The theorizing about population population size and change have remained an important subject since time immemorial.
Changes in atmospheric composition and consequent global warming. Rich countries with high population densities have low rates of infant mortality. It results in human threats including the evolution Overpopulation infant mortality and life expectancy essay spread of antibiotic resistant bacteria diseases, excessive air and water pollution, and new viruses that infect humans.
Increased chance of the emergence of new epidemics and pandemics. However, rich countries with high population densities do not have famine. Poverty and inflation are aggravated by bad government and bad economic policies. Many countries with high population densities have eliminated absolute poverty and keep their inflation rates very low.
However, this problem can be reduced with the adoption of sewers. For example, after Karachi, Pakistan installed sewers, its infant mortality rate fell substantially. Laws regulate and shape politics, economics, history and society and serve as a mediator of relations and interactions between people.
It was even speculated by Aldous Huxley in that democracy is threatened due to overpopulation, and could give rise to totalitarian style governments. David Attenborough described the level of human population on the planet as a multiplier of all other environmental problems.
According to Paul R. We want to build highways across the Serengeti to get more rare earth minerals for our cellphones. We grab all the fish from the sea, wreck the coral reefs and put carbon dioxide into the atmosphere.
We have triggered a major extinction event A world population of around a billion would have an overall pro-life effect.
This could be supported for many millennia and sustain many more human lives in the long term compared with our current uncontrolled growth and prospect of sudden collapse If everyone consumed resources at the US level — which is what the world aspires to — you will need another four or five Earths.
Williams  argue that third world poverty and famine are caused in part by bad government and bad economic policies.
Resources[ edit ] Youth unemployment is also soaring, with the economy unable to absorb the spiraling numbers of those seeking to enter the work force. Many young people do not have the skills to match the needs of the Egyptian market, and the economy is small, weak and insufficiently industrialized Instead of being something productive, the population growth is a barrel of explosives.
It also depends on how resources are managed and distributed throughout the population. The resources to be considered when evaluating whether an ecological niche is overpopulated include clean waterclean air, food, shelter, warmth, and other resources necessary to sustain life.
If the quality of human life is addressed, there may be additional resources considered, such as medical care, education, proper sewage treatmentwaste disposal and energy supplies.
Overpopulation places competitive stress on the basic life sustaining resources,  leading to a diminished quality of life.
With the global population at about 7. Weather patterns, elevation, and climate all contribute to uneven distribution of fresh drinking water.
Without clean water, good health is not a viable option. Besides drinking, water is used to create sanitary living conditions and is the basis of creating a healthy environment fit to hold human life.
In addition to drinking water, water is also used for bathing, washing clothes and dishes, flushing toilets, a variety of cleaning methods, recreation, watering lawns, and farm irrigation. Irrigation poses one of the largest problems, because without sufficient water to irrigate crops, the crops die and then there is the problem of food rations and starvation.
In addition to water needed for crops and food, there is limited land area dedicated to food production, and not much more that is suitable to be added.
Arable land, needed to sustain the growing population, is also a factor because land being under or over cultivated easily upsets the delicate balance of nutrition supply. There are also problems with location of arable land with regard to proximity to countries and relative population Bashford Access to nutrition is an important limiting factor in population sustainability and growth.
No increase in arable land added to the still increasing human population will eventually pose a serious conflict. Although plants produce 54 billion metric tons of carbohydrates per year, when the population is expected to grow to 9 billion bythe plants may not be able to keep up Biello.
Food supply is a primary example of how a resource reacts when its carrying capacity is exceeded.
By trying to grow more and more crops off of the same amount of land, the soil becomes exhausted. Because the soil is exhausted, it is then unable to produce the same amount of food as before, and is overall less productive.
Therefore, by using resources beyond a sustainable level, the resource become nullified and ineffective, which further increases the disparity between the demand for a resource and the availability of a resource. There must be a shift to provide adequate recovery time to each one of the supplies in demand to support contemporary human lifestyles.Having one fewer child is the most effective way an individual would have to fight climate change.
The next best actions are selling your car, avoiding long flights, and eating a vegetarian diet, according to a study published in Environmental Research Letters. Identification. Christopher Columbus landed in Puerto Rico in , during his second voyage, naming it San Juan Bautista.

However, as new data has. Population Explosion And Social Problems Economics Essay. Print Reference this. Published: 23rd March, a fast increase in the size of a population caused by such factors as a unexpected decline in infant mortality or an increase in life expectancy.
