" I do wonder if livestock pressure from animals that aren't carefully managed (because I wonder if you're worried about where tomorrow's breakfast is going to come from, are you going to have time to be like, "Oh, I need to think about sustainable livestock management") could be detrimental in the long term, but I hope many communities have the wisdom to avoid those kinds of problems. "
From what I remember reading about them last December was that they don't just drop off animals, they teach the
local people how to manage them in a farming system. For instance, get a cow. Use the
milk, use the manure from the cow to fertilize garden plots. The cow has a calf, raise the calf,etc.
I've seen a few negative reviews regarding Heifer where money donated is not used specifically as requested (you donate for a calf, they sometimes use money for goats,etc)
In any case this is the only charity I know of that seems to follow a similar track to the philosophy of
permaculture where people in need can use a starting "seed" of donation and education that sustainably keeps them out of poverty through their own efforts and capabilities (IE teach a man to fish..) . I'm not sure how selling trinkets and and such would fit that philosophy unless possibly they were making the jewlery and clothing themselves from locally sourced materials,etc.
