Exponential Population Growth
Introduction
According to the International Program Center, U.S. Census Bureau, the total population of the World, projected to 03/27/08 at 19:37 GMT (EST+5) is 6,657,527,872. (US Census Bureau) This rapid growth in population means little to most people living in this today’s world but it’s a phenomenon that should be a concern to all. It took from the start of human history to the industrial revolution around 1945 for the population to grow to 2 billion. If we then look at the figures after 1945 then we would realize that this figure has more than doubled and even tripled. There is a fear that if left uncontrolled and this figure continues to grow exponentially the world population could reach a total of 8 – 12 billion by the end of the 21st century. The world's current growth rate is about 1.14% which would cause the population to double in 65 years. The world's growth rate peaked in the 1960s at 2% which was projected to double after 35 years.
