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
2. Do background research – Utilizing at least one scholarly source, describe how variations in dissolved oxygen content in a body of water can affect fish populations. Answer = “Oxygen depletions are the most common cause of fish kills in ponds. (Aquaplant, 2014).” Based on my observation of the chart and what I read, the higher the dissolved oxygen levels the number of fish drops. Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases.
Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
Mangroves I. Paraphrase Surviving is a mangrove’s expertise. Compared to trees, they exist as floating islands, living and going wherever the wind takes them. There are all kinds of mangroves, especially in the Galapagos and Florida, always getting butted by sharks. Disasters such as a hurricane cause them to become the floating islands described.
Biodiversity may also be reduced if invasive species, such as the zebra mussel or golden algae, are introduced into a waterbody during the drilling process. During the drilling process, wells for drinking water may become polluted with a variety of contaminants, such as methane gas. Here I have a video showing exactly what the drilling is doing to peoples water supply. Gas wells require miles of roads and pipelines to move the natural gas from the drilling site to the market. Construction of these transportation corridors can break up the natural landscape and impact wildlife habitat.
It describes how the Bluefin is viewed in many different lights either as food or an economic goldmine to those that fish them, legally or illegally and how powerless the authorities are to stopping the underground trade. They then present the idea that there is only way to preserving the species; by commercial fish farming in protected waters. Overfishing and Fisheries Management: Stocks of commercially fished species must be managed carefully to ensure that the catch (take) does not undermine the sustainability of the fishery. In Australia, about 50 species make up 85% of the commercial catch. The most important species are either fully exploited and are being managed to achieve a sustainable yield, or have been overexploited and are now being managed to allow recovery.
This complex ecosystem is both an extraordinary geological and ecological feature of Florida and encompasses a historic, social, economic, and environmental significance. The IRL is a network of people, places, and natural resources that are inter-dependent upon each other. Unfortunately, the primary threat to this unique ecosystem comes from human population growth as well as coast-line developers. The storm water and sewage run-offs pose significant pollution problems to the ecosystems survival. Today, scientists, and resource managers are concerned about the future of the lagoon, including declines in quality of the water, loss of habitat, biological diversity, invasive species, diminishing fisheries, and the declining of the ecosystem’s health.

“Cod is so beautiful, the way the flesh unfolds in white leaves” -Alain Senderens Our world today is the result of major events that happened in the past, contributed to by a variety of factors. One important yet unusual aspect of American history is cod, the factor that had initiated much controversy. At the beginning of American history, cod had been referred to as “the sacred cod,” the fish whose history is relevant to European discovery of North America, development of slavery and technology. Mark Kurlansky, author of Cod: A Biography of the Fish That Changed the World, emphasizes the effects of cod on the Western Hemisphere and how cod has promoted European travel and exploration into America. Due to its excellent adaptation and its nutritious content, cod is a remarkable catch with every part of its being a useful resource.
Some immediate impacts consist of oil coated bird feathers causing birds to lose their buoyancy and the ability to regulate body temperature. Mammals could have ingested oil which causes ulcers and internal bleeding. Sea turtles were covered in oil and dead and dying deep sea corals were discovered seven miles from the Deepwater Horizon well. Amore long term but serious effect is that the BP oil spill hit at the peak of breeding season for many species
