ENVIRONMENTAL STUDIES

Global warming ENVIRONMENTAL STUDIES Environmental studies is the academic field which systematically studies human interaction with the environment.While distinct from ecology and environmental science, the field encompasses study in the basic principles of those two fields of learning as well as the associated subjects, such as: ethics, policy, politics, law, economics, philosophy, sociology and other social aspects, planning, pollution control, natural resources, and the interactions of human beings and nature. Ecosystem Structure and Function The study of ecosystems mainly consists of the study of the processes that link the leaving organism or in other words biotic component to the non-living organism or abiotic component. So for the study of environment we should aware with biotic and abiotic component

Natural Resource Conservation Focus on managing and maintenance of forests which are natural resources and for the maintenance of wildlife forms. It is also a scope of environmental studies. Environmental Pollution Control With the knowledge of environmental science, everybody can control the pollution. He/she can handle the waste management and also look for ways to control pollution on the aspect of pollution control. Environmental Management There are several independent environmental consultants who are working with Central and State pollution control Board. They offer advice to solve the problems of environment, the optimum solution for the upcoming problems. They give direction for controlling pollution due to industrial development. There are several current consultants who are working with government pollution control boobs, involved in policy making, pollution control, maintenance of ecological balance. Social Development NGO (nongovernmental organizations) help in creating awareness regarding the protection of the environment and making the masses aware of various environmental issues . They also generate a public opinion in this field. They work towards disseminating information and in bringing about changes in political policies. The social dimension of this profession includes controlling population explosion through organizing advisory awareness camps. Importance of Environmental Studies Environmental studies helps to maintain ecological balance by providing a basic knowledge of environmental systems and their processes. This study help us by giving information regarding the changes that take place due to anthropogenic factors environmentally.

It also helps to gain a skill in using techniques to analyze various environmental systems and the effect of human activities on that system. - Environmental studies applies economical methods and concepts to issues of the environment, management, environmental policy analysis. Environmental study includes diverse area such as property rights, economic instruments for pollution control, cost benefit analysis management applications with environmental policy. - Concepts from environmental studies can be applied to the study of agriculture and the design of sustainable production systems. - We need a study of physical, biological, chemical and social processes that form the basic of the problem of environment. Environmental studies provides skills necessary to raise the questions and too often obtain answers to some of the environmental problems which our planet is facing today. As the world's population grows, improving living standards without destroying the Environment is a Global challenge. Most developing countries with rapid population growth face the urgent need to improve living standards. As we exploit the nature to meet the present needs, we are destroying the resources needed for the future. Threat to Environment In the past decade in every environmental sector, conditions have either failed to improve, or they are worsening. Public Health  Unclean water along with poor sanitation, kills over 12 million people each year. Water pollution is a serious problem everywhere.  Air pollution kills nearly 3 million people. Air pollution, already a serious problem in cities, is becoming worse as urban population grow and the number of motor vehicles rises.  Heavy metals and other contaminants also causes health problems Food Supply  In most developing countries, the population has been growing faster than food supplies.  Population pressures have degraded some 2 billion hectares of cultivable land- an area the size of USA and Canada put together. Freshwater  Supply of fresh water is limiting, since the demand is soaring as population grows and per-capita use rises.  By 2025, when world population is projected to be 8 billion, nearly 48 countries containing 3 billion people will face freshwater shortages Coastlines and Oceans  Half of all coastal ecosystems are pressured by high population densities and urban development  A tide of pollution is rising in the world's seas  Ocean fisheries are being overexploited and fish catches are down Forests  Nearly half of the world's original forest cover has been lost.  Each year millions of hectares of forests are cut, bulldozed or burned  Forests provide over 400 billion US$ to the world economy annually and are vital to maintaining healthy ecosystems  Current demand for forest products may exceed the limit of sustainable consumption by 25% Bio-diversity  Earth's biological diversity is crucial to the continued vitality of Agriculture and Medicine, and perhaps even to life on Earth itself  Human activities are pushing many thousands of plant and animal Species into extinction  Two of every three species is estimated to be in decline Global climate change The Earth's surface is warming due to greenhouse gas emissions, largely from burning fossil fuels.  If the global temperature rises as projected, sea levels would rise by several meters, causing widespread flooding.  Global warming also cause droughts and disrupt agriculture Environmental protection is a practice of protecting the environment, on individual, organizational or governmental level, for the benefit of the natural environment and (or) humans. Due to the pressures of population and our technology the biophysical environment is being degraded, sometimes permanently. This has been recognized and governments began placing restraints on activities that caused environmental degradation. Since the 1960s activism by the environmental movement has created awareness of the various environmental issues. There is not a full agreement on the extent of the environmental impact of human activity and protection measures are occasionally criticized. Academic institutions now offer courses such as environmental studies, environmental management and environmental engineering that study the history and methods of environmental protection. Protection of the environment is needed from various human activities. Waste, pollution, loss of biodiversity, and the introduction of invasive species are some of the issues relating to environmental protection. Ground breaking wave connect energy STORY OF A TREE TO A MAN PRAYING FOR A BOON I need no introduction, yet I have to mention my name, yes I am a tree, the embodiment of total sacrifice to the humanity in particular and the whole world in general. “Do you think that my sacrifices are recognized and rewarded.” ..?
