food stays the same or even declines, human beings will face a scarcity of resources and overpopulation in the world. This is what happening right now. According to a well known biologist-Paul R. Ehrlich, who said ¡§The amount of food available restrains the size of any animal population, unless space, disease, predators, or some other factor sets lower limits¡(Ehrlich, 66). What he means is that food production is an element that control our population growth, this is because people cannot survive without food. When his idea is observed, it is evident that his idea is similar to Malthus¡s principle of population. Malthus stated, ¡§there is an imbalance between our ability to produce food and our ability to produce children.¡(Malthus 80) He said human beings are far better at making babies than are at finding food for survival. This problem, exists in all past and present societies, and must also exist in any future society as well. Therefore Malthus and Paul both agreed that the population could not increase without an increase of food. Without an excessive population, the world¡s fertile land can produce enough food, or even excess food. There will be a sufficient amount of natural resources reserve of human beings. Therefore the faster the population increases; the more resources will be used. When population keeps increasing, earth environment will be put into greater danger, the overexploitation of natural resources will continue and poverty will rise in most of the world countries. It is because more people consume more food and more resources to keep their needs. As a result, if there is not enough food, human population will decline.
             Malthus stated, ¡§the power of population to grow was 'indefinitely greater¡ than the power of the earth to produce subsistence.¡ (Malthus, 70) He also said that there was a difference between population growth and food supply. (msumusik.mursuky.edu/~felwell/http/malthus/i...
