Dr Carl Meyer from Hawaii Institute of Marine Biology stated that mass levels of shark culling “runs the risk of ecosystem-level cascade effects where a general lack of sharks results in boom or bust in populations of species further down the food chain”. Furthermore when nets are used to trap sharks, often animals such as dolphins, turtles, whales and dugongs become trapped in them. Turtles are one of the most endangered species as a whole and are just innocent bystanders in this war between humans and sharks. We need to be careful of not affecting other animals in this quest to reduce shark numbers in the name of nothing. Sharks can already be caught legally by commercial and recreational fishers so any cull would be largely
These fish pose a significant threat to the great lakes due to their large size and feeding habits. The bighead carp consume vast amounts of food and quickly dominate a water body. The Asian Carp were imported around the nineteen seventies and were used for aquaculture operations. Although some believe that the Asian Carp should be kept alive because they are rich in omega-3s and are now being served in restaurants, Asian carp should be removed or eliminated completely from the great lakes because they will decimate the billion dollar fishing industry in the Great Lakes, and permanently damage the ecosystem. Some believe that the Asian Carp should be kept alive because of their nutritional value and their recent emergence in restaurants.
Litter sizes vary from one to 15 with White Tips are a commercially important animal to humans seeing as how its fins are used for shark fin soup and its meat and oils utilized for consumption, its hides are often used for leather as well. Many scientists have referred to this shark as the most dangerous shark in the world, despite the more notorious Great White and Tiger, the white tip is responsible for more human deaths then all shark species combined. With one incident alone, the torpedoing of USS Indianapolis on 30 July 1945, giving a minimum figure of between 60 and 80 sailors killed by sharks. While diving with these sharks is done often it is not advised. So Respect and Fear this great animal who is number 4 on animal planets deadliest
c. In the 1930s, beluga whales had been killed along the St. Lawrence River by fishermen because they thought whales destroy the fishing industry. d. Arctic natives still have hunted belugas for food and other raw materials. It is important for their culture, but they have been killing belugas too much about 200 to 550 in Alaska and about 1,000 in Canada. 3. Environmental Hazards a.
Many different kinds of fish live in the reefs as their haven for feeding, reproduction, and safety from predators. Without an ecosystem to live in, these fish species will become extinct. Ten percent of the world's reefs have been completely destroyed. Coral reef destruction is the worst, over 70% have been destroyed and only 5% can be said to be in good condition. What has happened to destroy so many reefs?
The beef noodle that my friend cooked was nowhere near the pho that a lot of Americans can enjoy. It was bun bo Hue which was a very spicy kind noodle that we were also very proud of but cannot introduce much to the world because it had much of shrimp sauce in it. When you put shrimp sauce into the pot of boiling broth, the vaporizing steam brings out the smell of the sauce so strongly and fiercely that when you invite friends for home cooked bun bo Hue, you don’t have to give them the address, just tell them the street name and they will find your house correctly. My foxy friend put a very generous amount of shrimp sauce into his cunning plan and his poor next door neighbor raised up a sign of home for sale in no longer than a few month
There are five main things that affect the ocean and harm it, Whaling, overfishing, factory fishing, global warming, and pollution. Every year the Japanese government kills mink whales. They kill at least eight hundred fifty of these whales. Factory fishing is also a major harm to the ocean. Factories create equipment that destroys species in the ocean.
Drowning in Plastic It’s hard to imagine life without plastic. It’s everywhere: covering our food, holding our purchases, protecting our loved ones, saving patients in hospitals and floating along our waterways and oceans. The thought of living in a world surrounded by toxic chemicals and pollution is a thought which many would rather not think about. Plastics have revolutionised the world in which we live, but with dire consequences. The production of these toxic-filled substances continues to lead the human race on a path of natural destruction; with thousands of animal sea-life dying annually from plastic consumption.
Some of these transplanted organisms spread rapidly, decimating populations of native species. Zebra mussels, for example, were introduced to the Great Lakes via the release of ballast water from ships coming into port. They have now spread to the Hudson River, and are out-competing native clams. Invasive or alien species are now drawing attention as an important vehicle of extinction. At one time, as many as 500 species of cichlids existed making Lake Victoria one of the most diverse lakes in the world.
Conclusion Introduction Everyday thousands of marine animals were being cruelly killed in many parts of the world. Most of them were for money. It grew worse after egg collection became legal in 1987.Many species of sea animals are in the verge of extinction. It includes whales, turtles and many kinds of fishes. Latest technological advances have increased the threat to the marine animal, especially for turtles.
