Human overpopulation refers to a situation where the number of people living within a specified geographical area exceeds its capacity regarding the available resources. When the population exceeds the resources then, there will be some problems that range from social, economic and health. Today, overpopulation is a global concern, given the adverse environmental implications of the phenomenon. Recent demographical studies done in 2009 found the world population to be 7.1 billion people and forecasted a possible growth of 2.4 billion by 2050. Countries such as China, India, and the USA are the global population leaders with a population of 1.34, 1.25 and 0.32 billion people respectively (Trevors 113).

Human overpopulation has a detrimental environmental impact. First, it leads to depletion of natural resources (Samways). The environmental ecosystem has a regular cycle whose capabilities are limited. Overpopulation exhausts the resources at a higher rate than the ecosystem can possibly replenish them and some resources cannot be replaced once they are exhausted. Depletion of vegetation cover, illegal logging, and wild hunting fires are other vices that are associated with human overpopulation. Further, human overpopulation is responsible for environmental degradation. Extensive dependence on oil, natural gas and use of coal industries results to high carbon dioxide gas (CO2). A collection of the CO2 gas in the stratosphere results in the formation of an ozone layer that has properties of retaining radiation heat from the earth, these consequently leads to global warming (Samways). Human overpopulation and industrialization go hand in hand, making it difficult to maintain a pollution free environment. Creating awareness by educating people as early as in their childhood along with adoption of birth control programs will help increase sensitivity in the societies on environmental …show more content…
When implemented effectively and on a large scale, the program has a potential to have a great impact on many citizens’ lives. The family planning programs will aid in reproductive health especially for women and young girls, and the overall wellbeing of the family unit. Most of the traditional concepts such as “early marriage and early births” and “more children greater happiness” will be discarded by most people. Recently, because of the program, people have adopted the concepts of late marriage and delay in childbearing age.
Additionally, family planning programs creates a favorable condition for economic development which has led to the improvement of living standards. The promotion of family planning program has enabled many countries, such as China, to lower its population growth and increase the GNP growth improving the country’s per capita level. Family planning plays a key function towards a sustained economic development which has further improved the living standards of the
