Real biologists who actually do the research will tell you that they almost never find a phenomenon, no matter how odd or irrelevant it looks when they first see it, that doesn't prove to serve a function. The outcome itself may be due to small accidents of evolution.

The solutions like freezing zygotes, fertilized eggs, of all kinds of animals and so on, or keeping them in zoos and having arboreta where we have trees, all these things have been promoted. Even getting the complete genetic code of various fishes so we can let them pass away and then we'll pull them back. That is science fiction run amok.

I like what Abba Eban once said during the 1967 war. He said, "When all else fails, men turn to reason."

Most people are surprised when they hear my somber figures: we know of 2 million species of plants, animals and microorganisms, and we can give them each a scientific name and a diagnostic description. We know, perhaps generously, more than just a little bit of the anatomy in no more than 10 percent. We have done thorough studies in fewer than one-tenth of 1 percent. And the total number of species on Earth is unknown to the nearest order of magnitude.

The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.

Companies that are willing to share, to withhold in order to further the growth of the company, willing to try to get a better atmosphere through a demonstration of democratic principles, fairness and cooperation, a better product, those will win in the end.

I had in mind a message, although I hope it doesn't intrude too badly, persuading Americans, and especially Southerners, of the critical importance of land and our vanishing natural environment and wildlife.
