None.
Hydro Chloro Fluorocarbons are the alternate to CFC's. They cause much less pollution and ozone depletion than the latter.
Yes, they do have but only a little much. Ozone and air pollution might be indirectly related.
Risk factors for air pollution include proximity to industrial areas or highways, high population density, weather conditions that trap pollutants (such as temperature inversions), and inefficient waste disposal practices. Individuals with pre-existing respiratory conditions, the elderly, and children are also at higher risk for health effects from air pollution.
Politicians will survive, much as the cockroach has survived for hundreds of millions of years. Politicians rarely mouth anything about ozone layer depletion, because their constituents with money speak much louder.

yes.
Electromagnetic waves only cause sound pollution because they are sound waves.
Talking too much could be considered noise pollution, but that's about it.
Automobiles, burning of matter and using of natural resources at an exploiting level cause much pollution.
Air pollution is caused when too much oxygen is emmitted into the air. This damages the ozone layer and is thought to be the reason of the hole in the ozone layer. The ozone layer protects us from the sun's harmfull rays. If air pollution continues at this rate, we might see a large skin cancer epidemic in the future. Oxygen is mostly emmited through cars.
If you put pollution in a box it is 2 litres
