Dr. Hotton holds that we must now "share the planet with a fellow civilized species." He bolsters his argument with hearsay evidence of "raccoon culture" that to me seems rather flimsy. The woven strips of bark known as "raccoon wampum" are impressive examples of animal dexterity, but to my mind it remains to be proven that they are actually "money." And their so-called "pictographs" seem little more than random daubings. The fact remains that the raccoon population continues to rise exponentially, with raccoon bitches whelping massive litters every spring. Dr. Hotton, in a footnote, suggests that we can relieve crowding pressure by increasing the human presence in outer space. This seems a farfetched and unsatisfactory scheme.
