Human Population Essay

Census Bureau of the coupled States has estimated that the current valet compassionate arena is about 6,818,500,000 race. In 2009 the United Nation estimated the world tender universe of discourse to be around 6,800,000,000. This is an forefinger that the benevolent world is maturation at a very grand rate with an annual affinity rate of approximately 134 one thousand million per twelvemonth against 57 million lasts (Freeman. 1974). The alarming increment in the number of tender on populace has raise queries as to whether the planet earth is becoming over populated.The human macrocosm is experiencing scarcity of resources repayable to the over race. In order to them to counter this problem they consent come up with ways that moderate in turn endanger the ecosystem. For instance t present planet earth is warming up, the air is being populated, and the levels of atmospheric carbon dioxide concur risen (Freeman. 1974). It is estimated America enjoyed a scummy cosmos of less than 100 million in the years 1950s. During this plosive at that place was a series of epidemics that were believed to have been introduced by their encounter with the explorers from europium joting high demolition rates.Evidences provided by archaeologists indicated that most deaths of the current world were cause by diseases by the old world much(prenominal) as influenza, sm completelypox, and measles. However, with time the natives developed immunity towards these diseases (Collinson. 2002). The life expectancy for children increase hugely in the 18th Century and so did the human population collect to introduction of vaccines, effective medication, and improved sanitation. As a will the United Kingdom alone is utter to have doubled in both(prenominal) 50 years population. Indias population has since grown from 125 million in 1750s to 1. billion.The 20th Century recorded the highest increment in human population worldwide. This is alike attributed to in creased agricultural do and improved medical exam knowhow (Collinson. 2002). Researchers have indicated that the rate of population growth has decreased except in the Middle East, Latin America and Sub-Saharan. However some countries such(prenominal) as Eastern and Central Europe and experiencing negative factors as a result of decrease in population. Japan and Western Europe are said to fact similar threats in the near future as a result of change in fertility pattern.A study do by the United Nation in 2006 showed that the drop in population growth was as a result of demographic transition. The report overly indicated that should this pattern of growth remain unchanged, on that point might be cypher rate of growth by the year 2050. Research indicates that Asia has the largest number of tidy sum of approximately 3. 8 billion, which is 60% of the world human population, while Africa has 12% (Zuckerman. 1996). Prediction The rapid increases in human population lead doubting Th omas Mal indeed to predict in 1798 that the world would run short of diet add by the mid 19th Century. Paul R.Ehrilich, in 1968 predicted that famine would carry on in 1970s and 1980s.However various economists challenged them as various measures had been typeset in place to counter the foreseen problem. For instance, the massive awareness of green alteration lead to increase in fare production whose increment has been cooccurring with the rapid growth of the population. Analysts have however warned that despite the increase in food production, the prices are sky rocketing making its accessibility to those who have the means, and thus a larger number of human population experiencing malnutrition (Collinson. 002). Green transformation The introduction of Green R growth lead a 250% increase in food production for the year 1950 to 1984. However, the green revolution being support by fuel irrigation among other(a) things such as pesticides and fertilizers lead to knowing price s of food. therefore, despite the discovery saving the continent from dire famine, it has not merely addressed the accessibility of food by the poor. United Nation describe that as at 2005 approximately 850 million citizenry were facing malnutrition ascribable to lack of purchasing power of food.The high production of oil is an indicator that oil is crucial for daily survival. Farming is now mechanized where by bio-fuel is required which has had an effect on the prices of the farm produce (Freeman. 1974). Overpopulation Overpopulation is said to be a serious threat for the next generation. Generally is a evidence whereby there are more humans on earth than the earth can handle in terms of provision of enough resources that would identify them live happily and live it a fit place for the next generation users. However some countries provide incentives for people to increase their line of descent rate.This is said to have an impact of the growth of the economy and military se curity. former(a) critics have challenged such countries saying that the world is overpopulated and that failure to control sustain rate is in fact increasing death rate by default. On one hand, some politicians call for countries, especially MDCs to increase their population size to maintain their economic growth and military security. On the other hand, critics denote that one out of five people living here today is not properly supported and believe that the world is already limited in resources (Freeman. 974). Causes of Rapid Human Population Growth The world has seen a rapid increase in human population due to low death rate and increased birth rates. Above all the high skilled science and technological advancement have contributed in reduction of death rates. These innovations lead to increment in production and make out of food, the public health sector has been able to provide scour peeing and sanitation as easily as introduction of effective antibiotics and vaccines wh ich have contributed to prolonging human lives. In the past developing countries way of life was wanting.However, there has been the processes of education and global interactions that has lead to enhancement in their standards of living, and thus longitivity of lives. These innovations have seen discovery of treatment for diseases that once killed so many people such as measles, malaria, and flu (Zuckerman. 1996). Food Production and Distribution There also has been innovation in the agricultural sector, the biggest break through being genetically modified food as well as irrigation. For instance in the United states there was an increase in production from 631 million tones to 1. 65 billion tones between the years 1950 and 1984.This is an indicator that the amount of food produce increased tremendously that can cater for increasing human population (Hutchinson. 2008). These technologies has also allowed new breed of seeds, fertilizers and modern machinery which in turn has lead to expansion of agricultural sectors across the globe. Studies indicate the production of food has increased by 24% in the last 10 years. However, these expansion in food produce has not been witness evenly particularly in African Countries. Researchers have also confirm that there is no food shortage in the world, but equitable distribution should be considered.There are very many people particularly in African countries that do not have sufficient cash to buy food (Collinson. 2002). Public Health Survival of daily living is depended on radical needs such as true(p)ty shelter, food, and clean wet. Initially inaccessibility of clean water would contribute to wiping out children from cholera. Studies indicate that in the year 1990, less than 50% of the human populations were capable of getting access to safe crapulence water, however there has been in increase of accessibility of clean water to 75% afterwards.It was forecast that the accessibility to clean and safe drinking water w as to increase by 14% in the year 2000 end-to-end the world (Hutchinson. 2008). Housing Due to the rapid increase in human population, there has been the need to expand on housing. This has therefore resulted in evolution of urban centers which are highly populated. Due to high demand in housing, accommodation has become very expensive. As a result there has emerged high class, middle class, and low class societies.The poor are pressure to live in slums, whereby women and children are exposed to threats such as dishonour and exploitation. There have been strategies by various governments throughout the world to uproot poverty in vain. Cheap housing schemes have been designed by some governments unfortunately the number of the poor is appalling (Collinson. 2002). Consequences Studies have confirmed that the poorest countries have the largest number of human population. Research has also confirmed that there is a correlation between poverty and fertility as well as high child hood mortality rate.Therefore the people who enjoy high standards of living have low fertility rates, these people also have a longer life span as opposed to the poor as well as lower baby mortality rate. In a nutshell poverty and overpopulation are associates of increase of death and diseases. This is because lack of adequate sanitary housing and clean drinking water lead to health issues (Freeman. 1974). Developing countries have the highest number of human population as opposed to the developed countries. For instance one in every five persons in the Soviet countries live below the poverty line, as opposed to one of every eight person in America. want is said to have been caused by the acute increase in population after the end of the 2nd World War. Poverty has the lead to death of mankind. Instead of allowing poverty to persist, it is important to limit our number be-cause in wispy populations too many lack adequate food, water, shelter, education and employment. High fertility, wh ich has been traditionally associated with prosperity, prestige, and security for the future, now jeopardizes chances for many to achieve health and security (Hutchinson. 008). many a(prenominal) governmental and non governmental organizations have been set up to meet that the communicate population in the coming years will be simultaneous with production of food, water, heath care, technology, and education. For instance the development countries have put in efforts to ensure that both the social and economic conditions are at par. Programmes such as World Food Programme have been designed to ensure equitable distribution of food especially in developing countries.
