The ocean contains many treasures. Both which are explicit and implicit. The implicit are the ones we are currently exploiting and the explicit are the ones that hold a large potential for exploitation by our future generations.
Fishing has been practiced for over thousands of centuries. Nutritionally fisheries provide almost 16% of the world's totally protein. Today 90 million tonnes of fish are caught in the oceans each year.
The commercial fishing industry has is not only obtained fish for us but also things of ornamental value and fish oil. Many countries are involved in aquaculture, an example is fish farming. Here fresh water or salt water species can be grown under controlled conditions.
It is a fact that sea contains gold four hundred times more than land. Gold has been mined in the Alaskan sea. Did you know that if all the gold in the sea is distributed to people on the Earth then everybody would have more than 4kgs of gold each?
The compressed dead bodies of the sea creatures over the years have made huge oil reserves. It is interesting to note that over one fifth of earth's oil demand is being met through oil rigs in the oceans. Norway is one of the biggest offshore oil producers.
The sea is also not just a large store of oil reserves that can be used to generate power; the tides can be harnessed to meet the earth's energy needs too. The world's first energy plant was built in France in River Rance. Tidal energy is eco friendly and a renewable source of energy that does not harm the environment nor deplete earth's resources.
We obtain salts from the sea too. 66 million tonnes are taken out each year. It is equivalent to three Egyptian pyramids.
Icebergs which are found in the North and South Poles are seen as huge reserves of freshwater. They are towed away by boats and could solve the problems of water crisis in drought and famine. They could be prevented from melting by wrapping them in huge layers of plastic.
