  7. What is Environment ? • Natural world • Surrounding in which we live • Life sustaining system in which various living and non-living things are inter-related • Collection of all the external factors or conditions influencing the life of the organisms

  8. Environmental Study: Importance, Scope and Need for public awareness: Our developments are going against nature and environment, Therefore the importance, scope & study of environment has great importance. Our existence depends on the environment, therefore the need for public awareness is of great importance. Importance Of Environmental Studies: Environmental studies provide information about the conditions of environment which could be useful for planning and designing of the project. It provides knowledge about the ecosystems. It provides necessary information about biodiversity. Environmental studies helps to find and solve the big environmental problems. 8

  9. Scope Of The Environmental Studies: To study the interrelationship between biotic and abiotic components. To carry out the impact analysis and environmental audit in order to minimize the environmental problems. Reduce the pollution. Managing the unpredictable disaster. To create awareness to the public. It provides necessary information about biodiversity. Environmental studies helps to find and solve the big environmental problems. 9

  10. Need For Public Awareness: Man has overexploited the natural resource which leads to many environmental problems such as acid rain, ozone layer depletion, green house effect, land slides, cancer and other health problems. Lack of awareness and less number of people participation leads to poor pollution management which are the major reasons for climate instability and unhealthy ecosystem. Hence, it is necessary to create awareness to the public about environmental problems and to protect the environment through implementing proper regulations. In order to protect the environment from the pollution, Supreme court has initiated the environmental awareness to the public through government and non governmental agencies. And it is important duty of us to cooperate with government from our side and work for the protection of environment. 10

  11. Natural Resources: • Resources that occurs in our nature are known as Natural Resources. • These are classifies in two types Renewable & Non-renewable resources. • Renewable Resources : • A renewable resource is a natural resource that can be replenished naturally in the course of time through biological reproduction or other naturally recurring processes. • Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere. • Air, water, sunlight, wind, etc. • Non-Renewable Resources : • Resources that exist in limited supply and can not be replaced if they are used. • Oil, natural gas, coal, Nuclear Fuel, etc. 11

  12. Renewable and non-renewable resources and associated problems : • All energy sources have some impact on our environment. • Fossil fuels — coal, oil, and natural gas — do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

  13. Role of an individual in conservation of natural resources & equitable use of resources for sustainable lifestyles: • Scarcity of resources is the burning problem of modern technology. • The world are using natural resources at a rate faster than the natural processes can replenish it. • It is essential to sustain the natural resources. • We should conserve natural resources so that it may yield sustainable benefit to the present generation while maintaining its potential to meet the needs of the future generation. • There are three specific objectives to conserve resources: • 1. To ensure that any utilization of the ecosystem is sustainable. • 2. To preserve biodiversity and • 3. To maintain essential ecological processes.

  14. Pollution is defined as the excessive discharge of undesirable substances into the environment, adversely altering the natural quality of the environment and causing damage to humans, plants and animals. Water Pollution Soil Pollution Air Pollution 14

  15. What is Air Pollution ? •Perception (When did you last say – Hey, that is air pollution ?) –Visible (smoke, dust, chimney smoke) (Grey Scale) –Odour (petrol, diesel, H2S, bleaching powder) 15
