2 ways to minimize air pollution?

Answer 1

2 general ways are to avoid emitting things that will be pollutants and promoting things, like trees, that will help remove pollutants. To avoid emitting pollutants you can optimize processes to have lower emissions of everything including pollutants, remove the pollutants before releasing (like filters and scrubbing towers), process the emissions to change them (like catalytic converters), change to processes that do not emit pollutants.
