The whole of science, and one is tempted to think the whole of the life of any thinking man, is trying to come to terms with the relationship between yourself and the natural world. Why are you here, and how do you fit in, and what's it all about.

I believe that conservation education is all about being excited about something. Seeing passion and enthusiasm helps push an educational message.

People must feel that the natural world is important and valuable and beautiful and wonderful and an amazement and a pleasure. The question is, are we happy to suppose that our grandchildren may never be able to see a monkey except in a picture book?

People are not going to care about animal conservation unless they think that animals are worthwhile.

At Monkeyland in Plettenberg Bay you've got the lemurs and monkeys leaping through the trees overhead. It's a chance to remember what the world can really be like.

The most important environmental issue is one that is rarely mentioned, and that is the lack of a conservation ethic in our culture.

Environmentalism opposes reckless innovation and makes conservation the central order of business.

I believe our biggest issue is the same biggest issue that the whole world is facing, and that's habitat destruction.

Most people I’ve met who weren’t kind to animals weren’t kind to people either. Kindness is Kindness. Simple as that.

Let us not take this plant for granted.

Never, never be afraid to do what’s right, especially if the well-being of a person or animal is at stake.

Our task must be to free ourselves by widening our circle of compassion to embrace all living creatures.

Since I’ve been spending my time in nature with animals I found out that, we are the wild savages and they are the ones who are actually civilized.

If you don’t like seeing pictures of violence towards animals being posted, you need to help stop the violence, not the pictures

Of all the animals, man is the only one that is cruel. He is the only one that inflicts pain for the pleasure of doing it.

The greatness of a nation can be judged by the way its animals are treated.

I have developed a deep respect for animals. I consider them fellow living creatures with certain rights that should not be violated any more than those of humans.

When a man has pity on all living creatures then only is he noble.

Animals can communicate quite well. And they do. And generally speaking, they are ignored.

The worst sin toward our fellow creatures is not to hate them, but to be indifferent to them: that's the essence of inhumanity.
