Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water. A human body can survive 8-14 days without water depending on the person. First of all our very existence will be in danger in the absence of fresh drinking water. Besides we will not get the much needed source of irrigation for

There has been a 44% decline over the last 20 years in the Florida Keys‚ and up to 80% in the Caribbean alone. Coral is very sensitive to changes in seawater. It requires the temperature is moderate but clean without sewage. As long as there is enough time‚ coral reefs can naturally recover a little natural damage‚ and sometimes even make the coral reef biological richer. Human activities on coral can

Uranium 00•Uranium is a very heavy metal which can be used as an abundant source of concentrated energy. •Uranium occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the Earth’s crust as tin. Uranium occurs in seawater‚ and can be recovered from the oceans. 571508953500•Uranium was discovered in 1789 by Martin Klaproth‚ a German chemist‚ in the mineral called pitchblende. It was named after the planet Uranus‚ which had been discovered eight years earlier. •Uranium

When it is used to generate electricity‚ it is known as a wind turbine generator. Besides milling grain and irrigating farmland‚ windmills developed from the 15th century to the 19th century were adapted to a variety of tasks‚ including pumping seawater from land below sea level‚ sawing wood‚ making paper‚ pressing oil from seeds‚ and grinding many different materials. By the 19th century the Dutch had built about 9000 windmills. In 2006 the United States became the world’s third largest producer
