I strongly support conservation organizations that work with and support surrounding human communities. These communities are integral to protection of the environment and its animal inhabitants. It's important to understand that environmental degradation is often tied to poor people simply trying to survive. Treating them as villains only creates enemies and alienates them. It's the local people who are the strongest advocates and most effective guardians of these wild areas. They are also the most logical.
Here's an example...the Dian Fossey Gorilla Fund "Coins for Congo" program. These guys are a great group and I've been a member for several years. The mountain gorillas have a special place in my heart (awwwwww!)
