People can get really worked up about trees:

They're
putting a new sports facility on campus in Berkeley and the radical greens, er, whites, er...anyway, are putting up quite a protest. Oddly enough if you look at pictures of the East Bay from a hundred years ago or more, its amazing: no trees there:

Now its completely covered with trees except for the houses.
And of course there's these "weeds" called Eucalyptus that invaded California from Australia (and you Aussies claim not to be imperialist!)....Gross!
I like trees, but trees are not universally good....
