ocean+food

The ocean provides many different types of supplies.One of the greatest supplies is food.Seafood is a very good for health because it has many proteins.We get these proteins by fishing or through aquaculture.Fishing is a very important industry.When the ocean is overfished or overharvested ther fish population can collapse.The collapse may cause damage to the ecosystem.The government has managed laws to prevent a collapse to occur.Aquaculture is the raising of aquatic plants and animals for human use or consumption. Catfish,salmon,oysters and shrimp grow on large aquatic farms.A major problem for aquaculturists is that the ocean farms do pollute the water.An ocean farm could produce more food than an agricultural farm of the same size does.For example, in agriculture, only the top layers of soil can be used. On the other hand, ocean farms use a wide amount of depths to produce food.The rich nutrients in the bottom of the water may move to the surface and be used as a way of fertilizing aquatic farms.
