I used to be a nature freak, and at some point intend to be again. but I have to admit that I'm not the best steward . . .
I could probably get by w/o air-conditioning my whole house . . . in fact, the inspiration for this thread was my closing the vents in the rooms I don't use. So I'm doing that.
Harder to do is get a new car. My car has a 4 liter engine, which is overkill . . . I live in an area of the country where gas is currently under $2.60, so most of my neighbors/peers have similarly overdone vehicles, which allows me to rationalize.
I eat a lot of red meat . . . cut down some, but I like it too much.
Also socially conscious firms should encourage people to work from home
