Ecology Population Growth Is a Term Paper

Chain migration refers to the migration of a population, whereas hierarchical migration refers to the migration of a certain segment of a population.

As can be gathered by these factors that influence population growth, community interactions plays a dominate force in population dynamics. The concept of community interactions can be used to encompass such factors as migration, wealth and trade. In other words, each community has specific needs and resources. Based on the available means, or lack of means, humans will interact with other communities in order to satisfy their needs, even if this need is nothing more than selling resources to another community.

Further, as our world continues to become more and more globalized, there continues to be an increasing interaction between the world's communities. Although much of these interactions are beneficial to humanity, in terms of the long-term effects they have on population growth, many can also be viewed as negative interactions. Take for example the many organizations and government programs that are established with the sole purpose of improving the health and lives of poorer nations. Although all of these programs are seen as being noble efforts of humanitarian aide, the end result is that it allows populations to live longer.This increase in life expectancy equates to an increase in population growth, which will lead to the numerous previously mentioned unhealthy effects as diminishing resources and increased pollution, to name only a few.

If one is to regulate this type of interaction, one would be in the tough position of arguing again humanitarian aid. For this reason, perhaps the better approach is to promote such programs as conservation and birth control as methods for regulating population growth. Otherwise, if the problem presented by population growth is simply ignored, the effects to our ecosystems, including our natural resources, will be detrimental. This is already being seen with the crisis of global warming, a phenomena at least partially caused by the earth's gradual overcrowding and the increased use of resources and pollution that come with this increase.
