Contaminating these waters will not only harm the wildlife, but it will kill a source of food that is so dominant in Newfoundland, and also will harm hundreds of people’s jobs. Oil spills cause a lot of problems in our ocean and to our marine life. Everywhere you look people are trying to create a more sustainable ocean, and this is hard to do when there is so much pollution and threats to our environment all around us. We, as youth need to step up and try to make a change and help to make our province a better place. We can help thousands of animals survive by taking action against oil drilling in our
Algae Blooms are excessive amounts of algae that create a green, red, yellow, brown, or white film over the waters (Anderson). These colorful algae blooms are usually called “red tides” and are associated with toxic or harmful effects (Anderson). Microalgae that has chemical properties harmful to humans or other life is called Harmful Algae Blooms, or HAB’s. Over the years, there has been an increasing amount of HAB’s worldwide, in regions where they previously weren’t. (Anderson) When penguins venture out to find food for them and their family, they become covered in algae, which they later ingest when they clean their feathers.
Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
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
There are also coral reefs off the coast of Florida, USA, to the Caribbean, and down to Brazil. The Great Barrier Reef (off the coast of NE Australia) is the largest coral reef in the world. It is over 1,257 miles (2000 km) long. Types of Reefs: The different types of reefs include: Fringing reefs are reefs that form along a coastline. They grow on the continental shelf in shallow water.
They accomplish this by feeding on algae and bacteria. 8 Species of mussels are native to the river. The most prevalent are the eastern elliptio mussel and the eastern lamp-mussel. Mussels are eaten by a variety of birds, turtles, fish, muskrats and other mammals. Zebra Mussels are an invasive species that can cause harm to native species by attaching themselves to their shells preventing free movement and can even cut off their oxygen
Human Impacts on the Great Barrier Reef-Australia Introduction The Great Barrier Reef is the largest reef in the world, located in the Coral Sea off the coast of Queensland in north-east Australia the reef stretches over 2,300km. In total the reef covers over 300,000 square kilometres in area and includes over 2,900 reefs, and around 940 islands and cays. It is home to more than 1,500 species of fish, 411 types of hard coral, one-third of the world’s soft corals, 134 species of sharks and rays, six of the world’s seven species of threatened marine turtles, and more than 30 species of marine mammals, including the vulnerable dugong. Human Activities Affecting the Reef The balanced ecology of the Great Barrier Reef is one that is vulnerable to even the slightest human influence. Coral reefs require light, oxygen, clear water, special nutrients, stable temperatures and salt content to survive.
Keeping the Ocean Free of Debris Pollution in the Persian gulf is negatively impacting marine life How much are we trashing our ocean? CNN, February 12th 2015. Arabian Gulf coral reefs dying a slow death. Gulf news, June 10th, 2014. Spill, Dolphin Deaths Spark Alarm At Persian Gulf Pollution.
In the world of oceanography, dead zones are a commonly known term amongst scientists. People do not realize the effects that the zones have on the inhabitants of the ocean and the people who depend on fishing for their livelihood. This issue affects biological and chemical oceanographers, eliminating all forms of marine life due to the climate and composition change of the ocean. The continuation of this study will help scientist understand and assist in creating new ways to solve the growing problem. Areas around the world known as “Dead Zones” are being reported as “areas so low in oxygen that fish and other sea life cannot survive (Oceans Where Fish Choke.
The author also explains the important of the coral reefs to the human race. The author mentions that people ruin the ecosystem of coral reefs and millions of people depend on these fish as a major food source. Although both the essays show strong viewpoints such as the tone and the writer’s purpose, Amber Ripplinger proves to be a more effective essay because she explains more in depth about the cause and effect of coral reefs, uses detailed description, and transition and coherence are used more effectively. Both of the authors have similar tools that they use in their essays. One is the tone.
