For example, because the demand for uncontrolled colonies of water due to the Southern California Los Angeles US is very high that they have from the outside 350 km, so as of 2012, over 14.9 million (Allianz , 2014) population (see Appendix I) Import (WordPress, 2012). But also need to make sharing of urban and rural areas of water and other small neighborhood by doing this as well as making this costly. As in Los Angeles, as another example in Japan, Tokyo is a large-scale city of control.
It is thought that the resources of the earth will be restricted, but although it is done, the possibility of population growth is not so. The residential land area and the resources available to the earth are limited. As the population increases, the need for additional water and other natural resources is also rising. Fragile soil is dry, the inhabitants must move again to find the land to maintain the land. Through this process, wild animals and plant species will disappear. As the population grows and the need for additional housing for agricultural land use, growing, deforestation will be deployed. Every year, 40 million acres of tropical forests are planted and cut down for cultivation and fuel. It is estimated that over 80% of the world's original forests are being destroyed. In Haiti, due to the need to increase the use of storage space and logging of trees, caused large-scale deforestation, domestic heating and cooking charcoal.
As the world's population continues to grow, the number of agricultural lands required to provide adequate food is also increasing. According to the Food and Agriculture Organization (FAO), the majority of the land was covered with forests, stating that more than 40% of the earth 's surface is composed of current agricultural land. For example, most of Europe was covered by dense temperate forest once, but over time it was driven by population growth, deforestation linked to more agricultural land. According to the concerned scientific alliance, he said that 3 billion tons of carbon dioxide is present in the atmosphere each year from deforestation. The damage occurs every year up to 13 million hectares, most of which occurred in the Amazon rainforest. Here, the evaporation and condensation cycle area, the possibility of the forest became savanna and the remaining increase was interrupted
As the population increases, deforestation has increased. Pressure development and urbanization, we will not be able to enjoy rich green results. In the process of deforestation, the forest on the earth is a massive clean-up and destruction, which impairs the quality of our rich land. Forest destruction has a negative impact on our environment. Because it happens to be without that house in the forest, wild animals living in the forest, many of them are decreasing and extinct, they can not survive. In the course of deforestation, some animals lose their habitat. To deforestation, we have lost a few lost trees and plants
