1. Air pollution is a problem because it can cause damage to animals, trees, plants, crops and water sources in the environment. Pollution in the air causes problems for aviation because it reduces visibility, while also being responsible for damaging buildings and other structures.
2. The air we breathe has a very exact chemical composition; 99 percent of it is made up of nitrogen, oxygen, water vapor and inert gases. Air pollution occurs when things that aren't normally there are added to the air. A common type of air pollutionhappens when people release particles into the air from burning fuels.
3. Pollution prevention (P2) is any practice that reduces, eliminates, or prevents pollution at its source. ... Reducing the amount of pollution produced means less waste to control, treat, or dispose of. Less pollution means less hazards posed to public health and the environment.
