The total negative impact of such a society on the environment can be expressed, in the simplest terms, by the relation, where P is the population, and F is a function which measures the per capita impact. The factors such as population growth, environmental degradations, poverty and effects of climate change are been explored. is a venture of the Millennium Alliance for Humanity and the Biosphere. Thus a fairer measure is combined consumption of aluminum and steel, which has risen only 117 percent since 1940. Factors affecting population growth The population growth is determined mainly by birth rate, death rate, and migration patterns (immigration and emigration). Everything comes back together to bite back on the hand that has no control over what it does. Consider, for example, the recent article by Coale (1), in which he disparages the role of U.S. population growth in environmental problems by noting that since 1940 “population has increased by 50 percent, but per capita use of electricity has been multiplied several times.” This argument contains both the fallacies to which we have just referred. Some of these are viral. 2. Another phenomenon capable of causing near-discontinuities is the synergism. Nor is there any reason to believe that modern medicine has made widespread plague impossible (21). These links involve energy and materials in their construction and use. Not only is there a connection between population size and per capita damage to the environment, but the cost of maintaining environmental quality at a given level escalates disproportionately as population size increases. Increase in population affects the economic, environmental and social development of the world. For instance, as cities push out into farmland, air pollution increasingly becomes a mixture of agricultural chemicals with power plant and automobile effluents. The ecological problems created by high-yield agriculture are awesome (3, 10) and are bound to have a negative feedback on food production. The need for food, space and raw materials has resulted in destruction of habitats and pollution. Technologies, income and resource levels are held at year 2000 values. In this context, a national policy of limiting population growth probably has a limited effect. This is a blog in the MAHB ‘Let’s Talk About Population’ Blog Series. A great deal of complexity is subsumed in this simple relation, however. Effects of Population Growth on our Environment! Moving people to more “habitable” areas, such as the central valley of California or, indeed, most suburbs, exacerbates another serious problem— the paving-over of prime farmland. Population growth causes a disproportionate negative impact on the environment. Among the most definite and devastating effects of overpopulation i… Questions should be directed to. The environment, culture, politics, food supply, and demand, the undermined ability of some of the natural resources to replenish - everything is affected by the growth of population. If we keep on doing that, it will slam down hard on biodiversity of Earth, as many species will disappear, because we left them without a home. Again, under the simplest assumption, population growth accounts for 45 percent of the increase. If there are more people, more fossil fuels will be burned into the atmosphere, which will then spiral back down on Earth, causing more pollution with the acid type of rains. While population growth, of any species, may be beneficial to a certain extent, there may come a time when the number in the population exceeds the natural resources available to sustain it. But population increased at the rate of 2.2%. But if the volume of sewage is such that its nutrient content creates a serious eutrophication problem (as is the case in the United States today), or if supply considerations dictate the reuse of sewage water for industry, agriculture, or groundwater recharge, advanced treatment is necessary. Indeed, the Food and Agriculture Organization of the United Nations has reported that in 1969 the world suffered its first absolute decline in fisheries yield since 1950. We must pay careful attention to sources of conflict both within the United States and between nations. These results underscore long-standing suspicions that population growth, translated through the inevitable uneven distribution into physical crowding, will tend to make the solution of all of our problems more difficult. Here the loss of free-flowing rivers and other economic, esthetic, and ecological costs of massive water-movement projects represent increased per capita diseconomies directly stimulated by population growth.
