Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which we live. The earth is our home. Unless we preserve the rest of life, as a sacred duty, we will be endangering ourselves by destroying the home in which we evolved, and on which we completely depend.

An individual ant, even though it has a brain about a millionth of a size of a human being's, can learn a maze; the kind we use is a simple rat maze in a laboratory. They can learn it about one-half as fast as a rat.

I doubt that most people with short-term thinking love the natural world enough to save it.

It's always been a dream of mine, of exploring the living world, of classifying all the species and finding out what makes up the biosphere.

The ant world is a tumult, a noisy world of pheromones being passed back and forth.

Thirty trillion dollars worth of services, scot-free to humanity, every year.

When you have seen one ant, one bird, one tree, you have not seen them all.
