I absolutely agree that sourcing locally is a great thing but please don't claim that it will end global warming. Remember that to have a huge effect things need to be sourced very locally, like within 50 miles which isn't really practical in a country the size of the US.
Then the human race needs to stop travelling vast distances in vast numbers, eating so much meat, driving everywhere, waiting huge amounts of energy at home and at work unless its produced by renewable sources.
Buying local is one part of a huge web, its a positive but its not the total answer.
Unless I've completely misread this and there is a healthy dose of sarcasm involved that I missed.
