It looks like primal scream therapy. Anyway, it wouldn't be any weirder than a religion that had people babbling in tongues or drinking the blood of its god.

Hey, I am one of thoes people!

no just kidding. in my opinion its just people who can't handle the loss of life? i understand having affection for trees, and not wanting them to be taken down, but if obsessing over it that much creates pain in your own life its gone way to far.

Sorry but I don't see where one video shows "eco-religion". Personally, I wouldn't want to hang out with that group. While I can understand their feelings, their expressions are a bit over the top. I love nature but I think folks like these are doing this for selfish reasons; "hey! Look at me! I feel so DEEPLY..........!" Gawd.
I would be interested in knowing more about eco-religion, I thought that was what the Man-made Global Warming cult was about.
