Should all polluting activities be banned? Could pollution ever be justified? Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. The major polluting activities in our world are power stations, industries, cars, CFC gases in aerosols, refrigirators and manufacture of polystyrene. To protect the environment from the adverse effects of pollution, many nations worldwide have enacted legislation to regulate various types of pollution as well as to mitigate the adverse effects of pollution. Prevention of Acid rain is very important for the future of our environment. Since acid rain is caused mainly by the emission of sulphur dioxide from coal-fired power plants. There are a number of preventions, including: switching fuel sources to natural gas, oil, or renewable energy sources; switching to low-sulphur coal; removing the sulphur from the coal before burning; using fluidised-bed combustion processes to burn the coal; and removing the sulphur from the smoke stack after combustion through the installation of pollution control equipment. Other prevention methods are catalytic converters, road traffic restrictions, and equalising acidity in affected water systems by using powdered limestone and reduction in the sulphur content of fuels. Things you could do in the community to prevent are protest against the use of coal fire in industry, walking more and driving less, buy fuel efficient cars or alternative fuel powered vehicles and head community campaigns promoting awareness of the issue. Nuclear safety covers the actions taken to prevent nuclear and radiation accidents or to limit their consequences. The nuclear power industry has improved the safety and performance of reactors, and has proposed new safer (but generally untested) reactor designs...
