At present, it seems the world may run out of energy, ciean water, food and land. Some of the poorest countries will soon have nuclear weapons, and will probably use them, as resources become scarce and wars begin to break out. If disaster is to be avoided, we must take action now to reduce the size of the world's population. The main reason that poor people have a lot of children is that children represent money: they can get jobs or provide their parents with free labour. So, the answer to the population problem lies in development. If their prosperity can be increased, people will begin to have fewer children. This has already happened in most of Europe, and is happening at the moment in countries such as South Korea and Taiwan. If the rich nations want this to happen, they must cancel the huge debts that are crippling many developing countries.
