Acclaimed hermit Henry David Thoreau once wrote that humans have plenty of space. “Our horizon is never quite at our elbows” (Thoreau, 49). But is this really true? The U.S. Census Bureau's international population clock estimates the global population at slightly over 8.6 billion people. According to the UN, the world population increased by 46.2 percent between 1960 and 1980. This means that the estimate of the population is growing at .7% annually, with a doubling time of 100 years was incorrect, in actuality the rate was 2.08 % with a doubling time of only 35 years (Choucri, 5-6). If it's difficult to imagine how many people that really is, try this visualization: If every person in the world got together and stacked one on top of the others' shoulders, it would create a ladder to the moon. As large as our numbers are, global population is growing at an exponential rate, and we are seeing more and more environmental problems because of this. One phenomena of recent population growth is that many people are moving from rural to urban areas. More people in these urban areas means more traffic, more industrial development.
Natural environment is a topic that gets thrown around in many different debates. More controversial is the debate as to whether or not human population—i...

- ... The degradation in human life causes diseases transferring from animals and cause lethal epidemics (Ehrlich and Ehrlich 2012). It’s agreed that, economy, social, and political factors are overlap in term of population growth. To supply the demand of growing population, the agricultural production must be increased “70-100 % by 2050”. This increase will be associated with increasing energy consumption and demands on the free market based economy. Agriculture requires more fossil fuel and lands for farming....

- “We are burdensome to the world, the resources are scarcely adequate for us.” Tertullian, a philosopher from the third century had said this about our world when the population was mere 200 million. This statement can be taken two different ways. The first would be to think that our resources are limited and we need to be worried. The second would be to say people have been worried about overpopulation forever but everything seems to have worked out. Now there may only be two sides to Tertullian’s statement but the issue he touches base with certainly can be extended beyond that.... [tags: Overpopulation, Environment]

- Humans have greatly impacted the global environment. Throughout the course of history, human populations have rapidly increased. Especially in Africa, these numbers have reached extraordinary proportions. Out of all the continents in the world, Africa’s population is increasing the most. The type of growth here is exponential. “Overpopulation is a condition when an organisms numbers exceeds the carrying of its ecological niche.” The growth rate of a population is equal to the birth rate minus the death rate....

- Jacques-Yves Cousteau once said, “Overconsumption and overpopulation underlie every environmental problem we face today” (“Population,” Internet). With the current statistics, Jacques could not be more accurate. Every second, 4.2 people are born and 1.8 people die, which would be a net gain of 2.4 people per second (“Population,” Internet). At this steady rate, the environmental health is spiraling downwards, and it is safe to assume humans are responsible for this. As the population increases, harmful effects on the land, water, and air also do.... [tags: environmental health, megacities, overpopulation]

- Stories of current times could sound surreal to citizens of the year 2552. Tales of water coming out of the ground, fuel sources called fossil fuels, or vast areas covered in trees would all be stories around the virtual campfire. Lands once known as Africa have become uninhabitable to even the most resilient organisms. At the poles, it is so cold that the fuel lines in vehicles freeze in eleven seconds. The descendants of seven billion people currently inhabiting this world would be faced with hard times if we fail to take action.... [tags: Overpopulation, Environment]
