Essay about Can the World Sustain an Increasing Population

Countries in the world hold different attitudes to the population policy, some of them tend to delay the increase of population while others introduce policies to encourage childbirth. After centuries of continual growth, which started at the first industrial revolution, the global population reached over 7 billion individuals in 2013. Research by Ezeh, Bongaarts and Mberu (2012) states that increasing population is a threat to individuals and societies by bring problems based on unsatisfied demand. The â€Å"increasing population† in this essay can be defined as net rising in birth rate during a period, especially in the poor developing countries. This essay will argue that the world cannot sustain an increasing population. The reasons for†¦show more content†¦However, the same degree of pollution increases in cities with population of 10 million people is 3.13 parts per billion (NASA, 2013). The contribution to air pollution from surface-level NO2 is about a factor of five when population in cities increased from 1 million to 10 million people in China. According to Engelman (2009), falling human numbers is a powerful key to long-term environmental sustainability. Therefore it could be concluded that the world environment can hardly maintain an increasing population for its limited resources and probably pollution. Another reason for the world cannot continue to provide for increasing population is that rising rate of birth especially in poorest developing countries aggravates the trend toward greater inequality, which means the rich getting much richer while others are opposite. Ezeh, Bongaarts and Mberu (2012) found that in general, the growth of population is rapider in poorer countries than developed countries. For example, the World Bank points out that in sub-Saharan Africa where poverty headcount ratio fluctuated of 50% from 1981 to 2010, the rate of population growth is more than 2% per year. Poverty trend in here refers to people living on less than $1.25 a day.

Hoevel explains, â€Å"Overpopulation occurs when a population’s density exceeds the capacity of the environment to supply the health requirements of an individual† (Hoevel 1).
