Because of this, some shark species have dropped by 90 to 50 percent (Choi). In the 80s commercial fisheries made the population of sharks go down even further. Approximately 20 to 100 million sharks are killed each year due to fishing (lovgren). This has caused the total shark population to drop 30 to 50 percent
As of now, there is an average of sixteen shark attacks a year. If sharks were truly hunting humans, that number would be much higher than it is. Only about 4 shark attacks are fatal a year, and that number is because one bite from a shark is more than enough to kill somebody. Even a investigatory bite can be enough for a human to suffer massive blood loss, simply because a shark’s mouth size and bite force creates a devastating attack. Sharks are truly not trying to kill humans, and if they were every shark attack would be fatal.
Sharks, dolphins, turtles, seals and seabirds all get tangled in these nets, as by-catch, with no way to get out. Some of the animals that are caught die, either while they’re being dragged along the bottom of the ocean or when the fishermen bring them on deck and don’t put them back fast enough. FAO experts assessment concluded that there are roughly 27 million tonnes of global by-catch for every 77 million tonne catch. This statistic means almost 1/3 of every catch is by-catch. Fish populations are on the decline, no thanks to carless fishermen and their pollution.
They are killed as agricultural pests, and for their horns. People are trying to increase their habitats in eastern Ujung Kulon so the population can expand and grow. Black Rhinos are critically endangered because of their horns, and five to six rhinos are killed a day for food of for entertainment. Their population is fewer than five hundred. In 2016 one thousand fifty-four rhinos were reported killed in South Africa.
Loggerhead Turtle Argumentative Essay Andrew J. Thorpe English 6 Mrs. Tubergan Due 1-29-16 Did you know that one-thousand out of every ten-thousand Loggerhead Turtles will survive to adulthood. Many loggerhead turtles are being killed each year. There are many human caused threats and animal caused threats. Fishermen’s nets get broken because the turtles get caught in them and they don’t get saved unless somebody happens to stumble upon it.
Last two representatives of the huge terrestrial fauna kill around 100 people each year, while sharks have around five victims on their account. Meanwhile, tigers and elephants already had law protection, when the documentary was created, while sharks were treated as a source of valuable product (their fins) and a monster that should be killed before it would get an opportunity to attack. Numbers, mentioned by the film, created the impression the situation is totally unfair. As if officials today will forget about their efforts against the ivory black-market
They rank number one on the scale of largest predatory fish and can grow to lengths of 23 feet and up to 2,400 pounds. Despite having developed a fearsome reputation, they are less common than other shark species. Not much is known on their population size, but it is believed their numbers are decreasing because of hunting and habitat loss. Great white sharks are typically solitary creatures and only come together to mate.
However, when the whales are put into tanks they experience many more dangerous medical conditions. “Killer whales are known for their impressive dorsal fin, which in males can reach 1-1.8m tall. But, in captivity, they collapse”(Warley). In Seaworld most of the whales have collapsed fins that are turned over and are no longer straight. In the wild only one percent of dorsal fin collapse happens among whales.
Florida and California have suffered more fatal attacks with 831 total and recorded 9 fatalities in the Hawaiian Islands . In the African continent, people have suffered 586 shark attacks and 148 deaths. In South America, Brazil tops the most shark attacks with 98 and 22 killed people, since 1931. Pernambuco is the most deadliest
Common bottlenose dolphins and killer whales are the most well-known types of the dolphin on Earth. Both of them are warm-blooded marine mammals belonging to the Delphinidae family. The scientific name of the common bottlenose dolphin is Tursiops truncatus, which means “dolphinlike”, and the killer whale is Orcinus orca, which means “of the kingdom of the dead”. This name is likely a reference to killer whales’ outstanding hunting skill. In Latin, orca means "large-bellied pot or jar".
