9. The Nature Conservancy The Nature Conservancy is a leading conservation organization working around the world to protect ecologically important lands and waters. Working to preserve ecosystems and avoid flora and fauna extinction, the Nature Conservancy is like a great, big, wonderful tree-hugger.
10. World Wildlife Fund The WWF protects endangered animals in remote locations and extreme eco systems (like the Galapagos Islands or Borneo). You cannot look at that sweet panda face on their logo and not kick in a few bucks.
