Many people may be wondering why Is water so essential In life, there’s an endless reasons for the importance of water. To say a few would be, 75% of human body is composed of water; we need water for our daily basis such as bath, and water is widely used agriculturally, economically and commercially. But the most Important reason of all Is that water is required for life to occur, biological evidence furthermore support that the first sign of life begins with water, no water equals no life. Water Is also Involved In many chemical reactions In our body, without It our odd cannot function.

Water is also involved in many chemical reactions in our body, without it our body cannot function.

Water is singly the most important element to the world as a whole. It is the lifeblood of the environment, essential to the survival of all living things whether it is a plant, an animal or humans (Environment Canada, 1996). It Is a powerful resource that we cannot afford to live without, so we must do everything possible to maintain its quality and the life inside it for today and the future. It creates, sustains and has the ability to take life. However, we as humans have lost respect for the basic element to our existence.

We dump sewage, chemicals and garbage into our own water and, exploit the fish and animals living in the waters almost or to the point of extinction. We pollute and ravage the oceans without any regard for what the outcome to our ecosystem could and will be if it continues. As humans, we are primarily composed of water. Our blood, which is our means of transporting food and waste, and also regulates our temperature, Is made up of 83 percent water _ It Is an unquestionable fact that we need water, Just like everything else that exists on this planet.

Water’s harmless and pure nature creates and sustains life but when exploited for immemorial uses It becomes damaged by pollution and the ecosystems Inside It are hurt, effecting all life on the planet. The water resources of the world are a raw material, Just like minerals and gas, which industries want to use to make money, but In the process it Is Industries that are exploiting and polluting our waters, damaging them for all future generations. Through industry we, as humans, are killing the oceans by over-fishing, destroying coral reefs and polluting them with sewage and garbage.

Although businesses do have the right to the use of the oceans and waters f the world to profit from Just the same as any other business, it is the negative manner in which they use our waters that results in the destruction of habitats and species In and around the water and the large Continuo Water resources are sources of water that are useful or potentially useful. Uses of water include agricultural,longitudinal, household, recreational and environmental activities. The salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. L] The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. [2] Fresh water is a renewable resource, yet the world’s supply of groundwater is steadily decreasing, with depletion occurring most prominently in Asia and North America, although it is still unclear how much natural renewal balances this usage, and whether ecosystems are threatened. [3] The framework for allocating water resources to water users (where such a framework exists) is known as water rights.

Agricultural[edit] It is estimated that 70% of worldwide water use is for irrigation, with 15-35% of irrigation withdrawals being unsustainable industrial[edit] A power plant in Poland It is estimated that 22% of worldwide water is used in industry. [6] Major industrial users include hydroelectric dams, thermoelectric power plants, which use water for cooling, ore and oil refineries, which use water in chemical processes, and manufacturing plants, which use water as a solvent. Water withdrawal can be very high for certain industries, but consumption is generally much lower than that of agriculture.

Household[edit] Drinking water It is estimated that 8% of worldwide water use is for household purposes. 6] These include drinking water, bathing, cooking, sanitation, engendering. Basic household water requirements have been estimated by Peter Click at around 50 liters per person per day, excluding water for gardens. Drinking water is water that is of sufficiently high quality so that it can be consumed or used without risk of immediate or long term harm. Such water is commonly called potable water.

In most developed countries, the water supplied to households, commerce and industry is all of drinking water standard even though only a very small proportion is actually consumed or seed in food preparation. Recreation[edit] Whitewater rapids Recreational water use is usually a very small but growing percentage of total water use. Recreational water use is mostly tied to reservoirs. If a reservoir is kept fuller than it would otherwise be for recreation, then the water retained could be categorized as recreational usage.

Release of water from a few reservoirs is also timed to enhance whitewater boating, which also could be considered a recreational usage. Other examples are anglers, water skiers, nature enthusiasts and swimmers. Recreational usage is usually non-consumptive. Golf courses are often targeted as using excessive amounts of water, especially in drier regions. It is, however, unclear whether recreational irrigation (which would include private gardens) has a reliable data.

Additionally, many golf courses utilize either primarily or exclusively treated effluent water, which has little impact on potable water availability. Environmental[edit] Explicit environment water use is also a very small but growing percentage of total water use. Environmental water may include water stored in impoundments and leased for environmental purposes (held environmental water), but more often is water retained in waterways through regulatory limits of abstraction. 13] Environmental water usage includes watering of natural or artificial wetlands, artificial lakes intended to create wildlife habitat, fish ladders, and water releases from reservoirs timed to help fish spawn, or to restore more natural flow regimes[14] Like recreational usage, environmental usage is non-consumptive but may reduce the availability of water for other users at specific times and places. For example, water lease from a reservoir to help fish spawn may not be available to farms upstream, and water retained in a river to maintain waterway health would not be available to water abstractors downstream.

Water pollution is one of the main concerns of the world today. The governments of numerous countries have striven to find solutions to reduce this problem. Many pollutants threaten water supplies, but the most widespread, especially in developing countries, is the discharge of raw sewage into natural waters; this method of sewage disposal is the most common method in underdeveloped countries, but also is prevalent in quasi-developed countries such as China, India, Nepal and Iran.

Sewage, sludge, garbage, and even toxic pollutants are all dumped into the water. Even if sewage is treated, problems still arise. Treated sewage forms sludge, which may be placed in landfills, spread out on land, incinerated or dumped at sea. [21] In addition to sewage, Nippon source pollution such as agricultural runoff is a significant source of pollution in some parts of the world, along with urban stemware runoff and chemical wastes
