Seas and oceans provide various types of resources to human beings and habitats to numerous species of plants and animals. They play very important roles in the economy of a nation and its people. Still, the marine and coastal ecosystems are under severe stress due to human activities. Ocean Resources

The ocean is one of Earth's most valuable natural resources. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. It's used for transportation—both travel and shipping. It provides a treasured source of recreation for humans. It is mined for minerals (salt, sand, gravel, and some manganese, copper, nickel, iron, and cobalt can be found in the deep sea) and drilled for crude oil.

Explore them in greater detail to understand why we must keep the ocean healthy for future generations.

The oceans have been fished for thousands of years and are an integral part of human society. Fish have been important to the world economy for all of these years, starting with the Viking trade of cod and then continuing with fisheries like those found in Lofoten, Europe, Italy, Portugal, Spain and India. Fisheries of today provide about 16% of the total world's protein with higher percentages occurring in developing nations. Fisheries are still enormously important to the economy and wellbeing of communities.
