“Apparently the mass of the plastic particles is six times more than the mass of the natural plankton in the area.” This large expanse of ocean has become unhealthy for the animals that feed around the Gyre. “The plastic is found at depths of up to 30 meters. It is literally creating a landmass.” Because not all the plastic’s as it breaks down, and releases large amounts of toxic substances into the water of the Pacific Ocean. Not to mention that the Sea birds and other marine animals mistake these sand like plastics as food, and aren’t able to digest the plastics resulting in a large number of deaths of these animals. We all can contribute in helping the slow the growth of “trash Island” so some call it.
Scientists were studying this correlation and discovered some of the reasons for this higher mortality rate. Some otters are caught and killed in fishermen’s nets, some drown in lobster pots, and predators such as sharks kill some. A final explanation for their low population in California is infectious diseases, which mostly kills
B. There are patches in the ocean that are thick, like plastic soup, that have actually been given names. The largest of these has been dubbed The Great Pacific Garbage Patch and it is about the size of Texas. We throw away about 2.5million plastic bottles an hour. C. if not stopped over time the earth with slowly decay and changes in the environment will take place such as acid rain or water that’s become to toxic to drink plus animals will die from the trap like waste.
The pots were about 3 feet 6 inches and contained two to three dozen good size crayfish weighing about two several pounds. The men said it was about one hundred and fifteen to three hundred feet long. Another eyewitness saw a great white shark the size of a tractor trailer had attacked a person. Many sharks have been clocked out as fast as 1.5 miles and the mega shark could probably swim in a longer distance since this is a bigger shark. Two percent of the ocean has been overlooked by people ant it leaves ninety-eight percent of the ocean for the megladon can swim.
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.
Zach Torres Oceanography T/TH 11-15-10 Great White Shark For many years there has been one animal that has struck fear in everyone that goes into the ocean. That animal is the Great White Shark. It has been known to exceed 20 feet in length, although most are about 5 meters long and weigh somewhere between 4000 and 5000 pounds. They live in almost all coastal areas that have a water temperature that stay between about 50 and 75 degrees. Perhaps the most well known place to see great whites is Dyer Island, which is off the coast of South Africa.
These runoffs have contributed to the beach closures, and the unsustainable condition of biological life in the lake. Human health is at great risk due to the untreated waste that is dumped in Lake Huron each year. The untreated sewage contains many viruses, two being Giardia (an intestinal parasite), cryptosporidium, which causes intestinal illnesses and even death. E. coli a more familiar virus has elevated its concentrations in Lake Huron, found in either animal or human feces, which causes diarrhea, nausea, and stomach cramps. ("Testing the waters,"
In other cases, the algae blooms from eutrophication turn out to be incredibly toxic species (National Academy of Sciences 696). One particularly nasty algae is Pfiesteria piscicida which emits toxins that break down the skin of fish, causing bleeding and sores and ending in mass fish death (Howarth 39). In August 2005, a dairy farm in Western New York experienced a manure lagoon collapse, which resulted in 3 million gallons of manure funneling into the nearby Black River, where it killed as many as 250,000 fish, brought all recreation to a halt, and forced the city of
My first piece of evidence in favour of human activity leading to extinction is ‘humans are driving animals to extinction faster than they can evolve ‘written by Juliette Jowit, (on Sunday the 7th of March 2010), the guardian newspaper, 15/01/15. This source is very reliable as it has been said by experts on animal, survival and extinction. In this article it explains that humans are one of the main causes of animal extinction and this is driven by the destruction of habitats(deforestation),hunting, the spread of alien predators(invasive species),disease and climate change. Also, due to these causes humans are effecting the cycle of evolution and this partly happens through the
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. November 30, 2010).” These areas are accosted with highly populated coastal areas that are being overfished and have rich nutrient run off coming from land causing massive decline in phytoplankton. Biological Oceanographers worldwide study dead fish that continue to surface on shore by searching for a solution to the problem. Many believe the zones are created due to climate change; however, it is more logical that the constant drain off of the high nutrients is feeding the dilemma. Low oxygen levels increase stress on fish.
