The world's largest seas include Philippine Sea, Coral Sea, arabian sea, South China Sea, Weddell Sea,Caribbean, Mediterranean Sea, Tasman Sea, Bering Sea, Bay of Bengal etc.

We may wonder how can make sea as future granaries?

Although rice and wheat cannot be grown in the ocean, fish and shellfish in the ocean can provide delicious and nutritious protein food for human beings.

Mr. Wang, who is responsible for design at gmtlight, said that protein is the most important substance that makes up an organism, and it is the basis of life.

Can Sea Be "granary" of Mankind?

Today, only 5 to 10 percent of the proteins consumed by humans are supplied by the oceans.

Anxiously, since the 1970s, the amount of marine fishing has been stagnating, and many species have been depleted.

In nature, there are countless food chains. In the ocean, there are shellfish with algae, and there are small fish and even big fish with shellfish... The total area of the ocean is more than twice that of the land, and most of the world's countless fisheries are in the offshore waters mentioned above. This is because algae need sunlight, silicon, phosphorus and other compounds to grow. These conditions are only available near the coast of land.

Can Sea Be "granary" of Mankind?

Nowadays, a kind of algae has been developed to reproduce in the sea, producing more than 20 tons of protein per hectare of sea surface. Marine surveys show that silicon and phosphorus are abundant in the deep water below 1000 meters, but they can not float on the warm surface. Because of the effect of natural forces, some deep water automatically rises to the surface layer, which makes these waters a rare fishing ground with dense algae and fish.

It is entirely possible to ask for more protein from the sea. In the early stage, we should protect the sea and make rational use of it. If so, the ocean could be the "granary" of mankind.

Can Sea Be "granary" of Mankind? The answer is "yes".
