The seas provide
The sea is a storehouse of food, medicines, and minerals. Marine fish and other animals provide 14 per cent of the world' s animal protein. Only 70 per cent of this is consumed by humans - the rest goes to make animal feed and fertilizer. Some 500 marine species yield chemicals which could help treat cancer. More than 40 countries, including Australia, Brazil, Egypt, Malaysia, Nigeria, and Trinidad and Tobago, obtain oil and natural gas from the seabed. Many others dredge for sand and gravel to make concrete.
