Effects of Population Changes on the Environment
1. An introduction that describes the forces behind population change
Change in population takes into account the increase or decrease in the size of population in a particular period of time. In the contemporary, the population of the world has been progressively increasing. There are different forces that account for the change in population. One of the key forces is births. In delineation, the number of births causes an increase in population and having a high birth rate gives rise to a high increase in population. Another force to population change is deaths. In particular, the number of deaths have a direct effect on the decline of the population and therefore a high death rate gives rise to a high decline in population. Aspects such as growth and development in health care, technology, education have given rise to a positive population change. For instance poor healthcare causes a decline in population whereas advanced and developed medical care increases life expectancy and therefore an increase in population. In general, the rate of change in population of a particular area is obtained by subtracting the death rate from the birth rate. An additional key force to population change is migration. In delineation, migration encompasses the movement of individuals in and out of an expanse. Migration brings about population change in the sense that when people migrate from one region to another,...
Some of the key reasons for migration include employment, accessibility to services and amenities, natural disasters, and marriage (Stolley, 2005).
2. A discussion of the effects on the environment when population change results in urbanization
Population change through an incessant increase gives rise to urbanization. In delineation, urbanization takes into account the overall increase in population and signifies the movement of populaces from rural to urban expanses. This population has a massive impact on the environment. One of the effects takes into account pollution, which encompasses air, noise, and water pollution. Urbanization encompasses increased industries and also vehicles, which give rise to elevated contaminated and polluted air within the urban regions. Poor quality of water, inadequacy in availability of water, issues in disposal of waste, as well as high energy intake are aggravated by the increasing population demands. This indicates that population change leading to urbanization causes degradation of the environment (Uttara et al., 2012).
Urban populations interrelate with their environment. Urban populaces alter their environment by means of their depletion of food, energy, water, and land. Then as a result, the polluted urban environment impacts not only the health but also the quality of life of the urban populace.…
