“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. Marine plastic pollution has impacted at least 267 species worldwide, including 86% of all sea turtle species, 44% of all seabird species and 43% of all marine mammal species.
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.
This tells us that the main cause of plastic waste in the ocean is the inability of common people to dispose of their waste properly. 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
This is caused by currents pushing all the debris out to see from, rivers, streams, harbors, storm drains, etc. This pollution belt causes many problems for the ecosystems is comes across with. Fish can eat the garbage or get trapped in something from the trash causing death in most cases. Let
It also is toxic to many aquatic species during various parts of their life cycles. 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.
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. All the while, millions of dollars are being lost due to a drop in tourism and bans on fishing as red tide wreaks havoc on businesses and marine life.
Marine life habitats are getting destroyed, marine life is declining everyday, how and where the garbage is getting into the oceans, and the drinking water is becoming seriously unsafe to drink. 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.
In a website Causes and effects of environmental pollution- conserves energy future.(2009). 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
Overfishing is serious problem in the world today, more than half of the world’s population depends on the oceans for their primary source of food. 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.
It is also ruining the amazing marine biodiversity that South Africa has. Pollution not only comes from industrial sector such as oil companies, but also from littering and sewage. Plastic pollution is one of the types of pollution that effect the marine environment. 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
