The environmental thing is there, but I don't worry about it too much. I recycle everything I can, including articles I print out and don't need anymore, ink jet cartridges etc. and trees are a renewable resource.
I try to be environmentally friendly, but there are some things I'm not willing to give up for that sake. I love my physical copies for work, so I'm going to keep them. I hate being hot or cold, so I'm going to keep my thermostat where I'm comfortable etc.
But I'll do other things such as recycle, not buy bottled water, changed to totally CFL light bulbs, drive fuel efficient cars.
Everyone should care, but everyone has limits on what they're willing to give up for the environment's sake, and I do better than most.
