Frank J has some interesting observations on trees:

Tom M. from Pyay, Myanmar asks:
If a tree falls in the woods and crushes some tree hugging hippies would they still like the tree’s so much?

Great question. I’ve often wanted to say to some tree huggers blabbing on about how great nature is, “I hate trees.”

Then when they ask, “How can you hate trees?”

I’d say, “A tree killed my father,” just to see their reactions.

Trees are dangerous creatures. Frequently they like to take others in their deaths, toppling on to man and woodland creature alike. They also are the only other creature than man to use fire to kill; there would never be forest fires if it weren’t for trees. And accidentally running off the road would not be such a hazard if it weren’t for all the unforgiving trees that constantly line them.

That’s why I hate trees, and I would like to think that God, in His infinite wisdom, would grant some sense to the hippy at the moment just before the tree hits him. Then his last thought would be, “Damn you, trees!” before the massive creature crushed his skull in its dying fury.

There is also a lot of non-tree material on the site.
