Overpopulation and lack of respect for nature can result in the extinction of an increasing number of animals and plants. Every 20 minutes one species of animal or plant becomes extinct and about every 20 minutes the world population increases by 3,000.
In the course of 20 years about 80% of Borneo's rainforests have been cleared and replaced by the more profitable palm oil trees. Palm oil is used in food, cosmetics and also as biofuel in cars.
The rainforests have been and still are the habitat of Borneo's orangutan, which is now in danger of extinction.
Animals are our fellow creatures on Earth, and without wildlife the Earth would be much poorer. The American Chief Seattle (1786-1866) once said: 'If there were no wild animals, man would die of spiritual loneliness, and what happens to wild animals will also happen to man.'
David Attenborough: 'I've seen wildlife under mounting human pressure all over the world and it's not just from human economy or technology - behind every threat is the frightening explosion in human numbers.'
Borneo's orangutan is an endangered species: 'Will you miss me when I'm gone?'
