“The world produces 200 billion IB, of plastic a year which 10% ends up in the ocean.” (Kester. The world book encyclopedia volume 15.) This sharp increase in plastic entering our waters harms marine life. In the ocean, plastic debris causes damage and kills fish, seabirds and marine mammals.
Overfishing is certainly an environmental issue because it affects the planets ecosystem due to human interference. One example of this is when a marine species is exploited, other species are also affected directly. According to the article, ‘Global Consequences of Overfishing’ states that, “...recent studies suggest that overfishing of large shark species has had a ripple effect in the shark 's food chain, increasing the number of species, such as rays, that are usual prey for large sharks, which result in declining stocks of smaller fish and shellfish favored by these species” It is also important to mention that overfishing often leads to the killing of other animals unintentionally. This is called bycatching. Some marine species that are affected by bycatching are juvenile fish, bottom feeding organisms, sharks, whales, sea turtles, and birds.
Also, sewage or polluting substances that go to the ocean from rivers and different bodies of water are contributing factors. Plastics even have chemical nutrients that go to the ocean’s ecosystem. The chemical nutrients reduce the oxygen level of the ocean that affects plants, animals and ocean life. Waste is thrown directly into the ocean causing a huge
Oil can literally smother some species because it hinders their ability to absorb from the water. Plants and kelp are particularly affected by oil spills, and as the base of most ocean life it causes ripples up the food change, much like sea star wasting caused ripples down the food chain. Some species are more affected than others such as kelp, sea otters and marine birds all of which play critical roles in the marine ecosystem. Oil spills are yet another threat for these already threatened ecosystems. Unfortunately, oil spills aren’t the only additional threat, as the ocean waters
Red Tide: How it affects Marine Life Red tide in Florida is a reoccurring problem that threatens marine life every year. Red tide in Florida waterways has a negative impact on marine life because it produces toxins that are harmful to marine species. It lessens the amount of oxygen in the water which ultimately leads to the migration and death of many different marine animals. Millions of dollars are poured into red tide research and prevention every year to help predict when and where a red tide is going to form.
Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity. “ Plastic litter does not degrade, can be expected to last in the oceans for hundreds of years “ ( source 6 ).
There is an article the writer says that ''acid rains can change the composition of the rivers and the sea, making them toxic for fishes, because the quality of ozone in the thower plants of the atmosphere can causes lung to all animals". that’s shows that what people do it comes back to them in bad effects that they may kill all the animals that they need them for therapy and they may cause a diseases that ends human life . Also as we know that also the plants damaged from the pollution that they may be extinct and people cannot have a good healthy and fresh air that they maybe be sick from it and also the soil will be not good to plant in it and
Harmful fishing methods are unnecessarily killing turtles, dolphins, and destroying critical habitats. Global warming is increasing the temperature of the ocean water, reducing the generation of the base of the food web, plankton. The reducing of the plankton generation is causing major marine ecosystem change. Pollution is also a significant environmental issue HAL is facing. More oil reaches the ocean each year, a massive amount of oil has been accidently spilled from ships, which in turn is destroying animal and aquatic plant life.
It is impossible to give an accurate estimation of the amount of plastic that is being polluted into the ocean. However, in 1975 the global fishing fleet alone dumped approximately 135 400 tons of plastic fishing gear and 23 600 tons of synthetic packaging materials
Despite taking place in a space utopia for a large part of the movie, WALL-E sheds a darker undertone of consumerism, human environmental impact, and global catastrophic risk that society should take into consideration in order to prevent a total wasteland scenario. The consumerism in apocalyptic works such as WALL-E reflects that of Earth. The people in WALL-E have accumulated piles and piles of trash due to their greedy wasteful nature. There is so much waste that it even orbits around the earth itself. The people of earth today follow this same pattern as well.
