All ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts.

If in a city we had six vacant lots available to the youngsters of a certain neighborhood for playing ball, it might be "development" to build houses on the first, and the second, and the third, and the fourth, and even the fifth, but when we build houses on the last one, we forget what houses are for.

The rich diversity of the world's cultures reflects a corresponding diversity in the wilds that gave them birth.

Third, there is value in any experience that exercises those ethical restraints collectively called 'sportsmanship'. Our tools for the pursuit of wildlife improve faster than we do, and sportsmanship is the voluntary limitation in the use of these armaments. It is aimed to augment the role of skill and shrink the role of Gadgets in the pursuit of wild things.

The last word in ignorance is the man who says of an animal or plant: 'What good is it?

That land is a community is the basic concept of ecology, but that land is to be loved and respected is an extension of ethics.

We all strive for safety, prosperity, comfort, long life, and dullness. The deer strives with his supple legs, the cowman with trap and poison, the statesman with pen, the most of us with machines, votes, and dollars. A measure of success in this is all well enough, and perhaps is a requisite to objective thinking, but too much safety seems to yield only danger in the long run. Perhaps this is behind Thoreau's dictum: In wilderness is the salvation of the world. Perhaps this is the hidden meaning in the howl of the wolf, long known among mountains, but seldom perceived among men.
