natural resources- water, air , food , organic and inorganicNaveen Prabhu
This document discusses natural resources including renewable resources like soil, water and air and non-renewable resources like minerals and fossil fuels. It then focuses on forest resources, highlighting that forests cover about 1/3 of the world's land area and provide commercial and environmental benefits. The document also discusses overexploitation of forests through activities like shifting cultivation, fuel collection and infrastructure development. It notes the effects of deforestation and describes forest conservation methods.
The document defines key terms related to ecosystems: a population is one species living in an area, a community is made up of multiple populations in an area, and an ecosystem includes all living and non-living interactions. An ecosystem has biotic components like plants and animals, and abiotic components like water, air, and soil. Organisms are organized into trophic levels based on their position in a food chain, with producers at the base and tertiary consumers at the top. Food chains show energy transfer between organisms, and food webs combine all the food chains in an ecosystem. The document also discusses how human activities like pollution and construction can impact ecosystems, and how humans can help prevent changes through conservation efforts.
This document discusses the structure and function of ecosystems. It defines an ecosystem as a community of living organisms interacting with each other and their non-living environment. An ecosystem includes biotic components like producers, consumers, and decomposers, as well as abiotic components from the lithosphere like soil, water, and weather. It then explains key ecosystem functions - productivity refers to the rate of biomass production, decomposition recycles organic matter into nutrients, energy flows through the ecosystem from producers to consumers, and nutrients cycle through the living and nonliving components of the ecosystem.
1. The document outlines topics to be covered in an applied chemistry class including control of air, water, and soil pollution, environmental legislation, case studies, and hazards in various industries.
2. It then discusses the relationship between human and environmental systems, describing them as complex and adaptive. It explains how human activities impact the environment and vice versa.
3. Key ways people interact with the environment include using natural resources, deforestation, energy use, oil and gas extraction, water use, and littering. However, humans can also protect the environment through conservation efforts and sustainability.
The document defines several types of environmental issues: pollution as harmful substances in the environment, renewable resources that can be reused versus nonrenewable resources that cannot, alien species that establish themselves in new environments, overpopulation exceeding available resources, biodiversity as biological variety, and deforestation as forest clearing. It also describes wetlands for controlling floods and filtering water while providing animal habitats. It prompts calculating one's ecological footprint to understand resource use and ways to reduce environmental impact.
Ecology - Foundation Course Semester 2- Prof. Karishma Shetty KarishmaShetty16
This document discusses the importance of environmental studies. It notes that environmental studies will help develop sustainably without destroying the environment, educate people on efficiently using resources, and highlight environmental issues to work on resolving. It also discusses key concepts related to environment and ecology, including defining ecology as the study of organism interactions and their environment. Components of the environment and types of ecosystems are also outlined.
Individuals can positively or negatively impact natural resources like forests and fossil fuels. Forests provide important functions like producing oxygen and housing wildlife, but are threatened if cutting exceeds regrowth. Fossil fuels take millions of years to form but are being consumed faster than replaced, and their combustion pollutes the air. Alternative resources like solar and wind energy do not pollute or deplete over time if harnessed sustainably. Overall resource preservation requires consideration of both environmental and human needs.
Green plants use energy from the sun to transform water, carbon dioxide, and minerals into oxygen and organic compounds through the process of photosynthesis. Photosynthesis is an example of how people and plants are dependent on each other to sustain life. The document provides an excerpt about photosynthesis from a website.

An ecosystem is defined as a unit consisting of living and non-living components that interact in a defined area. It includes biotic components like producers, consumers, and decomposers, as well as abiotic factors like climate and soil. Producers like plants harness energy from the sun through photosynthesis. Consumers feed on producers or other consumers, and decomposers break down dead organic matter. Ecosystems provide functions like nutrient cycling, food production, and evolution, and services such as food, fuel, soil formation, and pollution control. Ecosystems are classified as terrestrial or aquatic and come in different types depending on location and components.
Ecology is the study of the interrelationships between living organisms and their environment. It examines how organisms interact with each other and with abiotic factors in their environment. The document discusses key topics in ecology including ecosystems, energy flow, and ecological pyramids. An ecosystem is defined as a community of organisms interacting with each other and their non-living environment. Energy from the sun enters ecosystems and flows through trophic levels from producers to consumers to decomposers. Ecological pyramids graphically represent trophic structures and can track numbers, biomass, or energy at each level.
Water is essential for life on Earth and plays many vital roles in the human body such as regulating temperature, transporting oxygen, and removing waste. However, water pollution occurs when substances are introduced into water that make it harmful for human use. Pollution can originate from industrial, agricultural, residential or natural sources and contaminate surface water, groundwater, and atmospheric water. The causes of water pollution include wastewater, solid waste, eutrophication, and toxic inorganic and organic chemicals from human activities. To address water pollution, methods must simultaneously preserve aquatic ecosystems, protect public health, and develop human resources.
The document discusses various sources and types of water pollution. It outlines point sources which directly emit pollutants into water and non-point sources which load pollutants over large areas. Specific pollutants mentioned include pathogens, toxic chemicals, excess nutrients, sediments, thermal pollution, and petroleum. Solutions proposed to address water pollution involve reducing pollutants at their sources and improving wastewater treatment before discharge.
The document provides information on different types of wastes, ecosystems, and environmental issues. It discusses:
1) Biodegradable wastes such as food and paper break down naturally, while non-biodegradable wastes like plastics persist and can pollute the environment.
2) An ecosystem includes both biotic (living) and abiotic (non-living) components that interact, along with food chains connecting producers, consumers, and decomposers.
3) Environmental problems arise from pollution and depletion of resources. The thinning ozone layer allows more UV radiation to reach the Earth's surface, increasing health risks, while waste disposal methods must account for different waste types.

Kinga Krauze: Securing Wellbeing: Nature Based Solutions in Urban Water Manag...THL
The document discusses nature-based solutions for urban water management. It proposes using ecosystem properties and green infrastructure to regulate hydrology and biota through dual regulation. This involves harmonizing ecohydrological measures with necessary infrastructure and integrating various regulations to stabilize and improve water quality. Nature-based solutions could help with urban regeneration, coastal resilience, and more sustainable resource use while enhancing ecosystem services. However, their actual benefits depend on proper planning and management across spatial scales from cities to suburban areas. Societal choices also influence the adoption of such solutions.
The document discusses various natural disasters that have occurred over the past century including earthquakes, tsunamis, hurricanes, and pandemics. It provides details on specific devastating natural disasters like the 2008 Sichuan earthquake in China that killed nearly 10,000 people, and the 2011 Tohoku earthquake and tsunami in Japan that caused over 350 deaths. The document also suggests various ways to help protect the environment such as planting trees, conserving water and energy, reducing waste, and using renewable resources and public transportation.
An ecosystem includes all living and non-living things in a defined area that interact with each other. It describes the complex web of interactions between organisms and their environment. Each organism has a role, and the ecosystem as a whole determines the health of the biosphere. When a new organism or factor is introduced, it can disrupt this natural balance and potentially harm the ecosystem. Ecosystems face many threats including habitat destruction from human activities, pollution, overharvesting of resources, and increased UV radiation from ozone depletion. These threats can destroy ecosystems by altering the delicate balance of interactions.
Natural resources are living things from the Earth that living things need. Trees are an example of a natural resource that is renewable, meaning it can be replaced in a fairly short time. A nonrenewable resource is one that cannot be replaced once it is used up, such as coal, which forms from ancient plants. Conservation involves the wise use of natural resources so that they are not wasted or used up.
This chapter discusses ethics and the environment. It explains different types of pollution like air, water, noise, and toxic substances pollution as well as resource depletion issues.

It concludes by discussing pollution control and conservation efforts to ensure resources are available for future generations.
This document discusses environmental problems, their causes, and sustainability. It explains that human activities can degrade natural capital by overusing renewable resources. Environmentally sustainable societies must protect natural capital and live within its limits to ensure resources are available for future generations. The main causes of environmental degradation are population growth, unsustainable resource use, poverty, and the exclusion of environmental costs from market prices.
The document discusses human waste and its impacts on the environment. It describes two main types of waste - biodegradable waste that can be decomposed, like food scraps, and non-biodegradable waste, like plastics, that persist in the environment and cause pollution. The document then provides several methods for proper waste disposal, including landfills, recycling, composting, and incineration, to reduce pollution impacts.
The document summarizes the study of natural resources in Ahirori Block, Hardoi, Uttar Pradesh. It finds that the area has productive soil suited for agriculture, especially pulses. It also has abundant water resources like wells, canals, ponds, lakes and rivers. However, soil and water resources are under threat from excessive use of fertilizers and pesticides. The area lacks forests but some villagers have planted trees. Solar energy is being utilized through street lights installed under a government program. Animals are an important livelihood resource but are negatively impacted by wild animals and degraded fodder.
Natural resources are materials and components found within the environment that can be used by humans. They include inexhaustible resources like solar radiation, air, and water that exist in unlimited quantities, as well as exhaustible resources like soil, forests, wildlife, and minerals that have limited supplies. The document discusses several key natural resources in more detail, including their importance and various human uses. It also notes that depletion of resources and competition over exports has led to global debates over natural resource allocations.
This document discusses how people use natural resources like water. It provides information on the major ways water resources are used: agriculture, industry, households, recreation, and environmental activities. For agriculture, it notes that 69% of water worldwide is used for irrigation. For industry, it estimates that 15% of water use is industrial, in areas like power plants. It also provides proposals for conserving water resources like educating people to close taps when not in use and preventing water pollution from trash and fertilizers. The document discusses some issues with water resources like climate change impacts, business expansion pressures, and recent news about water privatization efforts in Colombia.

The document discusses the hydrological cycle and hydrosphere. It provides details on the various components of Earth's hydrosphere, including oceans, ice sheets, groundwater, lakes and rivers, atmospheric moisture, and biological water. It explains that the hydrological cycle involves evaporation and transpiration of water from surfaces into the atmosphere, condensation to form precipitation, and precipitation returning water to Earth's surface. Adding water to the system through aquifer drawdown and pumping fossil water increases evaporation and cloud cover, absorbing infrared radiation and impacting the climate system.
The document discusses the global water shortage problem. It notes that while water covers 70% of the Earth's surface, only 3% is freshwater and 1% is accessible for human use. The shortage is exacerbated by population growth and climate change. Improper water management practices like pollution and overuse in agriculture are also contributing factors. Potential solutions proposed in the document include increasing water recycling and conservation efforts, as well as implementing more sustainable agricultural practices.
This document discusses various aspects of water resources including:
1) Water is found in three main forms - saltwater in oceans, freshwater in lakes/rivers/groundwater, and frozen water.
2) The water cycle describes the continuous movement of water between these forms through evaporation, condensation, precipitation and other processes.
3) Water resources are essential for agriculture, industry, and human/environmental needs but are increasingly threatened by pollution, overuse, and climate change. Integrated management plans are needed to ensure sustainable access.

It describes how precipitation forms, the hydrological cycle of water moving through the atmosphere and environment, and infiltration and runoff processes. It aims to explain these environmental processes and the human impacts on water, land, air, energy resources, and fisheries.
Water pollution is a serious issue caused by various human and natural sources. Excess fertilizer and other pollutants are causing large algae blooms in lakes. The main sources of pollution are point sources like factories and non-point sources like agricultural runoff. While industries and agriculture are major contributors, domestic waste and individual behaviors also significantly impact water quality. Proper wastewater treatment can remove many pollutants but emerging contaminants like pharmaceuticals remain a concern. Preventing pollution requires conservation, responsible chemical use, and maintaining stormwater infrastructure. Addressing water issues will require awareness, education, sustainable practices, and global cooperation.
This document discusses various aspects of water resources including:
1) Water is essential for life but only 3% of Earth's water is freshwater, with the majority being saltwater in oceans.
2) Freshwater sources include lakes, rivers, streams, groundwater and ice/snow, with only 1% of total water accessible for human and agricultural use.
3) The water cycle describes the continuous movement of water above, on, and below the Earth's surface through different states of matter and is driven by the sun's energy.
This document provides notes on ecosystems compiled by Dr. G Subbarao for environmental science students. It defines key ecosystem concepts like producers, consumers, decomposers, food chains, and food webs. It also explains ecological pyramids and how they illustrate the transfer of energy and biomass between trophic levels. Examples are given of various natural ecosystems like forests, grasslands, ponds, and oceans. Energy flow through ecosystems is described, with the sun as the main source of energy and photosynthesis enabling its transfer and transformation through food webs.
The Narmada Bachao Andolan was a social movement opposed to large dams being built on the Narmada River in India, including the Sardar Sarovar Dam in Gujarat. Led by activists Medha Patkar and Baba Amte, NBA organized protests like hunger strikes and a march to raise awareness about the environmental and social impacts of displacement. While the Supreme Court initially stopped dam construction, it later ruled in favor of the project subject to rehabilitation conditions. However, the movement successfully increased scrutiny of resettlement plans and environmental compliance for large dam projects in India.

On Earth water has too many forms and variety which
are necessary specifically for particular geographical as well as
environmental surroundings. Below 1% of the world's fresh
water (0.007% of all water on earth) is reachable for direct
human uses. Water pollutions now become a part of concern and
disquiet in country like India. Large parts of water which are life
supportive get contaminated because of illegal activities of human
beings. Water effluence is a major problem globally. It is the
leading worldwide cause of deaths and diseases, and that it
accounts for the deaths of more than 14,000 people daily. In
addition to the acute problems of different problems in
developing countries, industrialized countries continue to
struggle with water pollution problems as well. There are many
inorganic metals which are contaminating water bodies which
serve life to large part of India, Arsenic (As) is one of the biggest
threats for water bodies. High toxicity of Arsenic poses a serious
risk not only to ecological systems but also for human health.
There is availability of sophisticated techniques for arsenic
removal from contaminated water, development of new
laboratory based techniques along with cost reduction and
enhancement of conventional techniques are essential for the
benefit of common people. This paper is based on the future
aspects, for removal of Arsenic from drinking water or the water
of different rivers like Ganga, Gomti and Yamuna etc which
humans are consuming for domestic purpose. Demograph
estimate that around 52 millions peoples are drinking ground
water with arsenic concentrations above the guidelines of World
Health Organization. WHO proposed a parameter or MIC for
Arsenic i.e. of 10 parts per billion (ppb) or 0.010 Mg/L, it is found
that level of Arsenic has been increased vigorously in many
rivers. Objective is to apply Bioremediation technique with the
help of batch culture that needs Bioremediators to detoxify
contaminated water and helps in maintaining the original quality
of water.
IN DEFENSE OF THE RATIONAL USE OF WATER, A SOURCE OF LIFE, ON WORLD WATER DAY...Faga1939
This article aims to highlight the importance of water for life on planet Earth, present how water emerged on our planet and demonstrate the lack of rationality in the use of water for its various purposes on planet Earth. Research carried out by the São Paulo State University (Unesp), Guaratinguetá campus, in collaboration with the Federal Technological University of Paraná (UTFPR) and the Astrobiology Institute of the North American space agency (NASA), considered that existing water on planet Earth would have become originated from comets (30%), asteroids (50%) and the solar nebula (20%) that collided with Earth. Around 800 million people do not have access to drinking water around the world, 2.5 billion people do not have basic sanitation and, between 3 billion and 4 billion people, which corresponds to half of the world's population, do not have access to water on a permanent basis using water of questionable quality every day and 11% of the world's population still shares water with animals in riverbeds. According to the WHO (World Health Organization), seven people die every minute in the world from drinking rotten water and more than 1 billion people still defecate in the open. The OECD (Organization for Economic Cooperation and Development) reports that global water demand will increase by 55% by 2050. The forecast is that this year, 2.3 billion additional people – more than 40% of the world's population – will not have access to water if adequate measures are not adopted. Therefore, we have nothing to celebrate on World Water Day.
1) The document discusses various types of environmental pollution including air, water, soil, and focuses on pollution of Dal Lake.
2) Rapid industrialization and modern civilization have led to air pollution through emission of dust, smoke and toxic gases, deteriorating air quality in urban areas.
3) Water pollution occurs when sewage and industrial effluents are disposed into water bodies like rivers. Soil pollution is caused by disposal of solid wastes from homes and industries.
4) Dal Lake in Kashmir was once clear and large but is now severely polluted due to waste from nearby houses, hotels and encroachment, threatening its beauty and tourism if preventative measures are not taken.
Water is facing a crisis today.
Water scarcity affects all social and economic sectors.
Water footprint measures the consumption and contamination of freshwater resources.
This document discusses the issue of water pollution and its causes. It notes that as the human population grows, we are putting increasing pressure on water resources and reducing their quality through pollution. Water pollution comes from many sources, both from direct discharges called point sources like factories, as well as more scattered nonpoint sources. Some of the major causes of water pollution discussed include sewage, excess nutrients from fertilizers and sewage that can cause algal blooms, toxic chemicals from industrial waste and chemicals like heavy metals, and other pollutants that enter water sources from everyday products. Proper treatment and regulation is needed to address this serious and widespread problem.

The successful of pregnancy in humans and rodents occur between the interaction maternal and fetal
interface, specially involving the participation of uNK cells. This interaction involved neo angiogenesis,
placentation and presence of mediators like nitric oxide. During the pregnancy the administration of LPS
in the dams can results in necrosis, preterm birth, IUGR, miscarriage or neurological problem. Once the
uNK cells are activated, they can produce vasodilators, like NO. So, the main purpose of this study was
to evaluate if LPS cause alteration in the uNK cells in pregnant mice and if the same behaviour can be
detected by NO in the blood. Also we evaluated the effect of LPS to cause neurological injuries. To do that
we used pregnant mice on gd 10th and those was treated with LPS for different times. Uterine samples
were collected at 0.5,1,2 and 6hr after LPS treated and processed for paraffin embedding and tissue
homogenate. The samples designated for paraffin embedding was performed the Dolichos biflorus (DBA)
lectin cytochemistry and anti-iNOS immunocytochemistry. The samples designated to tissue homogenates
were processed for SDS-PAGE and Western-blot using anti-iNOS and evaluate of NO concentration. We
found after 2h LPS exposure the mice showed fever and low capacity to explore different environment.
At the same time, we found increase in the nitrate/nitrito ratio in a dose dependent manner in the uterus
after 2h LPS exposure.

Growth Factors in the Human Body: A Conceptual Update_Crimson PublishersCrimsonpublishersCJMI
Growth factors are signaling molecules that stimulate cell growth, proliferation, and differentiation. They were originally discovered through their effects on cell and tissue growth in culture. Growth factors act through paracrine, autocrine, or endocrine signaling and can be divided into families based on their structure and function. Some major growth factor families include transforming growth factor beta (TGF-β) and insulin-like growth factor. Growth factors play roles in processes like wound healing but can also contribute to diseases such as cancer, diabetes, and liver fibrosis when their regulation is abnormal.

This document discusses the importance of an integrated research approach for developing microalgae fuels. It notes that interest in microalgae fuels has fluctuated with oil prices over time. While some technological advances have been made in individual stages of biomass production and processing, an integrated approach considering all stages together from strain selection to fuel conversion is needed to make the whole process economical. Each step in the process depends on and provides feedback to influence other steps. An integrated and continued research effort is required to generate realistic economic assessments for commercial scale microalgae fuel production.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
