                        The ocean could be a continuous body of saltwater that covers over seventy % of the layer. Ocean currents govern the world's weather and churn a plaything of life. Humans rely on these swarming waters for comfort and survival, however, warming and overfishing threaten Earth's largest environment.

The oceans hold concerning 321 million three-dimensional miles (1.34 billion three-dimensional kilometers) of water, which is roughly ninety-seven % of Earth's water. Seawater's weight is concerning three.5 % dissolved salt; oceans are made in element, magnesium, and metal. The oceans absorb the sun's heat, transferring it to the atmosphere and distributing it around the world. This transporter of warmth drives international weather patterns and helps regulate temperatures toward land, acting as a heater within the winter associate degreed and air conditioning within the summer.

The oceans square measure home to voluminous Earth's plants and animals—from small noncellular organisms to the large baleen whale, the planet's largest living animal. Fish, octopuses, squid, eels, dolphins, and whales swim the open waters whereas crabs, octopuses, starfish, oysters, and snails crawl and hotfoot|rush along with |cannonball along with |bucket along|belt along} along the ocean floor.
ocean environment:
Life within the ocean depends on flora, largely microscopic organisms that float at the surface and, through chemical process, turn out concerning half the world's atomic number 8. alternative fodder for ocean dwellers includes alga and brown algae, that square measure styles of protoctist, and seagrasses, that grow in shallower areas wherever they will catch daylight.


     ocean environment:

Human activities have an effect on nearly all elements of the ocean. Lost and discarded fishing nets still lethally snare fish, seabirds, and marine mammals as they drift. Ships spill oil and garbage; they additionally transport critters to alien habitats unprepared for his or her arrival, turning them into invasive species. angiospermous tree forests square measure cleared for homes and business. Our garbage—particularly plastic—chokes the seas, making Brobdingnagian "garbage patches" like the good Pacific Garbage Patch. fertilizer runoff from farms turns Brobdingnagian swaths of the ocean into dead zones, together with a replacement Jersey-size space within the Gulf of Mexico.
ocean environment:
Climate amendment, the term scientists currently use to explain warming and alternative trends presently poignant the world thanks to high greenhouse gas emissions from humans, is strikingly mirrored within the oceans. The year 2018 marked the oceans’ hottest year on record, and hotter waters cause a variety of consequences, from dynamic colors to rising ocean levels to additional frequent powerful storms. The gas greenhouse gas is additionally turning ocean waters acidic, associate degreed an inflow of fresh from melting glaciers threatens to change the weather-driving currents: the Atlantic Ocean's currents have slowed by concerning fifteen % over the past few decades.
ocean environment:
A community of scientists, explorers, and national scientists continues to check the ocean, hoping that additional data can yield additional methods for conservation. Underwater drones, as an example, a square measure being deployed to explore subsurface frontiers, whereas new tools live} serving to scientists measure and perceive what they realize. scan additional concerning ocean threats and solutions here.



ocean environment:
The ocean is that the birthplace of life on earth. Over many billions of years, it's developed into what it's nowadays through an awfully Byzantine and complicated balance of natural phenomena. The ocean remains home to many hundred thousand completely different plant and animal species. it's essential to all or any living beings, each within the water and toward land. The oceans give the foremost basic wants like the atomic number 8 we'd like to breathe and far from the food we tend to eat. additional recently, the ocean has been discovered to supply delivery medicines that fight cancer and numberless alternative ailments.
ocean environment:
Additionally, feckless actions taken by the exploding human population has caused the whole extinction of many hundred plant and animal species throughout the previous few hundred years. per data revealed by the globe Conservation Union (IUCN) together with over 600 scientists, twenty-fifth of vertebrate and amphibian species, Martinmas of birds, two hundredth of reptiles, and thirty-fourth of fish species surveyed to this point, square measure vulnerable with extinction. additionally, another 5-14% of species in these teams square measure "nearing threatened" standing.
ocean environment:
Today, some scientists believe that we tend to is also losing over thirty,000 plant and animal species a year. This rate is far quicker than at any time since the last nice natural extinction sixty-five million years past that killed most of the dinosaurs. Seven out of ten biologists believe the globe is currently within the interior of the quickest mass extinction of living things within the four.5 billion-year history of the world per a poll conducted by the Yankee repository of explanation and also the Joe Louis Harris survey analysis firm. This loss of plant and animal species will lead to the loss of any potential edges these species could have provided to the United States. the chances embrace discovering new medicines and potential cures to human ailments. concerning twenty-fifth of medicine prescribed within the U.S. embrace chemical compounds derived from wild organisms. Billions of individuals worldwide have confidence plant- and animal-based ancient medication for his or her primary health care.
ocean environment:
In 1998 at the beginning of the international organization International Year of the Ocean, over one,600 marine scientists associate degreed conservation biologists from sixty-five countries issued an unprecedented warning to the world's governments and voters that the ocean is in hassle. The agreement is that destruction of marine biological diversity stems from 5 primary causes:
