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

fish...

Sound in Alaska. It spilled over 11 million gallons of crude oil. The effect on

the land environment was killed in huge numbers. Offers are poisoned by oil,

Ether by swallowing it as they swim through it or by trying to lick it off their

coats. However, the main cause of death is exposure too cold. If oil clogs

otters fur they freeze to death, then few of these sea attars have cleaned. But

about 3,000 along with 36,000 seabirds and over 100 eagles are estimated to have

died.

Change salt water to clean water is very easy. The scientists invent a machine

which can change the salt water to clean water. First, you have to boil the salt

water and wait until the salt water become steam then the salt will be left in

the container and wait or the steam become clean water.

Water is the most critical natural resources in the year 2,000. According to

"Thors, orig. Water spells lie itself. It's used in agriculture, domestic taps

and industry. Not only in food production, drinking and business. If we don¡¦t

protect it well, in the future it is hard to change the salt water to clean

water, then we will not have clean water to drink, to plant and to agriculture.
