I'm all for saving the planet but every time someone thinks we are saving tree, water, endanger species, etc... we just end up neglecting something else and the process just shifts attention from one to another instead of actually solving anything.
People thinks they are saving trees, air, etc by going paperless and using more email often forget they are now using more electricity to run their devices to check email, IM, twitter, etc. Where does that electricity come from huh? I'm waiting for someone to claim ebooks will save trees. That would be a good laugh for me!
