Due to sea level rising coral reefs are getting destroyed, as they cannot survive in water above 25m. Also the increase of sea levels changes the nutrient flow, which will further damage the food chains. Furthermore coral bleaching is another side affect of global warming which affects the coral reef. Coral bleaching is permanent damage and is effected globally. It gets especially worse during an El Nino year.
Brevetoxin (also known as red tide) is a problem for not only marine life, but us humans as well. As stated in the first altered oceans video, one of the major problems with the ocean is that it has turned into a bartering field where we deposit our trash and “shop” for food by pulling fish out of their habitat. What if even our fish and trash weren’t the only problem? Well they aren’t. Researchers and even residents around Florida’s sunny coast have been discovering the red tide’s harmful effects on marine life.
What Fishing Method is the Most Detrimental to the Survival of Coral Reefs? Extended Research Essay 5/16/2013 ROSS FERGUSON [Word Count: 2929] 1. Abstract The global demand for fresh fish to eat, and for live fish in the aquarium trade has resulted in heightened frenzy to catch fish at all costs, some resorting to illegal methods to accomplish this task. This essay is discussing and finding out What Fishing Method is the Most Detrimental to the Survival of Coral Reefs. This only includes the four illegal fishing methods I have chosen to research bout and what their impact is.
Plastic disposal in our oceans is becoming a fast problem that needs to be addressed by every individual on the planet. Plastic in the ocean is a devastating epidemic that is threatening our planet with every plastic bottle that to make its way to the recycle bins, becoming a problem for marine animals, humans, and is an issue that we can easily help. Seabirds, sea turtles, fish, and marine mammals often feed on plastic debris that they mistake for food. Ingesting this plastic kills marine mammals. Whales and sea turtles often mistake plastic bags for squid, and birds often mistake plastic pellets for fish eggs.
Fertilisers, sewage and pollutants can have direct impact on the coral reefs. They grow algae a lot which ends up covering the ocean and sunlight cannot reach the coral reef for growth. Since the coral reefs are near rainforests, when trees are logged, the ground will break apart into the sea from hard rain which damages the coral reef. Oil Spills Many routes for transporting oil is in the coral
Costal ecosystems can be severely damaged or completely destroyed by raw sewage from urban settlements, agricultural chemicals and increased sediment from land disturbance. For example, in tropical areas coral reefs are at risk due to a variety of human activities and their consequences such as tourism. Also, mangrove forests are vulnerable because of the development of prawn
Africa and Florida’s environment both have issues and damages. The damages of the environment affect the animals that live in the area. Florida is known for its pollution in certain areas and this is what hurts the animals, from ranches and farms polluting the watered area where animals live they die off because of what is thrown in the water. In 1990, Florida Legislature banned drilling. This drilling happened on the coast-line with this happening most drilling comes with oil and with oil in the way of an animal they’ll get covered in it and soon die.
Birds are a very important part of the national food web (Sayre 16). Pollution is very affective on wildlife. When sewage causes huge growths of algae, it uses of the oxygen in the water, ultimately killing the wild plants and fish that live there (Barton 7). Poverty and overpopulation are also huge threats to wildlife (Barton 20). Habitat alteration is the main factor in species endangerment throughout the world (Plant).The main reason birds are endangered is because of habitat loss.
Another item pointed to pesticides, fertilizers and road salt as additional contributors to the pollution problem. And even further a New York Times article spoke about the algae blooms resulting from phosphate pollution. The lake has experienced a decline in its fish production attributed to the “dead zone” resulting from algae blooms. Further, the fish caught have ingested plastic and plastic the article argues attracts chemicals like bisphenol A (BPA) a contaminant said to affect the endocrine system. This
The oceans salt water would mix with freshwater and CO2 would get absorbed into the oceans causing disabling effects on our waters food chain. There may be oxygen poor zones in the ocean, coral extinction, and a decline in photoplankton (Skeptical Science, 2012). Our natural water springs may fail causing people in different areas of the globe to live without drinking water. There could be more wildfires, droughts that cause a loss of vegetation, and heat deaths or floods and storms (Enzler, 2007). The migration pattern of birds and other animals will change, there will be a disruption in our foodchain on land, and the possibility of loosing some species.
