Since the beginning of modern civilization human population has been growing at a steady rate. The advancements that humans have made have increased life expectancy greatly. Now humans can live longer because of improved health, higher resistance and immunity to diseases and new medical techniques. There is an estimated 135 people in the world over 100 years of age and that number is expect to increase 16 times by 2050. Although this shows our achievements it also shows a negative side. We are straining our planet's resources, polluting our planet and also are now running out of space. We are becoming over populated. What used to be a small issue is now one of our greatest problems.

The trend continues to show it took 14 years to reach four billion, another 13 to reach five, and is expected to reach six billion, 12 years later, this year. This trend shows how...
