The Pacific Ocean is the largest and oldest on earth. There are many corals at the bottom of the ocean. A large number of corals are associated with the suitable warm temperature of the water. The ocean is full of fish. Shellfish and various algae are grown on the seabed in some countries. Human economic activity has led to the pollution of ocean waters and to the extermination of certain animal species. On the verge of extermination are seals, whales. Their fishing is currently limited. A great danger to the ocean is water pollution by oil, industrial waste.
