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?
