The great ecosystems are like complex tapestries - a million complicated threads, interwoven, make up the whole picture. Nature can cope with small rents in the fabric; it can even, after a time, cope with major disasters like floods, fires, and earthquakes. What nature cannot cope with is the steady undermining of its fabric by the activities of man.

All over the world the wildlife that I write about is in grave danger. It is being exterminated by what we call the progress of civilization.

I do wish you wouldn't argue with me when I'm knitting.

Zoos should concentrate more on the preservation side of things.

Until we consider animal life to be worthy of the consideration and reverence we bestow upon old books and pictures and historic monuments, there will always be the animal refugee living a precarious life on the edge of extermination, dependent for existence on the charity of a few human beings.

You cannot begin to preserve any species of animal unless you preserve the habitat in which it dwells. Disturb or destroy that habitat and you will exterminate the species as surely as if you had shot it. So conservation means that we have to preserve forest and grassland, river and lake, even the sea itself. This is vital not only for the preservation of animal life generally, but for the future existence of man himself - a point that seems to escape many people.

As I watched the pulsing fire among the trees and heard the beat of the drum merge and tremble with the voices, forming an intricate pattern of sound, I knew that someday I would have to return or be haunted forever by the beauty and mystery that is Africa.
