Essay title: Math in Life
In the last few centuries, the number of people living on Earth has increased many times over. By the year 2000, there will be 10 times more people on Earth than there were 300 years ago.

How can population grow so fast? Think of a family tree. At the top are 2 parents, and beneath them the children they had. Listed beneath those children are the children they had, and so on and so on, down through each generation. As long as the family members continue to reproduce, the family tree continues to increase in size, getting larger with each passing generation. This same basic idea applies to the worlds population.

Exponential growth
Population grows in the same way that money grows when its left to compound interest in a bank. With money, growth comes through accumulating interest upon interest. The interest payments you accumulate eventually earn interest, increasing your money. With population growth, new members of the population eventually produce other new members of the population. The population increases exponentially as time passes.

WORLD POPULATION
Population
600,000,000
900,000,000
1,500,000,000
6,000,000,000
A crucial difference between money and population is that money can increase without limits while population cant. Any population of living creatures is constrained by the availability of food, water, land, or other important resources. Once those resources are depleted, a population wont continue to grow exponentially. It will plateau, or even decline, as a result of disease or malnutrition. Unlike calculating interest, calculating population growth is an imprecise business.
