Water is not only an essential for life and good health, but is a key driver of agricultural production, the economy and global development. However, water is a limited resource and with a largely growing population, water demands are continuously increasing at an uncontrollable and unsustainable rate.
There is vast variability of water supply over time as a result of seasonal cycles and inter-annual variation. The timing of these periods of high and low supply are largely unpredictable and therefore puts stress upon water management at the local, national and sometimes even the global scale (United Nations , N.D.).
Most developed countries have artificially overcome the unreliability of a continuous water supply through the building of various infrastructures such as desalination plants and dams (CSIRO , 2012). While these may assure for a reliable supply of water throughout the year these infrastructures do come with various risks and disadvantages such as high costs and negative impacts upon the environment and sometimes on human health (United Nations , N.D.).
Many less economically developed countries are finding that these solutions alone are not vast enough to overcome the increasing demands from various economic, climatic and environmental pressures (GCSE Bitesize , 2010). There has therefore been a demand for waste-water treatment and water recycling in order to counter the challenges of inadequate water supply (United Nations , N.D.).
Water use across the globe is extremely uneven with MEDC’s using far more per capita in comparison to LEDC’s (CSIRO , 2012). This can be seen in Figure 1 where A developed country such as Canada uses 1550m3 of water a year per capita and a developing country such as Bangladesh uses only ...

The article, Hidden Waters by Joanne Zygmunt describes how water is used in almost everything in the world. The article begins by stating agriculture soaks up the majority of all water and is depleting the limited supply. Roughly “70 percent of global freshwater withdrawals are for irrigation” (Zygmunt 8). Zygmunt, sates there are many unknown uses of water. For example, A hamburger contains “2400 litres of embedded water” (10). It is also stated the are different types of embedded water, “blue” and “green”. “Blue” is the water used in daily life. “Green” is water that is found underground (Zygmunt 11). Unlike other natural resources, there is no substitute for water. The effects of water shortage depend on water utilization, environment
Desalination plants overall could be a huge benefit to society for its high quality of water and intuitive water treatment techniques, however the big environmental impacts and high costs to produce water at a desalination plant makes it unfavorable to most communities especially the poorer communities. Although costs for the production and upkeep for a desalination plant has been going down while the technology of it rises, the only true benefit for having a desalination plant would only come into affect when it is near a body of ocean, such as Tampa Bay Water. All in all desalination plants could soon be the face of future water treatment plants and water sources, but for the present time it is still only a niche water source.
Growing scarcity in nearby water resources is the issue addressed in “Will Water Become the Chief Commodity of the 21st Century?” by Christa Marshall. The thesis of this essay is will water become the chief commodity of the 21st century? The author’s main claim is the world faces a growing number of challenges surrounding water and her sub claim is these examples underscore the many options available to alleviate a growing global water crisis. The author argues where water demand will exceed available supplies could rise forty percent. Her conclusion is businesses need to gain a better sense of how much water they are actually using.

In the world, about two billion people depend on wells for their clean drinking water. Almost all women and children spend at least 6 hours a day getting water for their families. One out of every ten people don’t have clean water. Some people in third world countries walk about three to four miles to get clean water to drink. The global water crisis is the number one cause of death in the world.
In our generation of new technologies and high civilization it is hard to believe that our World is in Water crisis. This crisis is affecting not only low-developed parts of the world but also it affects high-developed countries, about one third of the humanity suffers from the scarcity of water (Molden 2010). One of the main causes of it is overpopulation. In increasing water demand water sources which we have now are not able to renew themselves. Another factor of water scarcity is not economized water consumption. Nowadays most of countries are beginning to realize that solving the problem of scarcity of water is very crucial. One of them is Mexico where water shortage is the national problem.
In California, 2013 marked the direst year on record. Rainfall precipitation statewide was 7 inches, while the previously recorded driest year dates back to 1898, with 11.6 inches. So it was no surprise that on January 27th 2014, Governor Brown declared California in a drought state of emergency and directed state officials to take action (DWR). The Department of Water Resources has reduced water allocations from the State Water Project to zero percent, affecting 29 public water agencies. Not only has the current drought impacted California on a political level, it has evoked panic in the public, especially farmers, who rely on a steady water supply to make their living. There is an urgent need for a solution, but little agreement on an action. Conservation approaches have always been in play, however another proposed solution involves the production of potable water through the process of desalination.
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
Before delving in to what is actually wrong with seawater desalination plants, it is important to establish that there are plenty of alternatives available. One of the best alternatives is to adopt more efficient practices, such as conservation of water, and recycling storm water and grey water (from washing machines and bathrooms...
Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.
