The centre's 30 miles of woodland have become isolated as surrounding trees have been cut down to make way for farming. "It's as though the chimps are living on an island," explains Goodall. "They can no longer exchange genes with other groups and in the long term there will be the effects of in-breeding." In a bid to help save the dwindling natural environment, she has helped set up a programme for villagers from the shores of Lake Tanganyika to grow fruit and vegetables and plant trees. "We have now reached the stage where this can be replicated in other parts of Africa, so that the people themselves are helping to save the last forests," she says.
Sometimes the cruelty to chimpanzees is closer to home: Goodall was provoked by a recent US Airforce decision to hand over more than 100 creatures, which had been used for experimentation, to a toxicologist. They should go to a sanctuary, she argued, where they can live out their days in peace and quiet - something Goodall herself deserves. Apart from the occasional fortnight with her 94-year-old mother in England, or her grandchildren in Tanzania, her days are crammed with speaking and campaigning engagements. "I'm literally living in hotels. My spiritual home is Gombe - it's where I go to recharge my batteries. I had these wonderful, incredible years, living with the chimps, building the research station and getting knowledge. Now is the time for sharing". `Brutal Kinship' by Michael Nichols and Jane Goodall (Aperture, pounds 15.95) can be ordered from The Jane Goodall Institute UK, 15 Clarendon Park, Lymington, Hants SO41 8AX, 01590 671188; e-mail email@example.com
