This act has been faced by many criticisms but at the same time the environmentalists have deemed it necessary for reducing global warming. In this paper we shall discuss the pros and cons of this EPA policy and its impact on the environment as well as its social impacts. The burning of fossil fuels like coal and oil, has led to emission of greenhouses in excessive amounts. Although the green house is essential for our survival as it keeps the earth surface warmer but release of excessive gasses in the atmosphere will increase the temperature of the Earth’s surface from 3.2 to 7.2?F above 1990 levels by the end of this century. This will not have an adverse effect on the environment but will also badly affect people, plants and animals. The Federal government of U.S is continuously working towards its aim to stop global warming. Many measures are been taken by them, one of which is reduce the emissions of CO2 by the coal power plants and encouraging the use of natural gas for power plants. These measures are definitely necessary for preserving the environment. It will save thousands of lives from various diseases- heart and lung diseases, malaria, smog diseases, chronic bronchitis, asthma, severe coughs and so on. Our children will grow up as healthier individuals without having to face the diseases in their childhood. Furthermore it will restore back the nature to its original form.
