21. What is the expected world population in 2020?

Most countries are trying to reduce their growth rate. Zero population growth means that as many people are being born as there are dying. To achieve zero population growth, each couple would need to have no more than two children (to replace the parents). Even if this number is achieved, the population will continue to grow because the parents will still live on for decades, as their children have children, and their children have children...... The rate of growth in developed nations has become more constant in recent years, while many developing nations are still growing exponentially.
