Deep Ecology

I am a Junior majoring in History and was assigned Ishmael as reading for my geology class. It is one of the most amazing books I have ever read. I too, feel the exact same way about what we are doing to the planet. However, i feel totally overwhelmed at the task of doing something about it, especially in the US, where it’s almost trendy to convert the earth into a playground for the rich and affluent, and screw anyone or anything else that gets in its way. . . . I don’t think joining Greenpeace or Earth First! is doing enough, do you? Who or what can you get involved with that will make people listen?????? Or maybe I’m not getting the point of Ishmael after all. I don’t know. Just the same, things need to change. But how?
