Ecuador is voting on a new constitution this weekend that, among many other things, would give Nature legal rights and allow citizens to sue on its behalf -- and the President is threatening to quit if it doesn't pass. Due to ignorance, I can't really judge this in the context of Ecuador (although 444 articles seems like way too many to me for a constitution), but it leads me to wonder if there's a Nature amendment movement in the U.S. -- not that it would have any political traction.
