It will Overpopulation OVER POPULATION It will be very comfortable for one person to stay in a single bed but it will be less and less if there is another person stay in that bed. It could be similar to the earth nowadays. What will happened if there are 10 people in a single bed? Everybody can think about the result of too many people in a small place.

The world population is increasing day by day but the side of the earth stills the same. There will be too many people on earth and people will be run out of resources, water, space and food. How and where can the next generation live and survive? The consequences of over population cause many effects on the environment, which might cause extinction of many species and the most important is human species. In 1996, the World Conservation Union (IUCN), completed the first-ever extensive survey of the status of animal life on Earth. The 600 plus participating scientists concluded that of the species surveyed, 34 percent of fish, 25 percent of mammals and amphibians, 20 percent of reptiles, and 11 percent of birds are threatened with extinction.

Another 5 to 14 percent of species in these groups are nearing threatened status. The leading cause of vertebrate declines is human destruction of old growth forests, wetlands, chaparral, and other rich habitats, Worldwatch reports. Worldwide, over two-thirds of the earths habitable land surface has been significantly disturbed by human activities. Nearly half of the worlds 233 primate species are threatened, largely because of their dependence on large expanses of tropical forest, a habitat under siege around the globe. In hotspots of forest loss, such as Madagascar, the Atlantic rainforest of eastern Brazil, and Southeast Asia, roughly 70 percent of primate species face extinction. from Losing Strands in the Web of Life: Vertebrate Declines and the Conservation of Biological Diversity by John Tux hill, Worldwatch Institute.

And one day on the earth there will be no animals, no trees and the ocean is fulfilled with waste and dust. People cause all of those things by the over of population by the over use of resources instead of adding more value to them, make them become richer, and people or the next generation can use them in 100 years. The over population makes it harder to control or to organise all sorts of things. According to a study of 50 countries by Paul Harrison (The Third Revolution, Taurus, 1992) those areas with the greatest population density retain the least wildlife habitat.

For example, countries with population densities under 294 people per square kilometer (such as the US) retained an average of 59 percent of wildlife habitat. Nations with densities under 379 per square kilometer retained 45 percent on average, while nations with densities of up to 454 per square kilometer retained only one third of their original habitat. In the most crowded countries averaging from 1190 to 1888 people per square kilometer barely 15 percent of original habitat remained. In the future there will be more and more people in a small place and the original habitat will endanger. Moreover, human activities negatively affect the Earth s atmosphere through releases of pollution that causes smog, acid rain, and depletion of the ozone layer.

This is directly related to human numbers and lifestyles, because it is largely a result of emissions from automobiles and industrial plants. World vehicle production is now approaching 40 million units annually, and the total world fleet is half a billion vehicles. As more people operate more automobiles and demand more energy produced by burning oil, coal and natural gas, emissions and therefore air pollution will increase further. Increasing levels of carbon emissions are also linked to what may be the most serious long-term threat to humanity global warming and climate change. Because of the pollution, it affects people s health such as the blood of children in the urban area has lead content levels much higher than children s in rural area.

And people who live in urban area have higher chance of having high blood pressure or higher death rate causing by cancer or other diseases than people in rural area have. What have people done in order to solve this problem? What an individual can do for this problem? Normally an individual thinks that this kind of problem is too big for themselves but they were wrong because if individuals coming together they would make a difference. If there is only one individual want to change or to improve something this will be impossible. People must do it together, they have to share their own ideas, and working together is the best solution for this.

However, before working together about his problem each individual have to understand well about this problem and they themselves must have a strong attitude about it. This is like the ants getting food home and it is almost impossible for an individual ant to carry a big fly home but it become much easier if the all the ants work together to carry that big fly home. In China they have the one child policy, because the population in China is too big at this moment. It increasing day by day and if they do not have a suitable solution for this problem it can be a disaster.

However, there are a lot of problems for this solution in China because people in Asia still keep their attitude about having boy or girl. Furthermore for some people they go oversea and have more than one child they will not dare to go back their country and they have to stay in the other country as a refugee. The government should let every body know about the consequences of overpopulation and therefore people will follow the plan by themselves but not by forced. The government also can reduce the increase of population by let people be educated as much as possible because they can read and understand information which is good for reducing the population. 324
