The Population Explotion
In the last 80 years the earth's temperature has risen over half a degree. That may not sound much by if you consider that if the temperature rises 4 degrees, the global sea level will rise to 5m higher than it is today causing hundreds of coastal cities to be completely under water. This is caused partly by the amount of carbon dioxide in the atmosphere. The Greenhouse Effect. The Sahara desert is increasing its area by 150 hectares every year. This is caused by over logging and not regenerating the forests turning them into deserts. The ozone layer has been depleted 30% over Antarctica in the last 25 years, due to the build up of CFCs from air-conditioners and aerosols. Having considered some of the ways that humanity is destroying its inheritance; we can look more closely at the idea of 'overpopulation.' All too often, overpopulation is thought of as simply as crowding, too many people in a given area, too high a population density. If all the people from China and India lived in the continent of U.S. (excluding Alaska), it still would have a smaller population density than England, Holland or Belgium. Density is generally irrelevant to overpopulation. For instance, if you only took into considerati
on density, you would have to accept that Africa was 'under populated' because it has only 55 people per square mile, while Europe has 261 and Japan has 857. A more reasonable measure would take into account that over half of Africa's area is covered by desert or impenetrable forest, making its effective population density more like 117 people per square mile. That is still only about a fifth of that of the United Kingdom. Even by the year 2020, Africa's effective density is projected to grow only to that of France today and few people consider France excessively crowded or overpopulated. You may find this unfair or cruel but if you have too many children you are only being cruel to their children and their children's children. Do you want them to grow up in a world where there is not enough food or not enough power to generate their homes. Where it is crowed and hot with countries having wars for the rights to the small amount of resources left! Don't be selfish, think of your future generations, if we don't start now thinking of the future the future is doomed! Overpopulation is the cause of all the factors contributing to the destruction of the earth. If we make a start, if we can stop it in its tracks, we can start to clean up our act because at the moment our Earth is on a major downward spiral! If its current human occupants are degrading the long-term carrying capacity of an area, that area is overpopulated!
