Only if we understand, will we care. Only if we care, will we help. Only if we help, shall all be saved.
My family has very strong women. My mother never laughed at my dream of Africa, even though everyone else did because we didn't have any money, because Africa was the 'dark continent', and because I was a girl.
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.
Change happens by listening and then starting a dialogue with the people who are doing something you don't believe is right.
I don't have any idea of who or what God is. But I do believe in some great spiritual power. I feel it particularly when I'm out in nature. It's just something that's bigger and stronger than what I am or what anybody is. I feel it. And it's enough for me.
I never wanted to be a scientist per se. I wanted to be a naturalist.
I don't spend that much time being introspective, believe it or not. All I know is that I grew up not questioning God because that's how you are. God was there like the birds and the wind.
I was brought up to understand Darwin's theory of evolution. I spent hours and hours in the Natural History Museum in London looking at the descriptions of how different kinds of animals had evolved, looking at the sequence of fossil bones looking gradually more and more and more and more like the modern fossil.
I'm highly political. I spend an awful lot of time in the U.S. trying to influence decision-makers. But I don't feel in tune with British politics.
And I thought how sad it was that, for all our sophisticated intellect, for all our noble aspirations, our aggressive behavior was not just similar in many ways to that of the chimpanzees – it was even worse. Worse because human beings have the potential to rise above their baser instincts, whereas chimpanzees probably do not.
Chimpanzees, gorillas, orangutans have been living for hundreds of thousands of years in their forest, living fantastic lives, never overpopulating, never destroying the forest. I would say that they have been in a way more successful than us as far as being in harmony with the environment.
Cruelty is a terrible thing. I believe it is the worst human sin.
Certainly, if you look at human behavior around the world, you have to admit that we can be very aggressive.
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.
But let us not forget that human love and compassion are equally deeply rooted in our primate heritage, and in this sphere too our sensibilities are of a higher order of magnitude than those of chimpanzees.
So, let us move forward with faith in ourselves, in our intelligence, in our indomitable spirit. Let us develop respect for all living things. Let us try to replace violence and intolerance with understanding and compassion and love.
My mother always used to say, 'Well, if you had been born a little girl growing up in Egypt, you would go to church or go to worship Allah, but surely if those people are worshipping a God, it must be the same God' - that's what she always said. The same God with different names.
In 1975, when my students were kidnapped by rebels, I was accused of hiding instead of trying to save them, and of not giving enough money for their ransom. I wasn't believed.
I think we're still in a muddle with our language, because once you get words and a spoken language it gets harder to communicate.
Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.
Attacks by other chimpanzees are the second most frequent cause of death at Gombe, after disease. Through.
We can't leave people in abject poverty, so we need to raise the standard of living for 80% of the world's people, while bringing it down considerably for the 20% who are destroying our natural resources.
Sometimes I [longed to be a chimp]... I just wanted to know... what it felt like in the evening to be making a nest and what it felt like to be a female when a big male comes thundering in.
From my perspective, I absolutely believe in a greater spiritual power, far greater than I am, from which I have derived strength in moments of sadness or fear. That's what I believe, and it was very, very strong in the forest.
Arguably, we are the most intellectual creatures that's ever walked on planet Earth. So how come, then, that this so intellectual creature is destroying its only home?
I thought my life was mapped out. Research, living in the forest, teaching and writing. But in '86 I went to a conference and realised the chimpanzees were disappearing. I had worldwide recognition and a gift of communication. I had to use them.
As a small child in England, I had this dream of going to Africa. We didn't have any money and I was a girl, so everyone except my mother laughed at it. When I left school, there was no money for me to go to university, so I went to secretarial college and got a job.
Only when our clever brain and our human heart work together in harmony can we achieve our true potential.
What you do makes a difference, and you have to decide what kind of difference you want to make.
Words can be said in bitterness and anger, and often there seems to be an element of truth in the nastiness. And words don't go away, they just echo around.
We have language and they do not. Chimps communicate by embracing, patting, looking - all these things. And they have lots of sounds. But they cannot sit and discuss. They cannot teach about things that are not present, as far as we know.
I don't think that faith, whatever you're being faithful about, really can be scientifically explained. And I don't want to explain this whole life business through truth, science. There's so much mystery. There's so much awe.
Very few Westerners, I thought, could tolerate such a way of life- for it would mean having to forgo the luxuries which we had come to think of as necessities.
The least I can do is speak out for those who cannot speak for themselves.
That is our hope. Because if we all start listening and helping, then surely, together, we can make the world a better place for all living things. Can't we?
Some people say... that violence and war are inevitable. I say rubbish: Our brains are fully capable of controlling instinctive behavior. We're not very good at it though, are we?
The least I can do is speak out for the hundreds of chimpanzees who, right now, sit hunched, miserable and without hope, staring out with dead eyes from their metal prisons. They cannot speak for themselves.
Chimps can do all sorts of things we thought that only we could do - like tool-making and abstraction and generalisation. They can learn a language - sign language - and they can use the signs. But when you think of our intellects, even the brightest chimp looks like a very small child.
Whatever we believe about how we got to be the extraordinary creatures we are today is far less important than bringing our intellect to bear on how do we get together now around the world and get out of the mess that we've made. That's the key thing now. Never mind how we got to be who we are.
I had been told from school onwards that the best definition of a human being was man the tool-maker - yet I had just watched a chimp tool-maker in action. I remember that day as vividly as if it was yesterday.
I think the most important thing is to keep active and to hope that your mind stays active.
When I look back over my life it's almost as if there was a plan laid out for me - from the little girl who was so passionate about animals who longed to go to Africa and whose family couldn't afford to put her through college. Everyone laughed at my dreams. I was supposed to be a secretary in Bournemouth.
When I was two, a dragonfly flew near me. A man knocked it to the ground and trod on it. I remember crying because I'd caused the dragonfly to be killed.
It was both fascinating and appalling to learn that chimpanzees were capable of hostile and territorial behavior that was not unlike certain forms of primitive human warfare.
If we do not do something to help these creatures, we make a mockery of the whole concept of justice.
Here we are, the most clever species ever to have lived. So how is it we can destroy the only planet we have?
I love dogs, not chimps. Some chimps are nice, and some are horrid. I don't actually think of them as animals any more than I think of us as animals, although both of us are.
I was born in London in England in 1934. I went through, as a child, the horrors of World War II, through a time when food was rationed and we learned to be very careful, and we never had more to eat than what we needed to eat. There was no waste. Everything was used.
