Notes

"When the aliens came down, with their limitless energy machines and their limitless food machines, and told us they would give us all their technology if we would only promise to listen and heed the sad tale of the home world they so nearly destroyed with a juvenile civilization's ignorance at what terrible damage to nature can be wrought from a thoughtless use of technology, well, the environmentalists down here on Earth became a bunch of insufferable know-it-alls."
