Try this simple test. Stretch your arms out. Make a fist with each hand and bring them quickly together. If your head got in the way, you are accident-prone. No, don't try it again, stop it. We are going to discuss safety. I said stop it! Look at figure 1.
Figure 1 is a specimen of Modern Man. Norma found it in our yard. She took a picture of it. She made it carry out a little bag of garbage. There is an old banana in there, some bones, paper --organic things-- in a plastic bag. Plastics are organic polymers derived from oil. Oil comes from geologically compressed zooplankton and algae. If anything was to cause something to fall off of (or out of) the bag or out of the Modern Man in figure 1, a close examination would reveal this:
This brings us to thoroughfares. Our specimen of Modern Man must cross a lane to throw garbage in a can. This is asking for trouble. Lanes, freeways, doesn't matter --they are all roads. We have seen what happens to skunks when they try to cross roads. Modern Man shares 99% of DNA with Mephitidae and that constitutes certainty in all rational disciplines. If skunks can't reliably cross roads, free from accident, neither can Man. Barring genetic engineering away from accident-proneness, there is only one solution. We must redesign our environment so that everything --workplaces, residences, churches, tallow works, skyscrapers, farms, markets, missile silos and liquor stores-- everything we need in life, is on one side of the road --all roads, all over the world.
I can't imagine what would be on the other side of the road then, can you?
