How is the ocean helpful to humans?

Answer 1

Many Asian countries rely on fish, etc., from the sea (part of their diet) as well as other countries. If we don't stop raping our oceans of every living thing by netting and throwing back other creatures of the sea that one doesn't want (some already dead) then there will be no more food. Seafood is good for people and high in protein and use to be cheap at one time, but not so today.

Answer 2

Reefs help humans by keeping sharks away from the shores.

Coral Reefs have a large range of animals and organisms. Scientists have been researching coral and sponges, trying to find new chemicals which can replace old medicines such as antibiotics that bacteria has become immune to. Coral helps humans because they contain chemicals which help cure diseases. We must keep the coral reefs healthy or else we lose one of the most powerful medical tools. Who knows, maybe one day someone will find a cure for cancer using a chemical found in coral.

Answer 3

coral reefs, limestone formations produced by living organisms, found in shallow, tropical marine waters. In most reefs, the predominant organisms are stony http://www.answers.com/topic/coral, colonial cnidarians that secrete an exoskeleton of calcium carbonate (limestone). The accumulation of skeletal material, broken and piled up by wave action, produces a massive calcareous formation that supports the living corals and a great variety of other animal and plant life. Although corals are found both in temperate and tropical waters, reefs are formed only in a zone extending at most from 30°N to 30°S of the equator; the reef-forming corals do not grow at depths of over 100 ft (30 m) or where the water temperature falls below 72°F (22°C). Corals are not the only, and in some cases not even the major, reef-forming organisms. Calcium carbonate is also deposited by coralline algae, the protozoan http://www.answers.com/topic/foraminifer, some mollusks, echinoderms, and tube-building annelid worms. However, any reef formed by a biological community is usually called a coral reef.

Geologically, coral reefs are classified into three main types. Fringing reefs are coral platforms that are more or less continuous with the shore and exposed at low tide. Barrier reefs are separated from the shore by a wide, deep lagoon or surround a lagoon that has a central island. An atoll is a reef surrounding a lagoon that has no central island, with passages through the reef to the sea. It is generally believed that fringing reefs formed as a result of upward and outward growth of corals that became established on rocks near shore; there is disagreement about the nature of barrier reef and atoll formation. Charles Darwin postulated a progression from fringing reef to barrier reef to atoll, as a result of a slow, steady sinking of the seafloor that creates a lagoon and a simultaneous upward and outward growth of coral. Where entire volcanic islands sink, only the reef remains above water, forming an atoll. Not all scientists accept Darwin's proposal, but most current theories involve subsidence of the seafloor, although changes of the ocean level may also be involved.

Answer 4

They create a solid structure that grows upward and creates land surface eventually where people can live.

They are breeding grounds for many marine animals that are food for humans - fish, mostly.

They help clean the water in the shallow areas so it makes good recreation spots.

The corals take carbon dioxide out of the water as they grow so it reduces that greenhouse gas.

They act as breakwaters to protect beaches from damage by the surf.

Answer 5

Coral reefs are important ecosystems because many species of fish and organisms live there.They serve as Protectors and Wave Breakers.

Answer 6

Algae helps coral reefs because algae is the main food source for tiny fish, and tiny fish is the food source of other fish etc.

Answer 7

it helps human by harboring spawning fishes for future harvest..

Answer 8

the ocean is helpful to humans because they filter the water and drink it. it also contains fish and sea creatures that we can eat.

Answer 9

because they have holes on the side that so they can breath through and they are made from little baby's of coral and they land on jellyfish. the jellyfish carys

Answer 10

We travel on it, dump our waste in it, earn a living from it, get our food from it, find entertainment in it, and many more other things.
