The Importance of Our Seas and Oceans

The Importance of Our Seas and Oceans
The seas and oceans take up over 70% of our world but we don?t think it as important as land /air. We use it as an extended motorway, which we can pollute and sail across without a care; there are many interesting facts about the seas and oceans that most people didn?t know, "sunlight can only penetrate 100 meters freely. Only about 5% of sunlight penetrates to a depth of 80 meters." And "the deepest place is near the Mariana Islands in the Pacific. The water is over 36,000 feet deep in the Mariana Trench." (Over 7 miles deep!) I had no idea about this and, neither had most of my friends! We all know that the ocean is important but many of us do not realise how important it actually is, the main problem is whether we as a country should be telling other countries how they should look after the ocean, because we are not in their position. We do not realise how much we rely on the ocean until something goes wrong with it. Researchers do not know as much about the oceans as they do about land and I believe that this is something that we should be concerned about as the ocean has been in existence much longer than we have, and all species originally came from the seas/ oceans.
There are many dangers to the oceans by pollution. The major sorts of likely pollution are: Sewage (human waste, run off from roads, domestic cleaning produce, industrial effluent and much more), Nutrients (essentialfor the growth of phytoplankton- [extremely small plants] and act as a sort of fertiliser, however too much of this can damage the environment.), Oil (much comes from land-based sources i.e. flushing of ships? bilge tanks at sea. This can be devastating to wildlife, and sadly clean-up operations are rarely completely successful.), Industrial waste, Litter (Fish, Seabirds, etc. can easily become entangled in plastic rings, plastic strapping and nylon ropes. Many suffer a long and painful death just by discarded rubbish. ) and Radioactivity ("There is a concern expressed about the disposal of drummed radioactive waste into the sea and are fears that radioactive substances would harm marine food chains.") We are affecting the ocean by the large quantity of life we take from it. People make a meal of tuna; crab, cod, haddock, halibut etc. yet do not even let the fish have a chance to live. I?m not saying that we should all suddenly become vegetarian overnight, in fact I?m one of the worst offenders of fish eaters that I know, but have you ever wondered where they came from and what damage you are doing to their environment? The species that live in the sea should be entitled to life just as much as we should. In fact more, I believe, as they have been here for millions of years before we had even started to evolve. I believe that commercial fishing damages the seas tremendously as they do not have time to reproduce and soon different types of fish will be endangered and our oceans will be empty, they also catch whales/ dolphins in these type of nets which is why a large percent of them are now extinct. Commercial fishing only benefits the companies and many beautiful sea creatures such as whales and dolphins can become tangled in the nets and can die. At the moment, some species face the likelihood of extinction during our lifetimes and we need to do all we can to make sure they do not become extinct like so many other species. There are many of different species in the oceans such as: "Sponges, Mollusks, Crustaceans, Cnidarians, Sowerby?s Beaked Whale, bottle-nosed dolphins, Grey Whales, Atlantic Hagfish, Atlantic Salmon, Basking Shark, halibut" etc. which could all become extinct without our help. Many coral reefs around the world are declining as a result of marine pollution, overexploitation of the reef?s living resources, and physical destruction of reefs and associated coastal forests and sea grass meadows. Also, as coral reefs seem to be predominantly sensitive to little increases in temperature, global warming may threaten the livelihood of the coral reefs. I believe that companies? gain is not as important as helping one of the largest habitats stay alive and I believe we should do all we can to help. Some people say that the environmental laws are not strict enough, sadly I do not know what they are, but as far as I can see, if draggers are still being pulled across our ocean floors then I could say that the government needs to take this seriously. I know, the government is trying to stop air and land pollution, but until I had done some research for this piece, I had no idea how much we pollute and abuse our seas. They should be made to understand that: "Once we have lost the oceans we will never be able to get them back"
