Paper Waste

Over the past few months I have worked on several freelance projects. I'm constantly aware of how much paper and ink is used printing proofs, etc. out. Not to mention final products. I'm trying to make a conscious effort not to print anything unnecessarily. Some things you obviously can't avoid printing. But certainly multiple copies of the same thing (but with minor tweaks) isn't worth it. Now I'm on to saving my files on something other than my hard drive. As I'm staring at the stack of DVD+Rs that my ancient desktop computer won't burn to, I'm thinking an external hard drive might be worth the price...
