I relatively new to the whole permculture thing, but I'm a diffident believer. I cam a cross this Ted Talk that would make anyone consider what the put in their mouth that's food.

Just thought i'd share it with you all. I live in ag-country so this hit really close to home, as in one of the frogs tested came from a irragation ditch less than 10 miles from my house. How can you live in a environmental responsible way and have a healthy
permaculture farm if your neighbors are toxifying the ground and
water? I'm looking in to moving but where is safe?
I hope spreading the news and raising awareness will help.
