The need for unpolluted air is becoming more and more a necessity in our communities. Clean air, free of contaminants that are mixed with the air or to particles suspended in the air is needed by everybody including animals. Unclean air or polluted air is the effect of hazardous substances released into the air. They come from automobile exhausts, landfills, explosions and fires, factory leaks and even commercial products that we use at home. Contaminants also come from the surface soil that is blown around by the wind.

Concerned groups are frantically trying to lessen the impact of these pollutants. Automobile manufacturers are turning to electricity to run their engines rather than using carbon fuels. Factories are trying to convert to raw materials that will not generate pollutants. They also recycle as much as they can and treat waste waters. Responsible people are trying their best to lessen air pollution but it seems that it will take some time before the problem can offer a solution that will positively affect a greater magnitude of the population.
