There are different sources of ocean pollution, and much of it results from activities that take place on land. For example, oil is one of the major sources of ocean pollution. And some of the pollution comes from waste from cities and factories which travels to the ocean through rivers and drains. There are three different sources of ocean pollution as follows.
Fertilizers are one of the serious sources. Fertilizers runoff from farms and lawns is a huge problem for coastal areas.It wash off farms and lawn and eventually end up in the ocean. One in the ocean, they allow algae to grow. The overgrowth of algae depletes the ocean of oxygen and suffocates other marine plants, resulting in dead areas. Garbage is another type of pollution in our oceans, and it can seriously harm marine animals. One of the worst culprits is plastic. Plastic garbage,which decomposes very slowly,is often mistaken for food by marine animals. Plastic bags can block an animal’s breathing passage. Toxic chemicals also cause serious pollution problems. Run-off from manufacturing and disposal sites as well as accidental leaks continues to pollute our oceans with toxic chemicals. These chemicals accumulate in the animals that ingest them and move up the food chain. They eventually end up in the seafood that we eat. There are some mainly measures to prevent marine
In conclusion, the cause of these algal blooms is the waters that are getting warmer and the excess of nutrients in the water. It can be prevented by creating laws or by doing modifications to the animals’ habitat.
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.
Source 4: A few reasons why beach pollution is happening is because Trash and other materials that beaches rivers, bays, estuaries and oceans eventually wash up on our beaches. It includes plastic bags, bottles and cans, cigarette filters, bottle caps, and lids.Any trash that is not thrown away and is just thrown in the beach and is in the sand can eventually go into the beach and make the water dirty.A lot of people just throw the trash in the water because they do not care.Some people are too lazy to go throw it away in the trash can.

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.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
This problem may seem prevalent and it is very important to know about. It affects marine life in many ways, but humans are also greatly affected.by this problem. People don’t realize what this problem does to them. However the human race can always work and solve this issue. People shouldn’t dump trash in the ocean or any water source. Trash can destroy coral reefs and other important ecosystems and ruin marine life. Most important sewage plants shouldn’t dump raw sewage into the ocean because it provides nutrients to harmful algae. Governments around the world should put more restrictions on sewage and the disposal of it. But if the solution wants to be solved people must work together.
Research from the University of California San Diego Scripps Institution of Oceanography said that species in the ocean consume a projected 12,000 to 24,000 tons of plastic every year in the Pacific Ocean (Nall, 2014). Pollution of recyclable materials in the oceans is one of the leading causes of why some marine species are nearing extinction. Many authors of articles and books analyzing this topic tend to agree that pollution of our oceans is a problem. The future of this problem is where their ideas tend to differ. The following four literature reviews attempt to demonstrate and support my belief that pollution is getting worse in the ocean and more marine life ecosystems are being affected, but there are things that we as humans can do to change this. Imagine a world where we didn’t have to constantly worry about the vicious cycle of humans affecting animals and then animals in turn affecting us through consumption.
By the oceans being polluted not only are animals affected humans are too. What some people don't know is that they are killing of and disturbing offspring by polluting waters. "Ocean pollution results in smaller catches of fish all over the world, either by killing fish directly, preventing them from breeding, or causing birth abnormalities. Seabirds are unable to breed and whales are poisoned. Pollution also seems to be responsible for a new disease among seals. Without even swallowed, plastic can kill seabirds, turtles, and other creatures by trapping them. People drinking water from polluted seas can become sick. Deadly infectious diseases like cholera and typhoid can break out." There are many different types of sizes of plankton everywhere in our ocean waters.
This is extremely alarming to many people, because the oxygen is so low in parts of the ocean it is creating dead zones. Where animals cannot live they either relocate if they can, or they are left to suffocate and die with little to none oxygen. Another source that is harming the ocean is carbon dioxide. This gas is the same one that is in the air that we breathe today.
Different pollutants cause different things to happen to plants. Sometimes, water pollution causes an explosion of new plant growth by providing necessary nutrients and food. If there is too much of one species, this can harm or kill plants by changing their growing conditions, such as raising or lowering the environment’s acidity. Plants must take in nutrients from the surrounding environment in order to grow. Nitrogen and phosphorus, in particular, help a plant’s growth because they are important in photosynthesis. This is why they are common ingredients in plant fertilizers. When runoff from farms pollute waterways with nitrogen and fertilizers rich with phosphorus, the water enriched with nutrients often have stunts of growth. Sometimes too much growth can be harmful, as when plant-like algae bloom in polluted waters and create oxygen-depleted dead zones. One solution to this issue is planting seaweed farms in areas that get alot of runoff from farms. This is because seaweed can soak up the excess nutrients and be harvested for people to eat. Marine debris is garbage that ends up in the ocean. Plastic debris that builds up at or near the water’s surface blocks sunlight from fully reaching plants that rely on sunlight to move along the photosynthesis process. By blocking sunlight, marine debris prevent plants from creating glucose at full capacity, which stunts their growth. When chemical pollutants
When too much nitrogen and phosphorus enters into the environment it causes algae to grow faster than an ecosystem can handle. This harms the water quality, food resources, habitats, and decreases the oxygen in the water that fish and other aquatic animals need to survive. Large growths of algae blooms also lead to illness and even death. The excessive nitrogen and phosphorus that wash into bodies of water are usually caused by human activities. Animal manure, excess fertilizer applied to crops, soil erosion, sewage and septic systems are responsible for large amounts of waste, yard and pet wastes, and certain detergents that are not properly used or disposed of are some examples of human activities polluting water that eventually end up in the fish
Global warming is one of the major reasons in marine pollution. For an instance in the year 2010 there was an oil leakage near Mumbai in the Arabian Sea.
Today talking about environmental issues lately to be like a common topic discussion until people take it for granted. However, the world facing a complex environmental problems related to each trouble that connected to one another and come out with greater impacts to the environment and humans. This is because the effects of environmental only can be seen in long term period rather than immediately result show up. Environmental issues must become one of the controversial matters in the society in order to make people know the truth what the world currently facing. There were a lot of environmental disaster happened such as climate change, global warming, various of pollutions, earthquake and etc. the rise of environmental issues begin with this urban development occur through several countries following with the technologies equip along. For sure, development will cause a huge negative impact to the environment if it deals without a care. Besides, the environment is the place in the ecosystem to hold and use in finding resources to continuously survive in this world. Thus, the finding and digging for the resources which happening extensively without preservation will not restore the surrounding similar with before. But then, the change cannot be refuse and people need to take an action to save the threaten the world and the ecosystem from being extinct. If each country has own output in causing an environmental problem, then consider the world to hold all the damage occurred. Exposing the effects of environmental issues throughout the world, make people realize the important to take care the environment.
The Causes of Water Pollution Water pollution is very harmful to the environment and living things. Water pollution can come from many different sources. If the pollution comes from only one source, such as an oil spill, it is called point-source pollution. If it comes from many different sources, it is called nonpoint-source pollution. Most water pollution affects the immediate area surrounding the source, but there are some types of pollution, such as hazardous, that can affect areas miles away from the source.
