It defines ecosystems as dynamic interactions between organisms and their environment. Biodiversity is declining due to threats like habitat loss, pollution, and climate change. The document advocates for sustainable development, conservation of biodiversity hotspots, and restoration ecology to protect the environment for future generations.
Climate change is defined as long-term shifts in weather patterns over decades or longer. It is caused by both natural factors like ocean currents and human factors like burning fossil fuels. Effects of climate change include rising sea levels as glaciers and ice caps melt, more severe weather events, and harm to ecosystems. Global warming is a specific result of climate change where the average temperature of the Earth's atmosphere and oceans increase due to greenhouse gas emissions. Deforestation exacerbates global warming by reducing carbon absorption and increasing greenhouse gases in the atmosphere. Continued climate change will have widespread environmental, social, and economic impacts.
Climate change is caused by both natural factors and human activities like burning fossil fuels. Scientists use observations and models to understand past and predict future climate change. Climate change is already affecting different regions in the form of extreme weather, rising sea levels, and threats to animals and humans. Addressing climate change requires global cooperation to reduce greenhouse gas emissions through initiatives like adopting renewable energy and setting emissions standards. The UN works to facilitate international agreements like the Paris Agreement to coordinate a global response to this urgent issue.
This module explains the impacts of climate change on water resources and disasters. It covers climate variability, climate change, and the effects on sectors like agriculture, energy, transport, health and water resources. Adaptation is needed to build community resilience against hydro-climatic disasters through understanding impacts and applying knowledge from the module.
Reforestation involves replanting trees in forests that have been cut down or damaged. It helps reduce pollution by absorbing carbon dioxide, rebuild habitats, and mitigate global warming by storing carbon. Countries and organizations provide incentives for reforestation by financially compensating reductions in deforestation or requiring tree seedlings from weddings or divorces. Examples of reforestation efforts include programs in Indonesia, Malaysia, and other parts of the world.
Climate change can be assessed over short, medium, and long timescales. Short-term climate change like global warming occurs over decades, while medium-term changes happened over thousands of years in the past. Long-term climate change takes place over hundreds of thousands to millions of years. Human activities that release greenhouse gases like burning fossil fuels and deforestation are contributing to increased CO2 levels and global warming, but natural factors like variations in the Earth's orbit and volcanic eruptions have also caused climate changes in the past. The document discusses both human and natural causes and impacts of climate change.

This document discusses deforestation, its causes, and its consequences. It notes that deforestation occurs when forests are cleared for activities like agriculture, housing, and fuel. This removal of trees leads to issues like soil erosion, disruption of the water cycle, loss of biodiversity, and increased carbon dioxide in the atmosphere. To help address these problems, the document explains that protected areas like wildlife sanctuaries, biosphere reserves, and national parks have been established to conserve forests and wildlife. Reforestation efforts are also important to replenish harvested woodlands.
This document defines key terms related to environmental pollution. It defines environment as including water, air, land, and the interrelationships between these components and living organisms. Environmental pollution is defined as the presence of environmental pollutants, or substances that are or could be harmful, in the environment. The document also discusses various natural and artificial causes of environmental pollution, including population growth, industrialization, urbanization, and deforestation.
Natural resources are valuable substances that exist naturally and include necessities for human life like food. Overexploitation of natural resources in an unsustainable way can cause issues as estimates show some resources may run out soon if exploitation continues at current rates. Possible solutions include recycling, establishing new sustainable ways to use resources, promoting environmental values, and educating new generations on developing an environmental conscience.
About 11,000 years ago, before humans learned agriculture, forests covered much of the Earth's land. Today, after widespread deforestation, forests cover only about one-fifth of the planet's surface. Deforestation occurs for many reasons like using trees for fuel, timber, or cleared land for livestock or agriculture. The large-scale removal of trees without replanting has damaged habitats and biodiversity while increasing carbon dioxide emissions and soil erosion. Currently 12 million hectares of forest are cleared annually.

Biodiversity refers to the variety of life on Earth, including genetic, species, and ecosystem diversity. Loss of biodiversity is occurring at an alarming rate, with up to 20,000 species estimated to go extinct each year. Habitat destruction and fragmentation due to human activities like agriculture, construction, and urbanization are major drivers of biodiversity loss. Other threats include overexploitation of species, introduction of exotic species, pollution, climate change, and poaching. Widespread biodiversity decline poses serious risks to ecosystem balance, food security, natural disaster mitigation, and could ultimately threaten human survival if left unaddressed. Conservation efforts are needed to protect the estimated 24% of mammals and 12% of birds currently considered globally

This presentation by Dr Harikumar, Scientist, CWRDM made at the Kerala Environment Congress, Trivandrum organised by the Centre for Enviroment and Development provides information about the pollutants in the environmental sectors produced as a consequence of agricultural activities
Environmental degradation is the deterioration of the environment caused by depletion of natural resources and destruction of ecosystems from factors like pollution, deforestation, overpopulation, intensive agriculture, and land disturbance which can negatively impact human health, biodiversity, the economy and tourism. Major causes include land damage, rapid population growth straining resources, ruinous agricultural practices, deforestation, and pollution from sources such as factories, vehicles, and landfills. Environmental degradation if not addressed can lead to issues like illness, loss of biodiversity and wildlife, ozone layer depletion, and negative economic impacts.
Environment management - exploitation & modification of natural resourcesAnish Gawande
Natural resources refer to all materials in nature that are required by humans for their well-beings. In other words, humans are totally dependent on natural resources for survival. For instance, they grow crops, catch fish, and rear livestock and poultry for food; they exploit fossil fuels for energy supply; they cut down timber, extract minerals, and collect water for various uses in industry, construction, and many aspects in daily life. Natural resources are customarily classified into renewable resources and non-renewable resources.
Renewable resources are resources that can be regenerated fairly rapidly through natural processes. Examples include oxygen, minerals in soil, wildlife, timber, fish, and fresh water. Theoretically, these resources are renewed naturally and are always available. However, if the rates of use exceed the rates of renewal, the resources will become depleted.
Soil pollution can be caused by various sources like agricultural pesticides, disposal of solid waste, mining, urbanization, and industrial activities. It leads to negative effects like reduced soil fertility, crop yields, and groundwater quality. It can also pose various health risks to humans. Some key ways to prevent soil pollution include adopting sustainable agricultural practices, better waste management, reducing the use of toxic chemicals, recycling waste materials, and ensuring pollutants are properly disposed of.
Soil pollution is defined as changes to the physical, chemical, and biological properties of soil caused by human activity. It is caused by excessive use of chemicals like pesticides and fertilizers, soil erosion, industrial and urban waste, radioactive waste, and acid rain. Effects include reduced soil fertility, loss of nutrients, and damage to microorganisms, plants, and human health. Prevention methods include reducing chemical use, proper waste disposal, recycling, afforestation, and enacting environmental laws. Individuals and industries must work together to control measures like using biodegradable waste and minimizing chemical usage to reduce soil pollution.
Unit 1 ch1 s1 understanding our environmentwja10255
This document provides an overview of environmental science, including how humans interact with and impact the environment. It discusses the fields of study related to the environment, how early humans hunted and gathered with minimal impact but how the agricultural and industrial revolutions led to overpopulation and issues like resource depletion, pollution, and loss of biodiversity that threaten the environment.
The document discusses how humans impact the environment and various environmental issues. It notes that as the human population has increased from 10 million to over 6 billion in 10,000 years, our impact on the environment has also increased. Some key environmental issues discussed include air and water pollution, global warming, soil damage, and ecosystem disruption which can harm biodiversity. Solutions mentioned are conservation efforts to protect habitats and restoration to repair damaged areas.
This document discusses several environmental problems including overpopulation, climate change, loss of biodiversity, and biological invasions. Overpopulation can transform landscapes, increase demand for resources, and cause pollution. Climate change is exacerbated by human activities that increase greenhouse gas emissions like burning fossil fuels. Loss of biodiversity is caused by factors such as exploitation, habitat loss, invasive species, and deforestation, which has reduced forests by 70% globally. Biological invasions are responsible for 40% of extinctions in Colombia and are the second leading cause of species extinction worldwide.
Humans have brought Earth close to a biotic crisis by damaging the environment through various issues at the global, national, and local levels. These environmental problems have socio-economic and cultural impacts. The key issues include global warming, ozone layer depletion, acid rain, deforestation, loss of biodiversity, pollution, desertification, and waste disposal. While some environmental changes occurred naturally in the past, humans now have the potential to disrupt the entire global ecosystem if environmental damage is not addressed.
Soil pollution is characterized by the presence of harmful synthetic compounds in soil that pose hazards to human and environmental health. Land pollution is the destruction and pollution of land through direct and indirect human activities like deforestation, agricultural chemicals, industrialization, mining, landfills and fuel spillages. Major sources of soil pollution include domestic and industrial wastes, e-waste, and nuclear waste. Soil pollutants include detergents, heavy metals, pesticides, organic dyes, and pathogenic microorganisms. Effects of soil pollution are soils unfit for agriculture, spread of diseases, bioaccumulation of toxins, eutrophication, and contamination of groundwater. Control and mitigation involves treating efflu

Soil pollution occurs when harmful substances are introduced into soil, adversely affecting plant growth and animal health. Common causes of soil pollution include industrial waste discharge, pesticide overuse, landfill seepage, and urban/agricultural runoff. Effects range from reduced soil fertility and crop yields to contamination of water sources and changes in local ecosystems. Solutions involve reducing chemical use, recycling waste, proper disposal methods, and phasing out the most toxic substances. Overall soil pollution poses serious risks to both the environment and human health if not properly addressed.
Biology project on Causes of loss of biodiversitynaren25106
The document is a project study on the causes of biodiversity loss. It discusses several key factors that contribute to loss of biodiversity, including pollution, habitat loss, hunting, overexploitation of species, climate change, invasive species, and natural disasters. Pollution such as air, water, soil, light, and noise pollution negatively impact ecosystems. Habitat loss from activities like deforestation, agriculture, and urbanization fragments and destroys natural habitats. Overhunting and overexploitation of plant and animal species can drive them to extinction. Climate change also threatens biodiversity by disrupting ecosystems. Invasive species introduced by human activities can outcompete native species. Finally, natural disasters such as floods, wildfires,
This document discusses human impact on biodiversity. It begins with defining biodiversity as the variety of life on Earth, including diversity within and between species and ecosystems. It then outlines threats to biodiversity from habitat loss, pollution, overexploitation, invasive species, and climate change. The document emphasizes that biodiversity provides many benefits to humans through resources like food and medicine, as well as ecological functions. However, biodiversity loss is now occurring rapidly due to human activities. Conservation efforts are needed to protect biodiversity through both on-site and off-site methods.
Deforestation refers to the clearing of forests to make land available for human use such as agriculture, housing, and industry. This leads to serious threats including increased soil erosion, more frequent floods and droughts, loss of plant and animal species, and a warmer climate in deforested areas. Deforestation is caused by factors like population growth, extraction of wood for fuel and construction, agricultural expansion, fires, pests, and dams. Reforestation programs in India aim to reduce pressure on forests by promoting social forestry, agroforestry, urban forestry, and protected forest reserves.

Major environmental problems discussed in the document include pollution, hazardous chemicals and wastes, land degradation, loss of biodiversity, ozone depletion, climate change, and loss of natural and cultural resources. The document outlines the causes and impacts of these problems, as well as responses at national and international levels. National courts and tribunals play a key role in applying environmental law to address issues caused by national activities that have impacts domestically and globally. International cooperation, legislation, and financing support national efforts toward remediation.
Human activities have significantly impacted the natural environment in many negative ways:
1) Pollution of land, water, and air from industry, transportation, agriculture, and other sources has degraded ecosystems and harmed wildlife.
2) Deforestation and habitat destruction have caused widespread biodiversity loss and endangered many species.
3) Resource extraction and use, such as mining, farming, and fossil fuel energy production, have depleted natural resources and contributed to problems like climate change if not properly regulated.
4) Waste generation and disposal pose risks to land, water, and air quality if not managed sustainably.

2. Introduction
IT IS A WELL-KNOWN FACT THAT HUMANS HAVE BEEN LIVING AND MODIFYING THE
EARTH SINCE THE BEGINNING OF TIME
WE CONSCIOUSLY AND SUBCONSCIOUSLY DESTROY OUR PRECIOUS ENVIRONMENT WITH
THE INTENT OF MAKING LIFE EASIER AND ALSO GENERATING ECONOMICAL BENEFITS.
THE FUTURE OF THE EARTH REMAIN UNCERTAIN DUE TO THE DAMAGING IMPACT THAT
ARISE FROM INDIVIDUALS QUEST FOR FULFILLMENT, ECONOMIC ADVANCEMENT AND A
LACK OF RESPECT FOR THE ENVIRONMENT.
YET TO ALL ALARMING SITUATIONS ,SUCH AS GLOBAL WARMING , UNTIMELY CHANGE OF
THE SEASON,OZONE DEPLEITON ,EXTICTION OF MANY SPECIES AND MANY MORE .WE
HUMAN’S STILL ENJOY OUR DOMINATION OVER THE PLANET AND EXPLOIT THINGS
ACCORDING TO OUR NEED
IF THIS CONTINUES ITS EXPECTED ,WE WILL BE PACKING UP WITH OUR NATURAL NON-
RENEWABLE SOURCES OF ENERGY ,NO SUFFICIENT LAND EVEN TO GENRATE RENEWABLE
ENERGIES ,TEMPRATURE OF THE EARTH WILL RISE TO 5 TO 8 DEGREES,ONLY THE SPECIES
LEFT WOULD BE INSECTS AND HUMANS ,GLACIERS WOULD MELT COVERING HALF THE
PRESENT LAND WITH WATER
3. Impact of human on environment with their respective
Era’s of Evolution .
Human evolution with time Change in human’s activity
with time
Humans were mostly hunter gatherers Hunting & food
gathering
Agriculture revolution Settlement and agriculture
development, domestication of animal,
habitat development
(urbanization)
Industrial revolution Development of industrial
process, mining and fossil fuel
production , increase the use of
pesticide and chemical fertilizer .
Scientific advancements & Globalization Rapid technology and information
development, globalization on many
aspects
4. Agriculture revolution
• SETTLED AGRICULTURE HAS INCREASED FOOD SUPPLY THAT LEAD TO
SUPPORT MORE PEOPLE, BUT DECREASE THE ENVIRONMENT QUALITY
• PEOPLES CUT DOWN VAST FOREST TO SUPPLY WOOD FOR FUEL AND
BUILDING MATERIAL THUS LEADING TO SOIL EROSION
• PLOWED UP LARGE EXPANSES OF GRASSLAND TO GROW CROP TURNING
FERTILE LAND TO DESERT
5. Effect of modern agriculture on the air, soil, water
& biodiversity resources
Water pollution SOIL Air pollution
Aquifer deplition Erosion Green house gas emission from
Increased runoff & flooding form Loss of fertility Fossil fuel use
land cleared to grow crops Stalinization Other air pollutants from fossil
Sediment pollution from erosion Lateralization fuel use
Fish kills from pesticide runoff Water logging Pollution from pesticide sprays
Desertification
Loss and degradation of habitat
from clearing grasslands & forests
Fish kills from pesticide runoff Human health
Killing of wild predators to protect
livestock Nitrates in drinking Water
Loss of genetic diversity from Pesticides residues in food, air
replacing thousands of wild crop & water
strains with a few monoculture Contamination through livestock
Biodiversity loss strains waste
Bacterial contamination of meat
6. Raising livestock to produce meat & animal products by
open grazing is destroying ecosystems LIGHTLY

DUST STORM IN DELHI SORRY NOTHING TO FEED
7. Industrial revolution
• SHIFT FROM RENEWABLE ENERGY SOURCES TO NON-RENEWABLE ENERGIES
( FOSSIL FUELS). PRODUCTION NOW TOTALLY DEPEND UPON AVAIBILITY OF
THESE ENERGY RESOURCES.
• TO MEET THE CHANGE MAN STARTED UPROOTING THESE RESOURCES
BACKWARDING SUSTAINIBILITY OF ENVIORMENT
• APETITE & GREED FOR THESE RESOURCES SUDDENLY INCREASED AS HUMAN
CIVILIZATION MARCHED TOWARDS URBANIZATION AND SO DO WE STARTED
TO EXPLOIT
• WITH USE OF THESE NATURAL ENERGY RESOURCES , WE ACHIVED MANY
ADVANCEMENTS WITH TECHNELOGIES BUT AGAIN SIDELINNING THE
BY-PRODUCT , “POLLUTION”

10. Consequences of excessive use of fossil fuels on environment &
the animals
Surface and subsurface mining cause
pollution and degradation of stream
and groundwater by runoff of acids
Burning fossil fuels produces billions
tones of CO2, one of greenhouse gases
that contribute global warming.
A large amount Liquid fossil fuels can
seeps into ocean
Waste oil dumped from activities on land
Thus this oil leakage into oceans causes a
sudden collapse in marine ecosystem
11. Activity
Today the depth in which we had intervene the
earth’s natural cycle ,is to a extent that most of
the activity carried by us causes direct or indirect
harm to the environment
Even just a construction of road could lead
in destruction & degradation of land & the
ecosystem
Use of pesticides for controlling pest population
Its not only disbalances the natural cycle of insect
& their predators but also leads to soil infertility.
Further these insecticide travel up in the food
chain
12. ACTIVITY
Irreversible damage is being caused to soil due to various human activities mainly due to
Agriculture and industrialization
Today , though we understand the effect of which we had exploited the earth , still we are
landing towards the more worst conditions .
Soil Degradation Areas of degraded soil of the world
13. Overloading of waste in water to causing water
degradation
Only a tiny amount of world’s abundant water is available as fresh water (2.6%)
Rate at which water is being used is much faster then at which its replenished itself.
14. Our future sustainability
CLIMATE CHANGE WILL HAVE A SIGNIFICANT IMPACT ON THE SUSTAINABILITY OF WATER
SUPPLIES IN THE COMING DECADES. A NEW ANALYSIS, PERFORMED BY CONSULTING
FIRM TETRA TECH FOR THE NATURAL RESOURCES DEFENSE COUNCIL (NRDC), EXAMINED
THE EFFECTS OF GLOBAL WARMING ON WATER SUPPLY AND DEMAND IN THE
CONTIGUOUS UNITED STATES. THE STUDY FOUND THAT MORE THAN 1,100 COUNTIES --
ONE-THIRD OF ALL COUNTIES IN THE LOWER 35 -- WILL FACE HIGHER RISKS OF WATER
SHORTAGES BY MID-CENTURY AS THE RESULT OF GLOBAL WARMING. MORE THAN 400
OF THESE COUNTIES WILL FACE EXTREMELY HIGH RISKS OF WATER SHORTAGES
15. Climatic change : Again due to human
activities
Today our planet is hotter to 2 degree Celsius as compared to what was in the start of
industrial revolution.
It doesn't sound like much, but relatively small fluctuations like that can have a
significant impact over a wide surface. A 5 degree to 8 degree rise in global temperature
in the next 50 years, expected by many scientists, could cause sea levels to rise half a
meter and put some island nations underwater
Tough a concrete jungle are providing a good habitat for human’s ,but it bifurcates the
Law of natural cycle .
16. Man –vs - Animals
HUMAN’S AGAIN DOMINATED THE EARTH WITH THEIR ABILITY AND SKILLS IN
MANIPULATING & MODIFYING THE EARTH’S NATURAL SYSTEM
HUMAN’S STARTED TO HUNT AND DOMESTICATE ANIMALS SO AS REQUIRED
ANIMALS DOMESTICATED ,NOW COULD NOT SURVIVE WITHOUT HUMAN INTERFEARENCE
DUE TO EXCESSIVE HUNTING MANY ANIMAL SPECIES HAD EXTINCT OR ON A VERGE OF
EXTINCTION
LIFE WITHOUT
HUMAN’S -
IMPOSSIBLE
17. SCIENTIFIC ADVANCEMENT’ S &
GLOBALISATION
CREATING AND INTRODUCING NEW TECHNOLOGIES MUCH FASTER THAN WE CAN
EVALUATE THEIR IMPACTS
PRESENT IT SECTOR DEVELOPMENT ARE CAUSING CONFUSION, DISTRACTION AND
SENSE OF HOPELESSNESS AS RAPIDLY GROWING ENVIRONMENTAL INFORMATION
INCREASE ENVIRONMENTAL DEGRADATION AND DECREASE CULTURAL DIVERSITY AS A
GLOBALIZED ECONOMY SPREADS OVER MOST OF THE EARTH
THOUGH RAPID DEVELOPMENT & URBANIZATION IS THE CAUSE OF ALL THE PRESENT
SCENARIO OF ENVIRONMENTAL UPSET, IT IS ONLY THE CAUSE THAT PEOPLE ARE
UNDERSTANDING AND EXCHANGING THEIR THAUGHTS FOR SAVING THE ENVIRONMENT
