eco - free food?

I know, I know, I know! I've been so slack on envrionmental/going green posts here on method lust! What's the deal'e'oh, yo?! Well, here you go! I just found this today and my eyes, they were'a opened! People (with plenty of income) going grocery store dumpster diving for free groceries, all in order to live more simply, and environmentally friendly (including stopping unnecessary waste.) I'm really curious what your thoughts are here! Could you do this? Do you do this? Don't be shy - share!
