What a lonely species we are, searching for signals of life from other galaxies, adopting companion animals, visiting parks and zoos to commune with other beasts. In the process, we discover our shared identity.

It's animal by animal that you save a species.

I swear I will not dishonor my soul with hatred, but offer myself humbly as a guardian of nature, as a healer of misery, as a messenger of wonder, as an architect of peace.

Happiness doesn't require laughter, only well-being and a sense that the world is breaking someone else's heart, not mine.

There are well-dressed foolish ideas just as there are well-dressed fools.

Because we can't escape our ancient hunger to live close to nature, we encircle the house with lawns and gardens, install picture windows, adopt pets and Boston ferns, and scent everything that touches our lives.

We have vexed and bothered every plant and every animal on every continent.
