Another thing that effects the blue crab 's ecosystem is its environmental threats. To begin, one of the environmental threats that blue crabs face is pollution. In the text, it states, “Approximately 6.4 million tons of plastic and other debris enter the oceans each year. And every year., more than 1 million marine animals die from eating or getting caught in this debris,” (Dignan 13). This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem.
There are millions of dolphins out in the oceans and they are declining fast because people couldn’t take another 12 steps to get to the trash cans that are all over the place in cities. Teens are the ones who mostly litter. Kamilo, an island in Hawaii is surrounded by thousands pieces of trash. They now call that place the Great Pacific Garbage Patch. It used to be a beautiful island but is now ruined by trash.
In recent years, Hurricane Katrina and Matthew have been very catastrophic. Katrina is considered to be the most destructive hurricane of all time. This hurricane deeply affected the city of New Orleans and the Gulf Coast. Katrina formed from remnants of a previous storm that hit the Bahamas in 2005. As conditions became favorable, it started barrelling toward the Gulf Coast.
“The hard corals were dead and covered in algae, looking like they’ve been dead for years. The soft corals were still dying and the flesh of the animals was decomposing and dripping off the reef structure” (Slezak). This isn’t the sight most people would imagine when visiting the Great Barrier Reef but it is the new normal with almost 90% of the coral in the GBR containing this look (McKirdy). Instead of the previous vibrant colors, they now contain a ghastly, white color that makes you think “Are they dead?” In a sense, they are. These corals are now considered bleached.
Japan’s Ministry of the Environment officially declared Lutra Lutra Whiteleyi or better known as the ‘Japanese River Otter’ extinct in the wild. Many searches have been conducted over the past years but the last sighting was still in 1979. The Japanese River Otter was a subspecies of the European Otter. It mostly ate shrimp and fish and could grow to be 1 meter long. It is thought the main reason for it’s extinction is due to overhunting, because it’s fur was considered very
In 2004 in Indonesia a 9.0 earthquake hit and created a tsunami that killed about 250,00 people and the author Richard Lewis recreaded the story in the killing sea because he is interested in the mysterious ocean. First on page 48 the narrator said “for as far as Ruslan could see, meulaboh had become a lake, clogged with floating debris”. this is true because meulaboh was one of the first places that the tsunami hit so all the ocean water was there and went through many cities and destroyed pretty much everything there.throughout the book Ruslan finds dead bodies and so did many of the rebels, it said that on page 49 the narrator said”across the way, ruslan can see dozens of bodies crumpled on second floor stairs of the shopping mall.” because of the tsunami, about 250,000 people had died so there would be many dead bodies everywhere and inside of every building, but especially in the shopping mall because people like to go to the mall so there would be a lot of people there. Then on page 18 the narrator said”from up top came peter exited cry.”hey, the reefs are drying up! there 's fish flopping fish around!”” in meulaboh,before the tsunami hit the reef dried up and groups of people were just standing there looking at the reef and there actually was fish flopping around, but then the tsunami hit and killed all of the tourists that were just standing there.richard Lewis accurately represented the tragedy of the tsunami in Indonesia and added a few characters that made
He compares the mass extinction of various animals 65 million years ago (Glavin, 2013, p. 167) to the depletion of big fish in the sea. This presents a false analogy fallacy (Henderson, 2013, p. 52), as the extinction of dinosaurs and near disappearance of cod have very little in common, and appears to exaggerate the situation regarding the exhausting populations of fish. Furthermore, the article later goes on to discuss sustainability in fisheries (Glavin, 2013, p. 168-169), veering off the topic of defending seal hunting. The author makes references to how the Marine Stewardship Council and their "eco-label" are forcing fisheries to take up more sustainable practices (Glavin, 2013, p. 168-169). This information appears to be encouraging the reader not to boycott seafood because the seafood is becoming more and more sustainable.
The Permian-Triassic extinction The largest of the Big Five was the end-Permian or Permian-Triassic extinction event roughly 250 million years ago, which eliminated as much as 95 percent of the planet 's species. Before this extinction, marine animals were mostly filter feeders stuck in place on the seafloor, such as crinoids or "sea lilies." Afterward, the seas became far more complex with mobile creatures such as snails, urchins and crabs. The most likely final trigger for the end-Permian was again massive volcanism, this time at the Siberian Traps, which spewed as much as 2.7 million square miles (7 million square kilometres) of lava out, an area nearly as large as Australia. Recent evidence suggests, however, that the end-Permian may have
However, the grey seal has slowly began to repopulate on Danish shores and is making a comeback. The virus that is the cause of the seal epidemic is known as the phocine distemper virus (PDV) and has appeared at least twice. This type of virus has a history of leading to masses of seals dying. In the 1950s, tens of thousands of seals died as a result of the virus. In 1988, the virus was the cause of death for over 23,000 harbour seals and 30,000 deaths in 2002.
Not only is Australia home to the Great Barrier Reef, but it is also the only continent in the world that is its own country. The Great Barrier Reef is the world 's largest coral reef system that stretches 1,250 miles off the Northeast coast of Australia. The coral reef support much of the marine life such as fish, sea turtles, and other marine mammals. In 1981, the United Nations Educational, Scientific and Cultural Organization, became in charge of the environmental protection of the Great Barrier Reef. Research found that because of the acidity in the ocean, the coral reef is at its slowest growing rate in at least 400 years.
The coral was so weak and brittle, with only a little movement of water it withered away into a fine dust of calcium carbonate shells and skeletons. The acidic water wiped out of all the coral to almost extinction. Bothered by what I saw on this trip I headed up to the boat to report my findings to the unesco. The boat ride returning to the mainland I was shocked to find out how much oxygen I used up in my tank, the coral seemed so much farther down than I expected, the sea level insinuate so much higher. Perturbed by this I knew it was all an effect from climate change and we were all to late to correct the damage we
Kissimmee River, is one of the most beautiful rivers in the world. The Kissimmee River is often compared to the Nile and the Amazon River. Surrounded with wetlands, marshes, plant vegetation, bald eagles, deer, alligators, fish, and birds. Florida was struck with hurricanes in 1926 and 1928 disturbing Florida 's ecosystem. The Hurricane in 1928 was the second deadliest hurricane in US history, causing massive flooding from the storm surge of Lake Okeechobee with over 2,400 deaths.
Another natural cause is oceans and hurricanes. Both the ocean waves and hurricanes accelerate erosion, which is a main cause to the marshes disappearing. Something New Yorkers should realize is that "80% of oil and natural gases produced in the U.S. travels through our marshes" as according to page 12. America 's economy could go so wrong if the marshes the oil processes through suddenly disappears. Also, a huge percentage of marine life loves in Louisiana 's marshes.
