Over Population.

Extracts from this document...


Lauren Hoff IB Biology 11 May 19, 2004 Jensen Over Population On October 12, 199, the 6th billionth Homo sapien was born on planet Earth. Every population on earth has a carrying capacity, the number of organisms an environment can support. Many scientists believe that we are dangerously flirting with this line. Although we are still growing exponential, the growth rate is beginning to slow, going from 4.9 in 1960 to a year 2000 calculation of 2.6. Since we our growth rate is slowing, we are considered to be in the transitional phase of a sigmoid curve, which is right before the plateau or carrying capacity. Over population in the world is affecting many things, such as water supply, food supply, and also the amount of land. ...read more.


The people were forced to live on over crowded farm land. Also, the amount of resources available was still the same as when it was with less people. Therefore, much of the rivers, such as the Yangtze River, dry up annually from over use. Many things are affect by the over use of water, such as grain production (agriculture), in which China is the second largest producer. Also, if China's agriculture is affected, it might not be able to feed the members of its own country, let alone export some of the cereal into developing countries. Measures are being taken in China, to reduce the over population problem, the main of which is restricting each family to have one child. ...read more.


In industrialized countries, many women are beginning to choose careers over large families, therefore reducing the number of children born in these areas. Creating this affect in developing countries will be difficult and almost impossible for several decades to come. Our natural resources are being diminished as our population increases, destroying not only our own habitat, but the habitat of millions of species on earth. Over population effects almost every aspect of life, from food to shelter to our natural ecosystems that we need to survive. Unless the exponential growth of human beings slows, and eventually begins going in reverse, the place we live will no longer be able to support us. Not much can really be done about slowly the population growth, besides attempting to slow reproduction (contraceptives), but attempts are being made by many parties. ...read more.
