Sooo this is something I found from this website:
http://www.sustainabletable.org/ I never really understood the exacts of sustainable food, but I think this wesbite really explains a lot of it and I think everyone should take the time to at least read a little bit of it. Without coming right out and saying it, I think a lot of the issues it talks about are the same ones that some vegetarians talk about when making the choice to become a vegetarian, for example the environment and humanity to animals. I think though that its interesting to see all the ways we can change these things with out having to give up our precious meat ^_^
