Over the last few decades, humans have severely affected the ocean and its ecosystem.Humans have taken advantage of the materials that the ocean provides for humans. The spread ofplastic, oil spills, and chemical waste from industrial factories and agricultural farms is veryharmful. Oil spills produce toxic waste that lodge itself in the gills of fish and feathers of birds,making it hard for birds and fish to move and breathe. Debris such as plastic, and any other typeof trash, that floats throughout the ocean doesn’t decompose for years. Because of this, thechances for survival for favorited marine animals such as turtles, sharks, penguins, and whales,decrease over time. However, not all pollution needs to takes place near or on the ocean for it toend up there. Agricultural and chemical waste dump numerous toxins in the oceans that are verydangerous for marine life. Human habits have to change in order to impact the amount of plasticpollution, oil pollution, and chemical waste pollution, and ultimately save the world’s oceans.Beginning with oil pollution, it has severely affected marine life, including disrupting thefood chain and disabling many marine species. Oil spills destroy furry or feathered animal’sability to gather food, or even defend themselves. They become stuck in the pool of oil thatsurrounds them for miles. Many marine species that get stuck in the oil can also ingest it whiletrying to clean themselves, which then poisons them. The National Oceanic and AtmosphericAdministration says, when marine life is exposed to oil, “adult fish may experience reducedgrowth, enlarged livers, changes in heart respiration rates, fin erosion, reproductive impairment,and affect the eggs and larval survival” (NOAA). With these serious conditions, it could lead to atraumatic decrease in the population of specific species of aquatic life. Causing, fish to die morequickly than reproducing, lack of natural materials humans collect for the ocean. Oil spillsgreatly affect the ocean and every living and non-living species within it. When oil entersthrough the ocean and spreads, it disrupts the food chain. It starts at the beginning of the foodchain with phytoplankton; phytoplankton are responsible for oxygenating the water that all lifeneeds to survive. If phytoplankton are poisoned by oil, those who eat the poisoned phytoplanktoncan also be harmed. Also, the animal that consumes the animal that ate the poison phytoplanktonis now poisoned, it becomes an endless cycle. People who work in the ocean with oil, don’trecognize the amount of destruction they can do to the ocean. Oil companies need to realize justhow much oil spills can harm the ocean.Plastics can take up to 500 years to decompose, so any amount of plastics humanscreate now are still going to damage the oceans for the next 500 years. Today, millions of poundsof plastic can be found in 40% of the ocean surfaces. Humans created plastic, so humans are alsoresponsible for killing marine species because of it. The article, Ocean Plastics Pollution saysthat about 12,000-24,000 fish ingest tons of plastic which causes intestinal injury. The plastic sitsin the animals stomach, and reduces the storage capacity in the stomach, causing birds or otheranimals to consume less food. By this, they are dying of starvation. Thousands of turtles, seals,and dolphins get entangled in the plastic that floats in the ocean. From being subdued bystyrofoam ropes, to swallowing plastic bags. Researches discovered that, not one square mile ofsurface ocean anywhere on earth is free of plastic pollution ( Ocean Plastics Pollution). Oftenwhat happens when birds or other marine mammals consume plastic that is often mistaken forfood. If they have live young, they feed their young that plastic, and that “food” later kills theyoung and the parent over time. Mankind has so much to thank for the ocean, but yet daily it isdestroyed by the overproduction of plastic that humans use. Only 2% of the worlds ocean ispreserved, and that’s not enough. Pollution takes a massive toll on the ocean, the life that liveswithin, and the beautiful habitats residing in the ocean.Across the world, farms are being created, and industrial factories are spreading. Theimproper disposal of chemical and agricultural waste by humans has resulted in the world’swater supply being treated like it is a toxic sewage dump. In human bodies, water accounts forup to 60%, so it’s highly important for chemicals to be disposed properly, and not end up in thewater we drink. Richard Espinoza states that, because of the improper disposing of chemicals, “two-thirds of aquatic life is considered to be endangered species because of improperly disposedchemicals and other waste” (Espinoza). When toxic waste harms one organism, it can end updisrupting an entire food chain of aquatic life. The process in which animals higher in the foodchain, such as humans, ingest these harmful toxins in extreme amounts is calledbiomagnification. Richard Espinoza observed, as we eat the fish that has the high levels oftoxins, we are exposed to having genetic mutations, diseases, and birth defects. Agriculture andchemical waste has led to a significant increases of phosphorous and nitrogen (Espinoza). Toomuch of these toxins in the ocean bring out eutrophication, which causes the excessive growth ofalgae and phytoplankton that produce negative outcomes. When algae produces too much andtoo fast at the same time, algae blooms spread. These algae blooms are known as “red algae” and”brown algae”. Both of them are responsible for killing sea birds, fish, marine mammals, andharm humans. This bloom of toxic algae creates dead zones where it is uninhabitable. Thedisposal of chemical and agricultural waste are the reasons for making parts of the oceanunlivable. Whatever waste we dispose into the ocean, later comes back into our food. If we dumpwaste into the ocean, and the fish that we eat consume this waste, these fish can directly comeback to us in our food, and poison humans.All of these factors that have deadly affects to the ocean and its ecosystem have solutions.For starters, to help prevent oil spills from happening, oil companies need to think of other wayswe can extract oil without harming what’s around us. The oil manufacturers need to inspect morefor leaks and deterioration in the equipment they use. This can help stop a spill sooner rather thanletting it pour into the ocean. However, this won’t stop all pollution in the ocean. Other reformsare needed such as plastic regulation. The simplest solution would be to stop using so muchplastic, but we need to do more than just to cut back if we want to preserve and protect ourocean. Recycling will help tremendously with less plastic caps, trash bags, and ropes that end upin the ocean. By reducing the amount of plastic in the ocean, we can make the ocean cleaner andmore sustainable for life to live. If we were to solve those pollution problems, it would only be aprecursor to environmental revolution. Along with all the other pollution problems, improperland management of farmers, and science laboratories of displaying chemical waste is one of themany factors that strain heavily on the ocean, and the marine life. The only way to stop this is toenforce strict regulations, reducing the use of carbon-oriented energy sources, and to use otheralternative water sources. Guaranteed if we follow the rules and regulations, we will be on ourway to a clean, protected ocean.Most humans aren’t aware of their actions regarding the ocean, especially those who don’tlive in coastal areas. The level of change that is required to save the ocean is, we need to stopbeing dependent so much on plastic, oil, and other materials we “need” to survive. Humans needto be more cautious of their carbon footprint. By this, we can reduce the effect of climate changeby not consuming so much energy in our homes. Limiting your use of disposable plastic, beingprecise in inspecting oil manufacturers and machines, and disposing of chemicals properly andefficiently, will keep our ocean thriving in all aspects. In order to be a healthy, clean society, weneed to give back just as much as we take away, especially if it’s from something that puts life onthis earth. Change has to happen or life on earth will come to an end sooner rather thanexpected. Humans have the ability to change the world, lets change the way we treat our ocean.As humans evolve and change over time, we have severely damaged the ocean. I stronglybelieve we have the power and the perseverance to heal our ocean. With the right tools andknowledge, we can save the life that belongs their. I’ve learned that I have directly been involvedin the destruction of the ocean. I’ve learned just how much humans impact the ocean in anegative way, way more than positively. Reading about how these animals suffer from all thepollution in their homes, and not being able to do anything, it made me realize just how much Iwant to help the ocean and preserve as much as I can. Not just animals as well, coral reefs aredying everyday, materials we need to survive are becoming extinct, and it’s not stopping. Alsowhat I’ve learned is, one person cannot save the ocean. It will take years and millions of peopleto contribute to this. People are capable of change.
