It is also said that the population will double again by the year 2054 to about 12 billion people. If this continues than we are going to exceed our growth capacity on earth and the ability to provide for all our basic needs for survival. With the corruption of our environment the capacity that the earth holds actually decreases over time leaving the environment with the inability to be able to support the people living. The survival of the population correlates with the survival of the environment. There are many things that can impact the ecosystem that carries and provide life for so many people. In order for humans and other organisms to survive we have to consume large amounts of food and we do this by modifying land to produce food.
