All the bad scenarios are things to avoid, things to work to prevent.  I just personally see a future of more and more people, managing to live in tighter and tighter conditions, with less and less of a natural world to enjoy ... to be very sad.

I went to the beach today with my nephew, and then we went for a hike through the park and over the river, finally playing frisbee on a green lawn.

I'd like that to be possible 10 generations from now.
