“Here we are, the most clever species ever to have lived. So how is it we can destroy the only planet we have?”

And always I have this feeling-which may not be true at all-that I am being used as a messenger.

You may not believe in evolution, and that’s all right. How we humans came to be the way we are is far less important that how we should act now to get out of the mess we have made for ourselves.

Only when our clever brain and our human heart work together in harmony can we achieve our true potential.

A sense of calm came over me. More and more often I found myself thinking, This is where I belong. This is what I came into this world to do.

I like to envision the whole world as a jigsaw puzzle. If you look at the whole picture, it is overwhelming and terrifying, but if you work on your little part of the jigsaw and know that people all over the world are working on their little bits, that’s what will give you hope.

I think the best evenings are when we have messages, things that make us think, but we can also laugh and enjoy each other’s company.

Trees are living beings. And they have their own personalities. There are the young, eager saplings, all striving with each other. If you put your cheek against one of those, you almost sense the sap rising and the energy.

I like some animals more than some people, some people more than some animals.

Thousands of people who say they ‘love’ animals sit down once or twice a day to enjoy the flesh of creatures who have been utterly deprived of everything that could make their lives worth living and who endured the awful suffering and the terrors of the abattoirs

He had instigated a detailed study of the limb bones and locomotor patterns of a number of modern antelopes; the functions of varying bone structures of their legs could then be ascertained. Then, from the structure of fossil antelope bones reconstructed their movements.

Change happens by listening and then starting a dialogue with the people who are doing something you don’t believe is right.

The least I can do is speak out for those who cannot speak for themselves
