What an interesting thread...wish I had more time to compose this, but here are some thoughts...
1. Alternative Theory for Source of Non-native breeding populations in Florida. Remember Andrew? Charley? How about Francis aor Jeanne? Not ringing a bell? How about Katrina? Each of these hurricanes unleashed massive destruction on Florida, destroying homes, zoos, "snake farms", wildlife parks and the like. How many non-native critters escaped and were never recaptured?
2. Democracy at Work...Or Not? Contrary to popular belief, the USA is not a "Pure" Democracy, we are a Representative Republic. We elect Representative, who represent our intrests (at least in theory). This prevents a "dictatorship by the mob" which is what happens with pure democracy.
3. Nature Shows, Unspoiled Environments, Bad Science, and The Media. The idea that somewhere out there is the "Unspoilt Place - Untouched by Man" is utopian nonesense. We can no more prevent human impact on the environment then we can uninvent computers or automobiles. The unpleasent facts that no one wants to know are this:
A. 99.999 percent of all species that have ever existed are now extinct, 99.999 percent of all species that now exist will become extinct in the future. This likely includes Homo sapiens.
B. The number of species actually driven to extinction by humans is pitifully small and insignificant compared to those driven to extinction by Nature. We have wipped out Passenger Pidgeons, Dodo Birds, Tasmanian Tigers, and few others. We could theoretically wipe out most of the large mamels, birds, fish, reptiels and amphibians. This is a drop in the bucket. In fact, when it really counts, we are powerless to wipe out those creatures that we really want to - rats, mice, cockroaches, lice, fleas, mosquitoes, and the deadly diseases they carry -paulge, malaria, yellow fever, etc. You can add feral cats and dogs to that list, as well as introduced pests like Cane Toads and Mongoose.
C. Nature is the Big Killer. 65 Million years ago a Meteor the size of Manhattan wiped out the dinosaurs - the most dominant and successful large land vertebrates ever. At the time of their demise, a species we call Troodon had developed bipedal gait, binocular vision, larger brains, grasping hands,and social living habits. Sound familiar? That's where hominids were a few hundred thousand years ago. Given a little more time its concievable these Troodontids (or somethng like them) could have been where we are today. We are on the verge of being able to prevent large meteor impacts. What if the Troodontids or their kin had done this?
Aren't you glad I didn't have more time to think about this?
Cheers,
John D
