Do  you know how fast our world population is growing? In October 1999, our world population will reach 6 billion. If you see this in the context of human history, you will realise how rapid is the  growth rate. It was  only in the early 1800s that the world population reached its first billion, and it reached its three billion in the 1960s. However, it took just 12 years for the population to grow from five billion in 1987 to reach 6 billion in 1999 ! Do we control growth, or does growth control us?
