Introduction Overpopulation can be defined as an undesirable condition where the existing population of human beings exceeds what the world can be able to sustain Howard 2. World overpopulation is attributed to a number of factors and effects that have been discussed below.
Decreased Death Rate The difference between the overall death rate and birthrate has affected the world population growth. If the death rate would be equal to the number of children born in a year then there would be stability in the population Howard 2.
One factor that first caused the imbalance between the two is the discovery of agriculture which provided our ancestors with enough nutrition without going for hunting.
This factor thus contributed to overpopulation due to enough nutritious food. Improved Medical Facilities The industrial revolution led to advancement in technologies that enabled better means of food production thus allowing more people to access enough food. Moreover, there were increased medical discoveries by scientists which enabled people to overcome a number of diseases hence a decline in death rate.
Chronic illnesses that claimed a big number of lives now could be cured using the invented medical vaccines Howard 2. Therefore, a combination of the rich supply of food and the decreased mortality rate marked the beginning of world overpopulation.
More hands to fight poverty This refers to the psychological component of overpopulation. Thousands of years ago, the infant mortality rate was very high due to poverty and poor medical care. This forced families to give birth to many children to make up for the huge number of deaths.
Consequently, the immigrants end up settling there which leads to overcrowding. The difference between the numbers of people that enters the country and those that leave becomes small and this affects the population density thus becoming the root of overpopulation.
Effects of World overpopulation: Natural Resources Depletion The fast growing population leads to depletion of natural resourses.
This is due to the stiff competition for the limited natural resources such as land, food and water. The aggressive competition for the limited resources has led to much depletion of natural resources. Environmental Degradation The increased use of oil, coal and natural gas has had adverse effects to the environment.
More industries and factories have been started to sustain the growing population.
This in turn affects the environment due to emission of harmful gases which cause global warming Thomlinso n Moreover, people have cleared more land for settlement and this in turn has affected world climatic conditions.
Increased Unemployment Rate Overpopulation in the world results in general unemployment as there are no enough jobs to sustain the growing population. It further leads to the rise in criminal acts since people resort to stealing and violence to fend for themselves and their families.
High Living Costs World overpopulation causes a high difference between supply and demand. This causes prices of goods and commodities to rise which include shelter, food and healthcare services and facilities Thomlinson This consequently means that people will be required to incur more expenses in order to survive and be able to feed their families.
Conclusion In summary, the world overpopulation is attributed to a number of factors which include decreased death rate, improved medical services, immigration among many others. On the other hand the overpopulation leads to adverse effects that negatively affect human life and their environment.
