If I tell computer users it’s very likely their hard drives could die any second and they should back up their files, it’s a good thing they backed up their precious files, even if their hard drives don’t die that instant. And, actually, the hard drives very well could die.

The fact remains that the earth has some unrenewable resources, the world population is increasing, and cars do pollute the air (regardless of to what degree that affects climate change).

Few people would agree to standing behind an idling car’s exhaust pipe for an hour a day, given the choice not to. They know it’s not healthy for them. Why would it be healthy for the earth, then?

Cutting down on pollution, conserving resources – these are good practices, regardless of what you believe about humans’ effect on climate change.
