Science and technology are what we can do; morality is what we agree we should or should not do.

If religion and science could be united on the common ground of biological conservation, the problem would be soon solved. If there is any moral precept shared by people of all beliefs, it is that we owe ourselves and future generations a beautiful, rich, and healthful environment.

We use pandas and eagles and things. I'd love to see a wilderness society with an angry-looking wolverine as their logo.
