Currently,
the world's population is still growing by a significant amount each year
(about 80 million people), and we are running out of essential nonrenewable
resources. These unsustainable trends are a result of a variety of reasons,
such as declining death rates, underuse of contraception, and a lack of
education for girls.
Population growth will unavoidably put strain on the environment, causing
more deforestation, less biodiversity, and increases in pollution and
emissions, all of which will worsen climate change. In the end, many experts
think that the added stress on the planet will cause ecological disruption and
collapse that is so severe it threatens the viability of life on Earth as we know
it if we don't take action to help minimize further population growth going into
the rest of this century. The health of the world is significantly impacted by
every increase in global population. According to estimates from a study by
Wynes and Nicholas (2017), in industrialized countries, a family with one
fewer child might reduce emissions by 58.6 tonnes CO2-equivalent year.
16. Pollution
When dangerous gasses and particulates are present in our air, this is referred
to as air pollution. Nine out of ten people worldwide breathe dirty air, but many
people are not aware of the possible negative effects of poor air quality on
their health and the environment. When dangerous gasses and chemicals are
discharged into the atmosphere, air pollution results. These pollutants include
sulfur dioxide, nitrogen oxide, and particulate matter (extremely minute
particles that enter our respiratory system). The majority of these pollutants
are released by human activity, including burning fossil fuels, driving, and
emissions from industry and agriculture.
Our health is significantly impacted by air pollution, which also shortens lives
and lowers quality of life. In actuality, it poses the greatest single
environmental health concern in the globe. It makes breathing problems worse
and raises the possibility of asthma episodes, which results in more hospital
admissions. Serious medical disorders like cancer, heart attacks, and strokes
can be brought on by prolonged exposure.
In actuality, air pollution contributes to one in three global fatalities from heart
attacks, lung cancer, and chronic respiratory diseases. We are all impacted,
but those in our society who are most at danger—particularly children and the
elderly—are at greater risk. Children who are exposed to air pollution may
experience respiratory problems and lung development delays. A growing
corpus of studies has also revealed linkages between air pollution and other
diseases like diabetes, children's developmental issues, and dementia.
17. Global Warming
The total annual global temperature rise during the Industrial Revolution has
been little over 1 degree Celsius, or over 2 degrees Fahrenheit. It increased
on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10
years between 1880—the year that accurate recordkeeping started—and
1980. The rate of growth, however, has more than doubled since 1981: Over
the past 40 years, the yearly global temperature has increased by 0.18
degrees Celsius, or 0.32 degrees Fahrenheit, every decade.
The outcome? a world with unprecedented heat. Since 2005, nine of the ten
warmest years on record since 1880 have happened, and the last five
warmest years have all happened since 2015. Deniers of climate change
have claimed that the rate of increase in global temperatures has "paused"
or "slowed," however several studies, including a 2018 research published in
the journal Environmental Research Letters, have refuted this assertion.
People all across the world are already suffering from the effects of global
warming.
Now, climate scientists have concluded that if we want to prevent a future in
which daily life throughout the world is marked by its worst, most devastating
effects: the extreme droughts, wildfires, floods, tropical storms, and other
disasters that we refer to collectively as climate change, we must limit global
warming to 1.5 degrees Celsius by 2040. All people experience these
consequences in one way or another, but the poor, the economically
disadvantaged, and people of color experience them the most keenly
because these groups are frequently those most affected by poverty,
eviction, hunger, and social unrest.
18. Climate Change
Long-term changes in temperature and weather patterns are referred to as
climate change. These changes could be caused by natural processes, such
oscillations in the solar cycle. But since the 1800s, human activities—
primarily the combustion of fossil fuels like coal, oil, and gas—have been the
primary cause of climate change. Fossil fuel combustion produces
greenhouse gas emissions that serve as a blanket around the planet,
trapping heat from the sun and increasing temperatures.
Carbon dioxide and methane are two examples of greenhouse gas
emissions that are contributing to climate change. These are produced, for
instance, while burning coal or gasoline to heat a building. Carbon dioxide
can also be released during forest and land clearing. Methane emissions are
primarily produced by waste landfills. Among the major emitters are energy,
industry, transportation, buildings, agriculture, and land use.
Unfortunately, emissions levels continue to rise. The finding is that the Earth
has warmed by around 1.1°C since the late 1800s. The most recent ten
years (2011–2020) were the warmest ever. Many believe that rising
temperatures are the main effect of climate change. But the story doesn't
start with the temperature increase. Changes in one place might have an
impact on changes in all other areas since the Earth is a system in which
everything is interconnected. Intense droughts, water scarcity, destructive
fires, rising sea levels, flooding, melting polar ice, catastrophic storms, and a
decline in biodiversity are currently some of the effects of climate change.
19. Genetic Modification
Fewer carbon dioxide emissions. Better soil. Increased food production
with reduced acreage. minimal food waste All of this can be achieved
without compromising the nutritional quality, the health and safety of
people, or the environment—in some cases, it can even be improved.
GMOs are the topic at hand, yes.
Do you picture enormous strawberries or seedless watermelons when
you consider the advantages of GMOs? In general, yes. The surprising
thing is that neither of those things has anything to do with GMOs. Each
GMO crop exists to answer various concerns farmers have in feeding and
supplying an expanding world with fuel, including addressing
environmental issues. Environmental sustainability is vital to all kinds of
agricultural production, whether traditional, organic, or genetically
modified. GMO crops and the features they express have had an
exceptional positive impact on the environment during the past 25+
years.
GMO seeds are one of the tools farmers use to grow crops that will feed
the world while leaving enough land for people to live on. Farmers can
achieve better harvests while using less land because GMO crops
directly combat critical challenges such as pests, weather, disease, and
food waste. Growing the same amount of crops without the use of GM
seeds would have required 23.4 million more hectares/57.8 million more
acres of land in 2020 alone. That is larger than the entire state of Idaho!
GMO crops have helped to reduce pesticides' overall environmental
impact by 17.3%. Herbicide-tolerant (HT) crops enable farmers to lessen
the number of treatments and treat fields with pesticides, frequently
glyphosate, rather than tilling. Glyphosate is a preferred pesticide among
farmers since it is safe for the environment and effectively eliminates a
variety of weed species. This means that rather than using several
herbicides repeatedly throughout the season, farmers can use a smaller
number of herbicides less frequently, similar to using one broad-spectrum
sunscreen rather than UVA and UVB protection.
20. Ocean Acidification
Climate change isn't the only effect of carbon pollution caused by fossil fuels.
As if driving global temperature rise wasn't bad enough, increased carbon in
our atmosphere is also to blame for the rapid acidification of our planet's
oceans. Our oceans are an incredible carbon sink, absorbing approximately
25% of the carbon dioxide produced by humans each year. However, this is
drastically altering sea surface chemistry: when carbon dioxide is absorbed by
the ocean, it dissolves to form carbonic acid. As a result, the ocean becomes
more acidic, upsetting the delicate pH balance on which millions upon millions
of organisms rely.
Our seas have become about 30% more acidic since the Industrial Revolution,
a rate not seen in 300 million years. This has far-reaching implications for
marine ecosystems as well as the billions of people who rely on the ocean for
food and survival. It's no coincidence that the oceans became more acidic
after the Industrial Revolution. As humans continue to burn more fossil fuels,
the concentration of carbon dioxide in our atmosphere rises, driving climate
change and raising both air and sea temperatures.
But climate change isn't the only effect of carbon pollution; ocean acidification
is as well. As the amount of carbon dioxide in the atmosphere increases,
oceans absorb more and more of it, becoming - you guessed it - more acidic.
This is happening at an unprecedented rate, and it will continue indefinitely
unless we stop using dirty fossil fuels. Ocean acidification endangers more
than just marine ecosystems. It also puts strain on human food systems and
has an impact on the livelihoods of people who rely on the ocean for a living in
a variety of ways, from fishing to tourism.
21. Water Pollution
Water pollution occurs when harmful substances, most often chemicals or
microorganisms, contaminate a stream, river, lake, ocean, aquifer, or other
body of water, lowering water quality and making it toxic to humans or the
environment. Water is particularly susceptible to pollution. Water, also known
as a "universal solvent," can dissolve more substances than any other liquid
on the planet. It's what gives us Kool-Aid and brilliant blue waterfalls. It is also
the reason why water is so easily polluted. Toxic substances from farms,
towns, and factories easily dissolve and mix with it, polluting the water.
Simply put, water pollution kills. According to a study published in The Lancet,
it was responsible for 1.8 million deaths in 2015. Water contamination can also
make you sick. Every year, approximately 1 billion people become ill as a
result of contaminated water. In addition, low-income communities are
disproportionately vulnerable because their homes are frequently located
closest to the most polluting industries.
Waterborne pathogens, such as disease-causing bacteria and viruses derived
from human and animal waste, are a major cause of illness caused by
contaminated drinking water. Cholera, giardia, and typhoid are among the
diseases spread by contaminated water. Even in wealthy countries, accidental
or illegal sewage treatment facility releases, as well as farm and urban runoff,
contribute harmful pathogens to waterways. Every year, Legionnaires' disease
(a severe form of pneumonia contracted from water sources such as cooling
towers and piped water) sickens thousands of people across the United
States, with cases ranging from California's Disneyland to Manhattan's Upper
East Side.
22. Overfishing
Overfishing occurs when too many fish are caught at once, causing the
breeding population to become too depleted to recover. Overfishing is
frequently associated with wasteful commercial fishing methods that bring in
massive amounts of unwanted fish or other animals, which are then
discarded. As a result of widespread and prolonged overfishing, nearly one-
third of the world's assessed fisheries are now in serious trouble — and that
figure is likely to be underestimated because many fisheries remain
unstudied. Overfishing threatens ocean ecosystems and the billions of
people who rely on seafood for protein. Without sustainable management,
our fisheries will collapse, resulting in a food crisis.
As fishermen caught fewer and fewer fish over time, mankind began to
realize that the seas, formerly thought to be infinitely large and bountiful, are
in reality extremely susceptible. A analysis of catch statistics published in the
journal Science in 2006 tragically predicted that if such unsustainable fishing
rates continue, all of the world's fisheries will be depleted by 2048. Many
scientists believe that with vigorous fisheries management and stronger
enforcement of catch rules, such as the implementation of catch limits, most
fish stocks may be restored. Increased usage of aquaculture, or fish farming,
would also be beneficial. And there is reason to be optimistic in many areas.
The United Nations Food and Agriculture Organization (FAO), which
establishes international standards for fisheries management, noted in its
2020 report that there has been a slight increase in the percentage of stocks
that are producing the most food possible in the most sustainable way
possible, which is the goal of fisheries management.
23. Deforestation
Deforestation is the planned, natural, or accidental clearing, destruction, or
removal of trees. It can exist in any region highly inhabited by trees and other
plant life, although it is most common in the Amazon jungle right now.
Climate change, desertification, soil erosion, less crops, flooding, higher
greenhouse gases in the environment, and a slew of other issues for
Indigenous people can all result from the loss of trees and other plants.
Deforestation happens for a variety of reasons. Agriculture is the most
common cause of deforestation, accounting for 80% of all deforestation,
along with logging for materials and development. It has been going on for
thousands of years, maybe since people began transitioning from hunter-
gatherer to agrarian societies, which required larger, unobstructed tracts of
land to support cattle, crops, and dwellings. However, it became an epidemic
following the advent of the modern age.
One of the most severe and disturbing consequences of deforestation is the
extinction of animal and plant species as a result of habitat loss. Forests are
home to 70% of all land animals and plant species. Deforestation endangers
not only known species, but also unknown ones. In in addition to diminishing
habitat, a lack of trees permits more greenhouse gases to be emitted into the
atmosphere. Healthy forests collect CO2 from the atmosphere and serve as
excellent carbon sinks. Deforested areas lose this ability, causing more
carbon to be released.
24. Acid Rain
Acid rain is characterized as precipitation that is excessively acidic due to the
presence of dissolved contaminants, making it capable of causing significant
environmental impact. Acid rain has a pH of around 4.0 due to the presence
of dissolved sulfur dioxide or nitrogen oxides, both of which are acidic
pollutants, whereas typical rain has a pH of around 5.5.
In general, the environment can adapt to a certain quantity of acid rain. Soil is
frequently slightly basic (due to naturally occurring limestone, which has a pH
of greater than 7). Because bases neutralize acids, these soils tend to offset
part of the acidity of acid rain. However, acid rain can impact the ecology in
locations where limestone does not naturally reside in the soil, such as the
Rocky Mountains and sections of the northwest and southeastern United
States.
Frogs, for example, have a difficult difficulty adapting to and reproducing in an
acidic environment. Acid rain and acid fog harm many plants, including
evergreen trees. I've witnessed some of the acid rain damage to evergreen
trees in Germany's Black Forest. Because so many of the green pine needles
had been killed, leaving just the black trunks and branches, most of the Black
Forest was indeed black! You may also note how acid rain has eroded the
stone in some city buildings and stone artwork.
Acid rain and the pollutant particles of sulfur dioxide and nitrogen oxide from
which it is created have been related to asthma, heart illness, and eye
irritation. Nitrogen oxides are also known to be involved in a mechanism that
produces tropospheric ozone, which is known to cause respiratory difficulties
in people.
25. Ozone Depletion
Human activities have significantly reduced the ozone layer's size during the
last few decades. This issue has been greatly exacerbated by the manufacture
of chemicals like halons, hydrochlorofluorocarbons, and chlorofluorocarbons
(CFCs). These substances, which are used in spray cans, air conditioners,
refrigerators, and many other devices, destroy ozone molecules when they are
released into the atmosphere. To safeguard the ozone layer, the Montréal
Protocol, an international agreement agreed in 1987, aims to gradually phase
down the production of CFCs, HCFCs, and halons. There has been some
progress, and the extent of the ozone hole is gradually starting to stabilize.
This global loss in stratospheric ozone is closely tied to increased levels of
chlorine and bromine in the stratosphere caused by the production and release
of CFCs and other halocarbons. Industry produces halocarbons for a number of
applications, including refrigerants (in refrigerators, air conditioners, and big
chillers), aerosol propellants, blowing agents for producing plastic foams,
firefighting agents, and solvents for dry cleaning and degreasing. Theoretical
studies have been well verified by atmospheric observations, which
demonstrate that chlorine and bromine emitted from halocarbons in the
stratosphere react with and destroy ozone.
Because ozone is a greenhouse gas, the ozone layer's breakdown and
predicted regeneration has an impact on the Earth's temperature. Scientific
analyses demonstrate that the drop in stratospheric ozone observed since the
1970s has generated a cooling effect—or, more precisely, that it has offset a
tiny portion of the warming caused by growing carbon dioxide and other
greenhouse gas concentrations during this time period. This cooling effect is
likely to fade as the ozone layer steadily recovers over the next few decades.
26. The Future of the Environment
The latest UN study on the state of the climate warns that humanity's future
may be plagued with horrific natural calamities. However, that future is not
fixed in stone. The world by the end of the twenty-first century could look very
different depending on global economic trends, technological advances,
geopolitical developments, and, most importantly, how aggressively we work to
reduce carbon emissions. Or not.
The estimates of the Intergovernmental Panel on Climate Change's (IPCC)
Sixth Assessment Report, whose first chapter on the physical science of
climate change was issued last week, are based on a spectrum of possible
futures. The new research includes five climate narratives that differ in terms of
expected warming and society's ability to adapt to future changes. Each tale
marries a distinct socioeconomic development scenario with a different carbon
emissions trajectory, resulting in a range of endings to the story of 21st-century
climate change in the style of a Choose Your Own Adventure game.
In some of those endings, mankind rises to the climatic problem while also
working to decrease poverty and improve the quality of life for everybody. The
world is hotter and the weather is more dangerous, yet the worst effects of
climate change have been avoided, and cultures are adapting. In others,
nationalism, rising poverty, skyrocketing emissions, and unimaginably hot
weather are fracturing global collaboration.
The differing emission levels of the various scenarios cause different levels of
warming in climate models, resulting in a spectrum of physical repercussions
on the globe, according to the IPCC report issued last week. The implications
of the various socioeconomic storylines will be more prominent in the second
and third chapters of the new IPCC report, which will be released in 2022,
because these chapters will focus on climate adaptation and mitigation,
according to Jessica Tierney, a climate scientist at the University of Arizona
and an IPCC co-author.
