But back to the more narrow topic of this thread -- I wanted to say something about Mitigation. Large companies often do this when they cannot avoid a certain amount of pollution (let's say it is CO2 emissions). You would simply plant enough trees to make up for the amount emitted.

A person can do something similar. Lawnmowers (except the Hondas - no surprise) are huge polluters. A modern car (1990's or later) can be driven 100-200 miles and pollute LESS than you mowing your lawn. So, I killed my lawn mower. I use a completely manual reel mower now. A side benfit was I don't have to breather a bunch of dust kicked up by a high speed rotary blade mower.

There are other things the interested person could do. Walk, car pool, or bike to work. You'd get more exercise and probably less stress.
