Oceans are being polluted by substances such as farm fertilizers, chemicals produced in factories, and harmful sewage from towns and cities (Claybourne 38). Trash and debris, especially plastics, are deposited into the oceans by humans. These objects can be mistaken as food by many species, which eventually leads to death. When species consume what looks like to be food, but in reality is hazardous waste, the animal contains that chemical inside of them. When a larger animal consumes the hazardous animal, it affects the entire food chain (“What Is Ocean”).
The World Research Institute estimated that about ¾ of the worlds shallow reefs are threatened by climate change, pollution, and overfishing. All in which are man made influences that affect the ocean greatly. It is predicted that by the year 2050 90% of the coral reefs on earth will be dead or threatened. Not only that but soil erosion, algae growth from fertilizer runoff, increased UV exposure, and damage from fishing and diving are just adding to the problem. However, the
Elizabeth Miller Physical Geology Lab Environmental Issues Paper Global Warming vs Polar Bears Scientifically known as Ursus maritimus, the polar bear is a marine mammal that spends more time at sea than on land. (“Global Warming and Polar Bears”) The bears’ population is between 20,000 and 25,000 worldwide. (“Polar Bears Threatened by Global Warming, Says Bush Administration”) Stocks, or groups of polar bears, are distributed throughout the Arctic. They are known to be long-lived creatures. The ability to replace individuals is very limited and the population growth is extremely slow.
These things really are happening in the world, its called ocean pollution. Because of this marine life is constantly dying, innocent fish are mistaking plastic for food and becoming sick, and eventually all that plastic will kill everything beautiful in the ocean . Ocean pollution does not only kill marine life, but it is also is killing birds and coral reefs. Would you like
Chemicals from industries and agricultural sites can run-off into the ocean. When the toxic chemicals from this and sewage get into the ocean’s ecosystem; it leads to reduction in oxygen levels, decay of oceanic plant life, and severe decline of the quality of the sea water. Toxic chemicals that get into the ocean raise the temperature drastically, this is known as thermal pollution. Marine animals that cannot survive in these higher temperatures will eventually
Trash, Trash, Everywhere! Text By: Ashley Atkinson Edited By: Hannah Hunter and Jesse Lewis The life of your plastic water bottle can go way further than just the trash can. Our ocean is so polluted by our actions and carelessness that even us humans are being affected, sea animals, and surrounding animals are all being greatly influenced by the polluted waters. Our ocean is extremely polluted with plastics and other trash that humans have put in there. Specifically, 80% of the pollution that’s in the ocean, is because of us.
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health. Overfishing is also closely tied to by catch, another serious marine threat that causes the needless loss of billions of fish, along with marine turtles and
Examples of negative local practices are the usage of poison/explosives and overfishing. Overfishing as the name suggests, is fishing a certain fish to an excess amount, decimating the population. This could put multiple organisms’ populations at risk and populations may possibly go extinct. Another practice that negatively impacts the ocean is the usage of poison and explosives. Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years.
Thus, it is worth reiterating that unsustainable fishing is one of the biggest threats to sea animals and its continuation could possibly drive these species to near extinction. Notably, the extinction of sea animals could have a destroying effect on the food security, income, and even livelihood of many people who depend entirely on oceanic resources. Thus, humanity ought to embrace sustainable fishing practices. In addition, shark finning and whale hunting also endanger and nearly drive these marine creatures to extinction. In particular, many communities in Japan have been hunting whales for many centuries as a part of their cuisine (Huang, 2009).
Hurricanes can destroy homes and cities, even obliterating entire countries. It destroys our habitat but what does it do to affect the habitat of every other animal on earth? Hurricanes can mix saltwater with freshwater causing animals in the water to die because they aren’t adapted to living in the different type of water. Floodwater can also retreat into lakes, bringing in more toxins and killing off the remaining animals still in the water and all the animals that dare to drink the toxic water. Sediment erosion can affect coral reefs and oyster beds causing even more deaths.
