Although there were several existing laws that dealt directly or indirectly with environmental issues it was necessary to have a general legislation for environmental protection because the existing laws focused on very specific types of pollution, or specific categories of hazardous substances or were indirectly related to the environment through laws that control land use, protect our National Parks and Sanctuaries and our wildlife. Thus there was a need for an authority which could assume the lead role for studying, planning and implementing long term requirements of environmental safety and give directions to, as well as coordinate a system of speedy and ad...

  What is meant by Global Warming? The increasing of temperature at atmosphere is called as Global Warming or green house effect. The pollutants responsible for global warming are CO2, CH4, CFC’s, O3 water vapours. Among these pollutants, CO2 has much effect. The gases absorb more light from the sunlight. Hence the temperature increases by 1oC. The planet earth is in serious jeopardy due to global warming. The polar ice caps are melting at an astonishing rate. Severe flooding and droughts are creating havoc around the world. All nations must begin to address, formulate, and implement the necessary solutions to reduce global warming before it becomes irreversible. Developed countries can drastically reduce the emission of green house gasses (GHG) which are destroying the ozone layer by reducing the destruction of rainforests, switching from electric generating power plants that are burning fossil fuels, to electricity generated by wind technology, and reducing the amount of carbo...

  Introduction : According to ODUM (1971), Pollution is “an undesirable change in the characteristics of air, water and land that harmfully affect the life and also create health hazards for all living organisms on the globe”. According to SOUTHWICK (1976), Pollution can be defined as “the unfavorable (or) alteration of environment caused by human activities and causing harm to human beings”. Basically the Pollution is of two types. (1) Natural Pollution : This type of pollution is limited in its occurrence generally from natural hazards like volcanic eruptions, emissions of natural gas, soil erosion, ultraviolet rays, cosmic rays etc and (2) Manmade Pollution : Most of the pollution is man made only. However, Pollution is usually categorized as Air Pollution; Water Pollution, Thermal Pollution; Noise Pollution; Land & soil Pollution; Radio Active Pollution and Marine Pollution.
