Does mother earth have the capacity to sustain continued population growth
That is the question I am going to answer in the following essay. We volition be smell at two persons who gave on that point opinion most the principal of existence process and their solutions. One called, Robert Malthus, the new(prenominal) person called Ester Boserup. They both differ a lot of each an some other(prenominal) in opinion. Boserup was more optimistic about it, although on the other get to Malthus was very sceptic and pessimistic. I exit include their arguments and their way of looking at population resurrectth later on, combined with my suffer view. some(prenominal) features are concurring about population growth. When the institution would collapse of its own infirmity, it pass on be collectable different factors. One of them will be due global warming. This is also one of the arguments of Malthus which influences his credo1.Population growth is a very important issue for geographers now a day. These geographers are for certain divided into 2 group s. One group focuses more on the Malthusian-way of persuasion and the other support Ester Boserups her ideas, which are more optimistic. Worries about population growth are not new. About 200 socio-economic classs ago, Malthus published a essay called The Principal of Population Growth. His main arguments in this essay were about the geometrically grow of population, while the resources available to support it tend to grow arithmetically. He presented his theory in response to optimists who thought that mankind groundwork master environment bottomless.They verified this idea with some new cures such(prenominal) as DDT which eliminates misquotes born with malaria, anti-biotics. During the same period, the Green Revolution greatly boosted solid food output through the cultivation of new disease-resistant rice and other food crops, and the use of fertilizers and more effective farming methods. These changes have contri moreovered to a dramatic increase in human population growth gr ade2. world-wide Warming is causing a big impact on population growth. The carbon dioxide is sacrificing the earths nature causing a enormous impact on water altitude. Increasing water altitude causes the sea direct to rise. This will finally result in floods of areas were bulk life. Due this fact, people will have to drift because otherwise they risk another deluge. Because of this process it will contribute to the fact that the earths living surface can decrease. As more people are settling on earth then people leaving it will result that there isnt enough space for such an amount of inhabitants.If you look at the facts of Population Growth, it will tell you that, every minute there are 5 babies born. This means that every year 87 million people are added to the world. In 1999 the World Watchers name said that population growth is slowing down due the fact of rising Death Rates. They estimated a 8,9 billion people on the world instead of the predicted 9,4 billion. Two-thirds o f this drop is because of falling birth rates, but one-third is due rising death rates. Three factors are pushing the death rates up, especially in sub-Saharan Africa and the Indian sub-continent3the HIV epidemicthe depletion of aquifers shrinking cropland area per person.We analyze the worlds carrying capacity with Net Primary Productivity. It represents the total food resource on earth. It has been calculated that we are using 40% of the telluric food supply. This leaves 60% left on earth, theoreticly human population would so be 2.5x the current level that is 2.55.9 = 15 billion, a number that will be reached within the next century if present trends continue4.Overall, the answer would be No to the question we asked earlier. Mother earth cannot sustain continuing population growth. Scientist keep making solutions to provide human better health care, but when you look at it, medicine cure people, which influences Mortality rate obviously. So on the other hand it speaks against i tself. Population growth is increasing pop off few years as it never did before and it is going to move on. As there are coming more inhabitants, there wont be enough space one day, to grow crops and shelters at the same time. globular warming is causing the world the heat up, increasing sea level and destroy rainforest (one of our big food resources on earth)
