Agency for International Development USAIDan independent organization that provides economic, development and humanitarian assistance around the world in support of the foreign policy goals of the United States, predicts that byone-third of all humans will face severe and chronic water shortages. Needless to say, water is of primary importance to our survival, and protecting access to and the quality of fresh water supplies will likely become more and more of a challenge in the coming years. With world population expected to increase as much as 50 percent over the next half century, analysts are indeed worried that increasing demand for water, coupled with industrialization and urbanization, will have serious consequences both for human health and the environment.

The figure is based on a UN report which calculated the economic value of services provided by ecosystems destroyed annually, such as diminished rainfall for crops or reduced flood protection. The problem is also getting worse as populations and consumption keep growing faster than technology finds new ways of expanding what can be produced from the natural world.
This had led the report to predict that byif nothing changes, mankind would need two planets to sustain its lifestyle. Its capacity to support a thriving diversity of species, humans included, is large but fundamentally limited. Ultimately this loss threatens human well-being.
For the first time the report also contains detailed information on the "water footprint" of every country, and claims 50 countries are already experiencing "moderate to severe water stress on a year-round basis". It also shows that 27 countries are "importing" more than half the water they consume - in the form of water used to produce goods from wheat to cotton - including the UK, Switzerland, Austria, Norway and the Netherlands.
Based on figures fromthe index indicates global biodiversity has declined by nearly a third since Breakdowns of the overall figure show the tropical species index fell by half and the temperate index remained stable but at historically low levels.
Divided up another way, indices for terrestrial, freshwater and marine species, and for tropical forests, drylands and grasslands all showed significant declines. Of the main geographic regions, only the Nearctic zone around the Arctic sea and covering much of North America showed no overall change.
Over the same period the ecological footprint of the human population has nearly doubled, says the report. At that rate humans would need two planets to provide for their wants in the s, two decades earlier than the previous Living Planet report forecast just two years ago.
This figure is "conservative" as it does not include the risk of a sudden shock or "feedback loop" such as an acceleration of climate change, says the report.
The global average consumption was 2. The UK, with an average footprint of about 5.The world is heading for an "ecological credit crunch" far worse than the current financial crisis because humans are over-using the natural resources of the planet, an international study warns.
Overpopulation is the world's top environmental issue, followed closely by climate change and the need to develop renewable energy resources to replace fossil fuels, according to a survey of the.
The Living Planet report calculates that humans are using 30% more resources than the Earth can replenish each year, which is leading to deforestation, degraded soils, polluted air and water, and dramatic declines in numbers of fish and other species.
The problems with the world's water supply, from distribution and overdevelopment to bacteria and diseases about the world’s dwindling water supplies, thinks it can be done if world leaders.
Dwindling Resources in a World of 9 Billion As a result, crucial natural resources will dwindle. This article looks at four that will be much harder to come by in the future.
Natural resources are those resources that occur within the environment in their original and natural form, undisturbed by humanity. to reduce air pollution as polluted air degrades the environment and can enter our body and can cause health related problems.
