Adopt a forest

My advice to aspiring conservationists is this: find yourself an imperiled patch of the earth, as Ghillean Prance and Guido Berguido have done. Tend it, defend it, make it your own—if only in spirit. Forge alliances, build bridges, encourage others to share your vision. Do not expect it to be easy; it would not be. But by adopting a forest, you just might create a lasting legacy.
