most things ruin the environment.

If you seriously believe in doing everything you can for the environment you would need to stop most forms of media, and if you do that then that is highly commendable.
Realistically, I imagine most ppl wouldn't.

The way I see it, just try to make positive changes to your life, which you are able to, that will help the environment. eat less meat, buy 2nd hand hardware if possible, game less, use less water etc etc.

Or maybe I am wrong, that is just my thoughts on the subject.
