Environmental pollution is a term that refers to all the ways by which people pollute their surroundings. People dirty the air with gases and smoke‚ poison the water with chemicals and other substances‚ and damage the soil with too many fertilizers and pesticides: People also pollute their surroundings in various other ways. For example‚ they ruin natural beauty by scattering junk and litter on the land and in the water. They operate machines and motor vehicles that fill the air with disturbing noise

Doctors and researchers have uncovered several diseases that seem to be caused by air pollution‚ including asthma‚ lung cancer and heart diseases. Along with harming human health‚ air pollution can cause a variety of environmental effects‚ e.g. acid rain‚ ozone depletion‚ crop and forest damage and global climate change. There are now various air pollution control technologies and strategies available to help reduce it‚ People are encouraged now more than ever before to use non-polluting renewable

AIR POLLUTION When we hear about pollution‚ we think of smog‚ traffic congestion‚ acid rain‚ and other pollutant-related terms. However‚ we also need to consider contaminants in the air we breathe and chemical pollutants around us. We need to be concerned about indoor air because it can affect the health‚ comfort‚ and productivity of workers. POLLUTANTS AND CONTAMINANTS Chemical pollutants include tobacco smoke and chemical spills. Particles include pollutants such as dust and dirt from drywall

changes would have drastic negative effects on the economy. He then presents his way of thinking on the subject‚ which is in conjunction with efforts taken to correct previous air pollution issues. Easterbrook points out that the urban fog and acid rain were thought to be as insurmountable as the current greenhouse gas issues. Through strict regulations the air pollution was decreased and the damage corrected. In both of these cases the measures proved to be cheaper than expected. He points
