Overpopulation is the state whereby the human population rises to an extent exceeding the carrying capacity of the ecological setting. In an overpopulated environment, the numbers of people might be more than the available essential materials for survival such as transport, water, shelter, food or social amenities.
Indeed our very success going forth and multiplying, paired with our ability to extend our life expectancy, has meant that we are perpetually pushing the limits of the resource base that supports us. Today our population tops seven billion. While better health care and medicine along with advances in food production and access to freshwater and sanitation have allowed us to feed ourselves and stave off many health ills, some so-called Neo-Malthusians believe we may still be heading for some kind of population crash, perhaps triggered or exacerbated by environmental factors related to climate change.
Of course, the immigration that continues to fuel population numbers in developed countries is coming from somewhere. Also fertility rates in Africa continue to be among the highest in the world, as many countries there are growing fast, too.
Poverty and health problems due to poor sanitation, lack of access to food and water, the low social status of women and other ills continue to cripple these regions. Globally, the United Nations estimates that the number of humans populating the planet in will range from as few as 6.
Meanwhile, other researchers confirm the likelihood of world population levels flattening out and starting to decline by according to the lower UN estimate.
To wit, the Austria-based International Institute for Applied Systems Analysis IIASA recently unveiled research showing that if the world stabilizes at a fertility rate comparable to that of many European nations today roughly 1.
It is difficult to say which way the global population pendulum will swing in centuries to come, given ever-changing cultural, economic and political attitudes and the development demographics they affect. As such the jury is still out as to whether human overpopulation will become a footnote in history or the dominant ill that stands in the way of all other efforts to achieve sustainability and a kinder, gentler world.Human overpopulation is among the most pressing environmental issues, silently aggravating the forces behind global warming, environmental pollution, habitat loss, the sixth mass extinction, intensive farming practices and the consumption of finite natural resources, such as fresh water, arable land and fossil fuels, at speeds faster than their rate.
But overpopulation is seldom discussed as a public health issue. Just how many of us are there and how is our rising population affecting human health? The Effect of Overpopulation on Public Health.
Erika Gavenus | August 23, | Leave a Comment. We humans are on a similar trajectory and only concerted population reduction before we. Human Overpopulation: Still an Issue of Concern? The jury is still out as to whether the growth of human population is a positive factor or a dominant ill that could spell environmental and social.
Fresh Water and Overpopulation. Fresh water is one of the biggest concerns with overpopulation, and this poses a huge environmental threat.
The government sustains the rights to fresh water, whether it is from melting snow pack in the mountains or a freshwater lake.
Different cities have what is known as “water rights” from a certain mountain area’s. Jun 08, · Debaters. Overconsumption Is a Grave Threat.
Fred Pearce, author, "The Coming Population Crash" We have to radically change how we produce what we consume. Overpopulation. It is a word that makes politicians wince, and is often described as the "elephant in the room" in discussions about the future of the planet.
