Geography: Physical Essay Question Describe and explain the ways in which a rapid growth in population can pose a threat to the physical environment. Rapid growth in population is a large in crease of the amount of people living in a region over a short period of time, which can lead to various consequences. There are many examples of rapid population increase around the globe this essay: India and China. Environmentalists have long been concerned about the resources threatened by rapidly growing human populations, focusing on issues such as deforestation, desertification, air pollution and global warming. But the worst-case scenario for people experiencing overpopulation is a lack of fresh, clean water. Rapid population growth can lead to many social problems but this essay will look at various hazards a rapid growth in population puts on the physical environment. When the population of a region increases rapidly over a short period drastic consequences can occur.

China's over population and growth has made the environment extremely hazardous to the health and well being of Asia's culture. A country with 1,311,709,000 people, it has put a strain on their environment and has made it a global issue with China's pollution affecting countries like the USA and Scandinavia.

Conclusion

China, which now imports many tons of food, illustrates this problem. Certainly improved technology will assist in more effective management and use of resources, but it cannot produce an unlimited flow of those vital natural resources that are the raw materials for sustained agricultural production. For instance, fertilizers enhance the fertility of eroded soils, but humans cannot make topsoil. Indeed, fertilizers made from finite fossil fuels are presently being used to compensate for eroded topsoil. Also the supplies of fresh water that are available not only for agriculture but also for industry and public use. All China's rivers are consider to be polluted at some level. Strategies for the future must be based first and foremost on the conservation and careful management of land, water, energy, and biological resources needed for food production. Our protection of world resources must be changed and the basic needs of people must be balanced with those resources that sustain human life. The conservation of these resources will require coordinated efforts and incentives from individuals and countries. Once these finite resources are exhausted they cannot be replaced by human technology. Further, more efficient and environmentally sound agricultural technologies must be developed and put into practice to support the continued productivity of agriculture. ...read more.
