In a Horizon special, naturalist Sir David Attenborough investigates whether the world is heading for a population crisis. In his lengthy career, Sir David has watched the human population more than double from 2.5 billion in 1950 to nearly seven billion. He reflects on the profound effects of this rapid growth, both on humans and the environment. While much of the projected growth in human population is likely to come from the developing world, it is the lifestyle enjoyed by many in the West that has the most impact on the planet. Some experts claim that in the UK consumers use as much as two and a half times their fair share of Earth’s resources. Sir David examines whether it is the duty of individuals to commit not only to smaller families, but to change the way they live for the sake of humanity and planet Earth.
This BBC documentary is about us – the human beings living on the planet earth. Naturalist Sir David Attenborough investigates if an ongoing rise in population growth is possible or if we have to introduce birth control to prevent overpopulation. The size of the human population is currently nearly 7 billion people, which is much more than the 2.5 billion in 1950. Until 2050 the UN is expecting about 9 Billion people to be living on this world. One of the big reasons is, that people are becoming older and older, not necessary an increase in family size. The rise of China is one of the big roles, but also the population of other countries will increase. But can we provide enough foot and shelter for all those people without damaging our nature for ever?How Many People Can Live on Planet Earth?,
