The tremendous impact that oceans have on our planet engender how we live our lives on this earth. In this respect, we can agree that our lives depend on oceans and their many contributions to the earths environmental services. The oceans are a part of what make our planet different from any other planet in the solar system. Incidentally, oceans take up more than two thirds of the total world; other than giving us a form of outdoor recreation many people seek out the ecosystem services by visiting the beach it is a place where people utilize the invaluable aesthetic and spiritual value of the ocean. Some travel beneath the surface to have fun and explore its beautiful habitats. The ocean is an immense structure that sustains life on earth .
As such, without the oceans we would not be able to breathe due to fact that various organisms that live in the oceanic environment such as phytoplankton and stromatolites which create oxygen and help us to stay alive and allow .Aquaculture plays an important part in the ocean's services by bringing within the realm of possibility a new way of food production around the world by making sustainable long- term practices available, and food security as well as environmental costs being leveled.
Furthermore, when it comes to the worlds food source, we rely on the ocean for ''$21 trillion in food'' , due to fisherman fishing frequently for people's meals and as a means of income. Seafood being a dominant food source in the human race because of its nutritional and abundance of omega 3, protein and other mineral substances that are beneficial to maintain health, therefore, bestows the ocean's additional services upon us. In addition, to many of the animals that live among us they a...

Although it is remarkable that these marine mammals are capable of so much, there are things the public does not know. According to classified statistics, twenty-three out of forty-three animals died while being transported from their natural habitat to foreign aquariums for training. Another thing the public does not know is in reference to a similar marine mammal program in the Soviet Union. It has been reported that Soviet dolphins were trained to do "kamikaze" missions. Explosives were supposedly strapped to their backs and they were sent out to destroy enemy submarines. According to statistics, about two thousand dolphins have died on these, and similar, missions.

Earth's oceans make up over 75% of the Earth as a whole. With that being said, it is vital to understand the significance on the contents of the oceans. Since fish and marine products make up a large portion of our diet, fishing practices need to be properly managed. In this essay, overfishing will be defined, its consequences will be revealed, and plans for proper fish distribution will be executed.
The ocean is inhabited by many and loved by all. Whether you surf the waves or use it for recreational purposes, its important to us all. There are dangers to the ocean that anyone who bathes in it should be aware of. Besides the obvious dangers of the current and the pounding waves, there are possible microscopic enemies at large. Every year the beaches are closed for a variety of reasons. Sometimes it may be for a surfing contest, or if the waves are too dangerous, but the most overlooked may be ocean contaminants. Around 20% of ocean water pollution occurs naturally. Its important for the public to aware of the contaminants that reach our waters and how they get there.
Countries, fisheries, and consumers all need to share the responsibility for conserving endangered marine life. First, governments should base their policies on scientific factors and should look for better economic incentives to stop fisheries from overfishing. Second, fisheries should use methods that are not so destructive to the fish population. Finally, consumers should avoid buying endangered seafood, even if they have to pay a little more. If these parties recognize that it is worthwhile to conserve marine species, then they must accept this responsibility.
One of the sectors facing the largest impact is the seafood industry. Fish products are prevalent in pet food products as well as human diets. Given such a high demand on the seafood industry,
Oil is a non- renewable fuel because it takes a very long time to form
Sharks are the apex predators of the ocean, meaning they regulate the marine food web. The ocean (there is only one, not 7) covers between 70 – 75% of the earth’s surface and houses 80 – 90% of all life on earth, yet sharks role in maintaining the ocean is often overlooked. The main reas...
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship
Ocean Pollution is a serious issue in today's global politics. The delicate balance of Earth's ecosystem is put in jeopardy when the ocean is not clean. Problem evolving from ocean pollution directly harm marine life and indirectly affect human health and the Earth's many valuable resources. Ocean Pollution is a Broad term that encpompasses any and all foregin matter that directly or indirectly makes its way into the ocean. This includes everything from the extreme: oil spills, Toxic Waste dumping and industrial dumping-- to the small scael: human activities and basic carelessness. Because the oceans and all other water bodies are invariably, somehow connected, and because they account for 3/4 of the Earth's surface, they are an ideal method of transportation for pollution, allowing the rapid spread of seemingly far away toxins into a river near you! It is increasingly important that we educate ourselves as to what, exactly, ocean pollution is, so that we can identify the causes at their source and take action in small and large ways, and hopefully, prevent this terrible form of pollution from getting any worse than it is today.
Water pollution has had devastating effects on the environment, which include irreversible effects on the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousands of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever unless there is a balance. We must protect the resources we have in order for them to last into the next generation.
While a beautiful sunset on the beach can be astounding, a spectacular scene is not the only benefit oceans provide. Without the oceans, we would not have adequate amounts of oxygen to breathe or enough protein to eat. The Earth's climate would not be inhabitable for human beings and many animals. The oceans supply medicines, food and drinking water which arise from ocean processes. Out of the five oceans, the Pacific Ocean is the world’s largest and deepest ocean. It spreads over an area of 165.2 million square kilometers. More than 25,000 islands float within the Pacific. Within the Pacific Ocean lies an unusual island, an island that is more than twice the size of Texas and is earth’s largest landfill, the Great Pacific Garbage Patch (McLendon). Society is unaware that the excess use of plastic and other non-biodegradable materials has ended up in the middle of the Pacific Ocean and is the main source of ocean pollution. The solutions, ranging from manual clean-up to eliminating any further obliteration to the Garbage Patch, will reduce the amount of effluence the world has to endure.
