Transcript of Marine Ecosystem

Marine Ecosystem Locations Human Impacts of the Marine Ecosystem The Marine Ecosystem Global Changes Where has there been an interruption in the food web? Within the marine food web, not all the parts of it are included. One of the major ones are the commercial fisheries which produce large amounts of fish everyday for consumers to buy. Another feature would be the large range of different species of fish within the ocean, some fish feeding on specific species. Some features which could affect the marine life could be rubbish, oil spills and maybe even pollution in the water. Rubbish can float across the world and can end up from Australia to America, therefore there is a chance where fish populations in America could become affected, so it is a global situation. How have Zoos and Organisations helped? At the moment many different conversation organisations from around the globe are trying to do their bit in helping preserve the marine life. One example of these organisations would be the Antarctic and Southern Ocean Coalition (ASOC) are currently working towards stopping illegal Southern Ocean fisheries from destroying the toothfish stocks, the most important commercial fish in the region. Unfortunately there are also long-liner fisheries that kill the endangered Albatross and other species. These are non-profit organisations that are only dedicated to helping the conservation of the ocean through the use of science and education. Human life has relied on the oceans are the world for food, waste dumping and for economic purposes as well. Human impact on the ocean has increased due to the large populations living close to the coast, although not all actions at the sea affect it, actions on land can also play a part of the ecosystem. With the advancing technology in fisheries around the world, the stocks of fish have greatly reduced over time leaving species of large fish hungry. Due to the overfishing in some areas, the people have decided to limit fishing in some areas, to increase the survival of large species of fish. The Marine Food Web How can Zoos further help the situation? In my opinion, Zoos can be very helpful in what they do. With their resources and supplies endangered species and animals can be protected. Some people think that Zoos only want to raise money, they are wrong, Zoos are run by people passionate enough to care for animals using their own time. Although the current conservation organisations are doing a great job, there are still many ways they could improve. As a non-profitable organisation, their job isn't to raise money, but to be able to contribute to the company in different ways. A good idea I have is that the Governments around the world should have a law which protects the marine life, by limiting the amount of fish they gather everyday. = Marine Ecosystems At the moment there are currently 62 different types of areas in the world which show large species of Marine life. Most of these locations are close to the coast of countries and islands. Since the marine life and homes are close to civilisation, due to this pollution from large ships can be a factor in damaging underwater homes for many species of fish.
