Resources of the oceans: their types and significance
Now, when global changes are taking place all over the planet, the oceans play a huge role in the life of mankind, more than ever. After all, it contains such wealth, which, with rational use and ensuring their reproduction, is almost endless.With the right approach, the resources of the oceans can provide industry with the necessary raw materials, and the rapidly growing population of the planet — food and fresh water — can save them from an energy crisis. All of his inexhaustible wealth is divided into several types.
World Ocean Resources: their main types
1. Sea water. This is the first and main resource. First, it identifies 75 important chemical elements (bromine, potassium, magnesium, uranium, and others). Of the total salt production in the world, the proportion obtained from ocean waters is 33%. They are also the source of some metals (including silver and copper), which are necessary for industry.In addition, fresh water can be obtained from sea water. And this is important, if we take into account its deficit in many hot countries.
2. Mineral resources of the oceans. This is not only what is directly in its waters, but also what is hidden in the depths. At the bottom of the ocean lies a lot of minerals. Some of them - platinum, gold, and sometimes precious stones - are washed away to the coasts of the continents. The vast submarine plains of the World Ocean are predominantly covered with iron-manganese nodules. They are a mixture of many metals: cobalt, titanium, nickel, vanadium, copper. But prevails among them, of course, manganese and iron.
3. Energy resources of the oceans. This is the temperature regime and the movement of its waters. At this time, the development of the ebb and flow energy, begun in the Middle Ages, continues. Scientists are developing projects for the most appropriate use of the energy of currents, waves and surf.
4. Fuel resources of the World Ocean. In the depths of it in large quantities formed and accumulated deposits of oil, coal and natural gas. These combustible minerals are the most widely used types of fuel in the modern world.The need for them in most countries is increasing every day, since not all regions are provided with them equally. The exploration work carried out has shown that it is the bottom of the World Ocean that can serve as the main source of gas and oil production.
5. Natural resources of the oceans. The total volume of its biomass, consisting of algae and animals, is 35 billion tons. This is enough to feed 30 billion people. In order for the food resources of the World Ocean to remain inexhaustible, they must be used very carefully, and in no case do not exceed the maximum catch limit for fish, pinnipeds and whales. One of the ways to increase its biological productivity is to artificially breed living organisms in coastal zones.
Additional value of the World Ocean
It serves not only as a storehouse of all kinds of resources, but also as a road connecting entire continents. Most of the traffic between countries is provided by sea transport. Also, the physical and chemical properties of ocean waters, the influence of living organisms inhabiting them, contribute to the processing of almost all waste entering it, thereby supporting the ecosystems of the planet.
