How Marine Life Is Affected By The Changes Of The Environment

How Marine Life is Affected by the Changes of the Environment Introduction Marine life is affected by the changes of the environment due to both human and natural causes. Some human causes I will discuss are pollution and the destruction of land for human uses. A natural cause I will talk about is temperature change. Temperature is expected to change naturally, but not at the rapid rate it is going now. Pollution Humans are the main polluter. We have polluted both the atmosphere and the ocean. We pollute the atmosphere by releasing vast amount of carbon through factories and cars. â€Å"Air pollution is killing 3.3 million people a year worldwide†. â€Å"the yearly death total will double to about 6.6 million a year by 2050† â€Å"In 2010, there was a total death of 54,905 due to soot and smog. 16,929 deaths out of 54,905 was due to power plants† (Borenstein). Our waste such as plastic and contaminated water makes its way to the ocean. There, it has a devastating effect on marine life. According to Lowenberg, ingestion of plastic can â€Å"result in poor health, reduced growth rates and reproductive output, or death†. A marine life that is most affected is the sea turtles. Not only are the sea turtles affected, but also their nesting sites and the baby sea turtles. Birds are also affected. â€Å"90% of birds have ingested plastics in the past 30 years† (Lowenberg). â€Å"By 2050, any bird found dead will have plastic in its stomach† (Shukman). â€Å"5.25 trillion plastic particles weighing some 269,000 tonsShow MoreRelatedMarine Ecosystem1607 Words   |  7 PagesThe earths oceans provide an enormous range of resources and affect the quality of life as we know it. The oceans cover approximately 70 percent of the surface of the earth and have a cyclical effect on weather, e.g. temperature, precipitation and air qualit y. Regardless of your views on global warming, the fact remains that humans have an impact on the marine ecosystems through waste from chemicals and debris polluting this vast renewable resource. Based upon current scientific evidence, emissionsRead MoreSea Turtles Are Not Only Affected By Pollution1030 Words   |  5 PagesSea turtles are not only affected by pollution, but they are also affected by tourist attraction. On September 5 in Costa Rica, a large group of tourists prevented sea turtles from nesting along the coastline. Due to the high volume of tourists on that day, the Ostional Wildlife Refuge was unable to prevent the disturbance from happening. The Tico Times described what happened. â€Å"Some tourists touched the turtles, others stood on top of the nests, and parents placed their children on top of the turtlesRead MoreThe Negative Human Impacts On The Oceans1104 Words   |  5 Pagesis man†. He was definitely onto something. In fact, humans have had a major negative impact on the world’s marine environment. Throughout recent human history, it has been obvious that the wellbeing of the marine environment has been in jeopardy. Pollution of the ocean, overfishing and the greenhouse gases these are all the aspects that can cause the destroying of the precious environments, such as reefs, sea-grass and coastal habitats. According to the essay and interview â€Å"Seafarming at the EndRead MoreLand Destruction By Tourist Attractions885 Words   |  4 Pagesreefs are an example of marine life endangered by this idea. Though coral reefs are beautiful to view, boats on top of the coral can destroy and hit the reefs. This is a big problem because coral reefs are home to millions of marine life. According to the book, Destroying the Oceans, â€Å"coral reefs are home to one quarter of Earth’s marine animals and plants†. With that, many habits are also destroyed. Sea turtles are not only affected by pollution, but they are also affected by tourist attraction.Read MoreAnalysis Of Seafarming At The End Of The World By Peter Meehan1096 Words   |  5 Pagesis man†.

The ocean absorbs much of this excess CO2 through air-sea gas exchange, resulting in changes in seawater chemistry. Due to human-made emissions, the CO2 content of the oceans has dramatically increased and is gradually acidifying the surface waters. As a result of human-made emissions, the amountRead MoreThe Impact Of Australian Environmental Impacts On Australia1705 Words   |  7 Pagesthe start of the environment deterioration. And since the environmental issues are directly related to population growth, human activities and associated developments, it is definite that Australia will still be encountering future environmental challenges. Even with the compliance to legislation acts and protection policies, Australia is at the forefront of environmental management but in fact were are leaving our future generations major environmental problems such as climate change, fresh water allocationRead MoreThe Effect of Melting Glaciers896 Words   |  4 Pageschanging of our climate in recent years has been on our glaciers. These massive sources of fresh water can greatly change our ocean climate, which can lead to many negative effects on the marine environment. The ecosystems within this environment rely on a delicate balance, and glacial melting can seriously upset this equilibrium. One example of how glacial melting affects marine life is acidification. Each year the ocean absorbs about two thirds of human output of CO2, which is sent into the deepRead MoreA Brief Explanation On The Importance Of Clean Water1170 Words   |  5 Pagespaper a brief explanation on the importance of clean water is illustrated. Proceeding with descriptions of water pollution and reasoning’s demonstrating why it is presently a common issue in the United States. Understanding how the quality of the environment becomes affected from poor water quality is imperative to know and is proven throughout the paper. The paper slightly touches on the growth of human population and technology advancement, which are two main factors that contribute to the increaseRead MoreThe Impacts Of Climate Change1534 Words   |  7 PagesThe impacts of climate change In the twenty-first century, climate change has proved to be a major disaster affecting every country across the world. The adverse effects of the climatic change will continue to influence the next generation if adequate measures are not implemented (George 86). Climate change is a controversial topic. Scientific evidence shows clearly that future generation is at risk though the government and the public responses to this threat are moderately weak. Several corporations
