Very cool Tree science video #1

[brookpederson]

Not exactly any chainsaws or felling or idiots in these vids. But they are incredibly interesting if your into how cool tree's are!! The host is kind of arrogant but the science behind trees is amazing.

Thanks for posting. We were just having a discussion about this and my friend suggested that tall trees get their water or moisture from precipitation. I thought this would be hard to believe because of lack moisture at that height. Sun rays would then attribute to the lost of moisture being the tallest trees around.
