If the whole world agreed on and adopted a policy so that only 2. From toenergy use was increasing at a rate of 2. We must avoid letting humans numbers continue to increase to the limit of the Earth's natural resources and forcing natural forces to control our numbers by disease, malnutrition, and violent conflicts over resources.
If they do, the impact of urban population growth could be much larger. This situation is typical of many rivers and lakes in developing countries WHO, Approximately 3, years are needed for the natural reformation of topsoil to the mm depth needed for satisfactory crop production.
A total of cities dump untreated sewage and partially cremated bodies directly into the sacred Ganges River NGS All of the chemical and nuclear energy that society consumes ultimately winds up as heat in the environment.
Attention is now focused on next month's Earth Summit in Johannesburg, the most important environmental negotiations for a decade. For instance, it might be possible to feed the current 6 billion people a minimal but nutritionally adequate diet, if all food produced in the world was shared and distributed equally Cohen, Share via Email Earth's population will be forced to colonise two planets within 50 years if natural resources continue to be exploited at the current rate, according to a report out this week.
It is clear to all of us that the planet is not expanding.
This practice, however, increases dependency on the limited fossil fuels stores necessary to produce these fertilizers. Measurable shortages of fertile land, water, and fossil energy now exist in many regions of the world Worldwatch Institute, ; WRI, ; WRI, 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.
Neither is now sufficient for domestic needs, and supplies are imported in increasing yearly amounts DOE, ;BP, ; Youngquist, Only when wealthier groups are prepared to adopt low-carbon lifestyles, and to permit their governments to support such a seemingly unpopular move, will we reduce the pressure on global climate, resource and waste issues.
Youngquist reports that current oil and gas exploration drilling data has not borne out some of the earlier optimistic estimates of the amount of these resources yet to be found in the United States.
There is only so much space on Earth, not to mention only so many resources — food, water and energy — that can support a human population.
Agriculture commands more water than any other activity on the planet. As populations increase in size, risks to health and productivity grow as well, especially in areas where sanitation is inadequate.
It would indeed be a wonderful achievement to see these technologists produce crops without water!. So a world with a human population of 11 billion might put comparatively little extra strain on our planet's resources.
But the world is changing. Low-income urban centres may not continue on low. Global Footprint Network data shows that humanity uses the equivalent of planet Earths to provide the renewable resources we use and absorb our waste. 1 If all 7+ billion of us were to enjoy a European standard of living - which is about 60% the consumption of the average American - the Earth could sustainably support only about 2 billion people.
So a world with a human population of 11 billion might put comparatively little extra strain on our planet's resources. But the world is changing. Low-income urban centres may not continue on low. Unfortunately, most individuals and government leaders appear unaware, unwilling, or unable to deal with the growing imbalances between human population numbers and the energy and environmental resources that support all life.
The population of our planet will quickly reach a point where there will not be adequate amount of resources to support life on Earth. Population control must be enforced to avoid such a catastrophic occurrence.
Many economic, social and environmental problems are either affiliated with or. Unfortunately, most individuals and government leaders appear unaware, unwilling, or unable to deal with the growing imbalances between human population numbers and the energy and environmental resources that support all life.Earths resources can no longer support human population
