You will find many statements that seem to clearly explain issues related to World Population. Test these against each other and seek as much hard evidence as you can before attempting to make your own decisions. A few typical statements are listed here to give you a start. Some of these are contradictory, simplistic or simply wrong. They usually represent a particular view of the world and the vested interests of the people making them.
The world already has too many people?
New technology will always find a way to provide food and resources for the world population, no matter how big.
The massive world population will destroy the environment and eventually all people.
If the poor worked harder they could feed themselves.
The World Bank has forced poor regions into debt and now requires them to grow commodities like coffee instead of food.
Family size should be regulated (e.g. China's one child policy).
China's one child policy has created as many problems as it has solved.
Distribution of the world's population is the problem; migration is the answer.
Migration is not the answer; as Indonesia is discovering.
