The world's ocean covers about 70% of the Earth's surface. It is use to produce
us many things. It is more than a place to swimming, sailing and other
recreation. The ocean serves as a source of energy, raw materials and most of
all food like fish and seaweed. In this essay I will talk about "What are our
ocean resources and the importance of the oceans in the future."

First, our largest resource in the ocean is food. There are two different kinds
of food in the ocean, such as marine plants and marine animals. These two kinds
of resources are reborn resources and it will never be end. For marine plants we
have the algae's family, like seaweed. During ebb tide, you can find the seaweed
between rocks. For the marine animals we have fish and shrimp. The fish and
shrimp are always moving around the ocean and follow the ocean currents.

What is ocean current? It is a movement of ocean thatcan buring the fish to
other places. There are two kinds of circulation create the currents in the
ocean. They are (1) wind-driven circulation and (2) Thermohaline circulation.
Wind-driven circulation result from the wind sets the surface waters into motion
as currents. The currents generally flow horizontally-that is parallel to the
earth¡¦s surface. The wind mainly affects only the upper 100 to 200 meters of
water. However, the flow of wind-driven currents may extend to depths of 1,000
meters or more.

Thermohaline circulation produces great vertical currents' hat flow from the
surface to the ocean bottom and back. The currents largely result from
differences in water temperature and salinity. The currents move sluggishly from
the polar regions, along the sea floor, and back to the surface. In the polar
regions, The surface waters become colder and saltier. Being colder and saltier
makes these waters heavier, and they gradually flow back toward the surface and
replace the surface waters that sink. For example, as a warm ocean current and a
cold ocean current meet together, The warm water will always follow cold water
and moving around the ocean. The most important is the plankton does not like to
stay in the cold place. They will follow the warm current. As the result the
small fish like shrimp that eats plankton, will follow the plankton. Similarly
the bigger fish that eats small fish and shrimp will just follow also and these
