The Problem of Population Growth and the Solution of...

The Problem of Population Growth and the Solution of Population Planning INTRODUCTION Human population growth, overpopulation, and earth’s biological carrying capacity have been concerns of scientists for many years. In 1679 Antoni van Leeuwenhoek estimated that the maximum number of people Earth can support is 13.4 billion and estimates have continued to vary drastically since then (Cohen, 1995). There are many ecological indicators, including desertification and water problems, which point to the likelihood that we are approaching our limit. There are many sub issues within this overall problem that must be addressed in order to work towards solving this problem, including sustainable living, water shortages, etc. However,†¦show more content†¦This was then multiplied by the area of the region and then all the regions were summed. Another method used by analysts was fitting mathematical curves to historical population sizes and extrapolating them into the future. A third method was to focus on a single assumed constraint on population, such as food, and how much of that constraint is needed for survival. However, this method does not take into account other constraints. A fourth method used was to reduce multiple requirements needed for survival to the amount of a single factor. For example, food, paper, timber, etc. were reduced to the area of land required to grow or produce them. A fifth method used involves the idea of population size being constrained by multiple independent factors, or the sum total of constraints. Liebig’s law of the minimum is used here, which states that the population size of a species is constrained by whatever resource is in shortest supply. The sixth method used involves the idea that population size is constrained by multiple interdependent factors and scientists have used system models to describe this. This method is probably the most accurate since it allows for changes in endogenous and exogenous variables. It takes into account that carrying capacity is always changing and is not stati c. Another idea that has been brought up, but not employed, is that nations should calculate their human carrying capacity separately. However, resources needed oftenShow MoreRelatedOverpopulation And The Problem Of Overpopulation1388 Words   |  6 Pagescondition wherein the total population of a particular region far exceeds the carrying capacity of the region. Although the term by and large refers to the ratio between population and the available area, the ratio between the population and available resources cannot be ignored. First, the rate at which the population is growing; the data compiled by the United Nations shows that the world population grew by 30 percent between 1990 and 2010. Second, the distribution of population; with China and IndiaRead MoreEssay on The Growing Population1374 Words   |  6 PagesA Growing Population: Problem or Excuse? The current worldwide population is around 6.9 billion and is expected to reach 9 billion by 2050 (Baird). This projected population number is down from the once predicted 16 billion (Baird) and while some are not concerned others are worried by any increase in population. Population growth is discussed in the articles â€Å"Too Many People?† by Vanessa Baird; â€Å"Population Control: How Can There Possibly Be Too Many of Us?† by Frank Furedi; and â€Å"The PopulationRead MoreOverpopulation Crisis1246 Words   |  5 Pagescould also be part of the solution. A few of these factors are discussed in an interview with Melanie Asriel, the Psychological Sciences Instructor at WKU of Glasgow, Kentucky. According to Melanie Asriel, â€Å"The lack of family planning and contraceptive use has contributed to this problem†¦contraception, education, and the including of available abortion†¦all kinds of education, such as, sex education, contraceptive educat ion†¦ would be my solution to an over-population problem† (M.

One of the major problems with increased population is higher waste production, which creates increased air, soil, and water pollution. To resolve this problem waste reduction must be of primary importance in preventing and reducing pollution. Waste management can be an expensive undertakingRead MoreThe Current World s Population1409 Words   |  6 Pagess population is approximately seven billion people, and the amount of time that it takes for the population to increase by another billion is decreasing with each billion. According to the World Population Data sheet, there will be about eight billion people by the year 2020, and this is due to its continuation of growth (Southwick 159). A clear understanding of the causes and what might possibly happen is the first step to dealing with the population crisis.

REL4 is a two-step solution program that will provide education and contraception, which will decrease the population growth.

Each day the air around us is becoming more polluted as the amount of carbon dioxide emitted into the atmosphere caused by human activities increases each day. As populati on continues to gradually increase, it is causing harmful effects in terms of air pollution. An increase in the number of people directly varies with the pollution that is emitted into the environment.

Overpopulation creates an abundant amount of issues ranging from environmental and social problems. Nations attaining copious amounts of population introduce a wide array of problems to the world around and such nations. These environmental problems consist of but are not limited to lack of resources such as food and water; which may cause malnutrition in large populations, poor air qualityRead MoreOverpopulation can be described as the failure of the world’s resources to sustain the population.1600 Words   |  7 Pagessustain the population.

The human population has reached a record 7,467,374,326 people as of 11/27/2016, and is growing at an exponential rate (Current World Population). With the Earth’s number of occupants multiplying so rapidly, our need for resources escalates alongside it. According to Edward O. Wilson, a sociobiologist at Harvard University, â€Å"the planet can hold 10 billion people at the uppermost population limit.†(How Many People Can Earth Support?) Once we reach that
