The survival of this planet is based on this huge mass of water scattered over the Earth.

The word of Ocean in Latin languages was adopted from Greek word “Okeanos” who was the Greek god of Seas and Waters. In the last six years the World Oceans have undergone an unprecedented degradation, pollution, destruction, over-fishing. Time has come that six billion people of Earth should now definitely think about this excellent gift of mother ‘Nature” that has a fragile Echo-system and make a difference. The difference should also come from man, not only from a single person, but a significant difference that should come from every one of us. Last year, the first “World Ocean Day” was celebrated on the occasion of Earth Summit, in Rio-de-Janeiro, Brazil to remind the people of the Planet that the Oceans surrounding their lands are in danger.

Oceans are 72% of Earth surface, and no doubt, we as a human being are surviving here with other creatures also. This whole planet is not owned by human only, but the Earth belongs to every creature, either they are human or not. The survival of this planet is based on this huge mass of water scattered over the Earth. Our planet is “Blue” in the entire Solar System because of these blue waters. This wonderful source of water known as sea or ocean is globally interconnected and is now at stake, because of the growing human population. Every man either living besides the sea or living miles away is affecting the Oceans, and at last, six billion people of the world living on land have created a havoc on 5 big oceans of the Earth who are holding combined the water equivalent to1370 million km³.

World Oceans are scattered over an area of 361 million km² bearing the salty waters. Average depth of an ocean is estimated around 3790 m, while the deepest place on all oceans is measured at the Mariana Trench located in the Pacific Ocean with a maximum depth of 10,923 meters. It is also considered as the deepest point on Earth. It’s God will that the life exists even in the deepest trenches, where the pressure of water reaches one tonne on every square centimeter. Most beautiful scenes also exist under these deep waters. There are mountains, hot springs, beautiful vegetation, colorful creatures of sea. In an analysis study, it was found that most of micro-organism found under these deep spots is not found on Earth.

At some places, oceans have been linked by the man through canals. These important canals are Suez and Panama Canals. Suez Canal links the Mediterranean Sea with Indian Ocean via Red Sea, while the Panama Canal links the Pacific Ocean with the Atlantic Ocean. Another Important ship-canal is St. Lawrence Seaway.

Almost half of the world’s human population is living within 80 miles of the Sea Coasts. With a glance you can look at the benefits, oceans are providing to us. A sea behind the limits of our land provides us food, energy, a good quality air, pleasant climate, sporting, leisure and economical activities.

In return what we are giving to seas include extremes such as: untreated industrial and human-waste pollution and greedily depleting its marine-life resources.

The beautiful Oceans provide us Economy, Ecology and Climates (EEC)

Economy:  The oceans are essential to transportation. A huge portion of the world's goods are moved by ship between the world's seaports. Early man used to sail over the surface of oceans, but the gradual industrialization brought him the power of under-water sailing. Submarines have become important tool of travel not only within the warm waters but also beneath the ice-bergs of polar regions. This under-water travelling power has been used as an important tool by the scientist, explorers and military-men to look at ocean-treasures and exploit its worth. To the ordinary man world’s oceans provide vast range of delicious marine-food and sustenance to fisherman.

Ecology:   The oceans are home to assorted life, such as small colorful fish to huge whales. Oceans are the habitat of 3/4th of the world’s known animal species. World’s largest mamals are found in Oceans.

Climate:  The climates of the land are greatly affected by the Seas. Most of the carbon dioxide generated over the land is absorbed by the oceans partly exchanging it with the oxygen. Important winds blow over these vast oceans thus moving some big ocean currents and enabling them to travel thousands of kilometers. These currents thus transfer warm or cold air and precipitation to coastal regions, where they are mixed up with the inland winds and are carried out into the main land. The winds carrying the moistures from the seas become the cause of seasonal rains in many parts of world. These...
