Because only three percent of the world's water is potable. And with man-made pollution that number is going down.
Desalination is a process that removes mineralsfrom saline water. More generally, desalination may also refer to the removal of salts and minerals,[1]as in soil desalination, which also happens to be a major issue for agricultural production.[2]Salt water is desalinated to produce fresh water suitable for human consumption or irrigation. One potential by-product of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use. Along with recycled wastewater, this is one of the few rainfall-independent water sources.[3]Due to relatively high energy consumption, the costs of desalinating sea water are generally higher than the alternatives (fresh water from rivers or groundwater, water recycling and water conservation), but alternatives are not always available and rapid overdraw and depletion of reserves is a critical problem worldwide. Quoting Christopher Gasson of Global Water Intelligence, "At the moment, around 1% of the world's population are dependent on desalinated water to meet their daily needs, but by 2025, the UN expects 14% of the world's population to be encountering water scarcity. Unless people get radically better at water conservation, the desalination industry has a very strong future indeed."[4]Desalination is particularly relevant in dry countries such as Australia, which traditionally have relied on collecting rainfall behind dams to provide their drinking water supplies. According to the International Desalination Association, in June 2011, 15,988 desalination plants operated worldwide, producing 66.5 million cubic meters per day, providing water for 300 million people.[5]This number has been updated to 78.4 million cubic meters by 2013,[4]or 57% greater than just 5 years prior. The single largest desalination project is Ras Al-Khair in Saudi Arabia, which produced 1,025,000 cubic meters per day in 2014,[4]although this plant in Saudi Arabia is expected to be surpassed by a desal plant in California.[6]The largest percent of desalinated water used in any country is in Israel, which produces 40% of its domestic water use from seawater desalination.[7]
An Engineering Portfolio is a website or document that highlights examples of your work and projects. ... Portfolios increases one's awareness of their skills and abilities; it is another way to connect in-and-out of classroom learning with real world applications. Show off your work, your projects, and your passions
Silicon was discovered by a Swedish scientist. Silicon itself is not found in one nation, but can be found all over the world (usually mixed in other substances such as clay or mica).
If you are talking about World War I, then:The railroad was the new technology that was considered the most important tool for a nation to mobilize. The railroad was capable of transporting troops, along with their weapons and supplies, to the front in the opening phase of the war. Many observers regarded the railroad as the key to victory or defeat.

Desalination is the removal of salt from water. Desalination occurs when saltwater evaporates and forms clouds and rain. This is a natural process that is important for all land plants and animals, and there's no reason to try and prevent it.
Iran, along with Saudi Arabia, is the world leader in oil and petrolium. The nation floats on a reserve of oil.
