Replying to Organizations similar to POW?

Wondering if people know of any public interest organizations similar to POW that focus on environmental issues/climate change policies as it relates to outdoor recreation. Just finished law school with a focus on environmental stuff and would love to find some work in this field in a non-attorney job. Feels like it would be a little less depressing than just working for the mainstream environmental groups on litigation against huge corporations that doesn't seem to accomplish much.
