This has caused the majority of sea turtles to be endangered. As you can clearly see, this has put a huge effect on sea turtle’s lives. Although many of them have been killed, they aren’t the only ones affected by this. Many other fish spices have been hit. Salmon sales have gone down because they’ve been dying.
Channa Argus, commonly known as the northern snakehead, is one of the many invasive species around the world. This species is a top level predator and was introduced to several American states in 2002, but its natural habitat is based in southern and eastern Asia. Northern snakeheads were transported to the waters of America by being sold from pet stores and live food fish markets, followed by being released into the wild. The northern snakehead fish threatens and competes for the native species’ resources and habitat. The northern snakehead preys on zooplankton, smaller fish, fish larvae, crustaceans, frogs, insects, small reptiles, and even small mammals and birds.
Sea otters have couple of normal predators in the ocean because of their vast size. Those sea otters that live further south are essentially gone after by the considerable white shark and those sea otters that occupy more northern areas of the Pacific, are gone after by executioner whales. People are one of the sea
As a result of sharks’ fins and teeth hunting, the number of these animals has significantly decreased. White sharks are often caught in large tuna nets, while hunting on them, or can also get trapped in special complex nettings that protect beaches. The English shark protection organization “Shark Trust” confirms that up to 73 million sharks are killed in targeted hunts for fins annually. Combining all the data worldwide- 200 million sharks are killed around the world each year. This is a great paradox because the number of humans killed by sharks compared to these numbers is insignificant.
The foxes are thought of to be responsible for the killing off most of the ground living animals in the last 130 years. (Red Fox) Any animal that is smaller that 5.5 kilograms is prey to the foxes, a single fox is estimated to eat about 400 grams each night. (Red Fox) Sometimes a fox will kill many animals during the night but not eat all of them, this can lead to serious food shortage for other native animals. I single fox can kill thousands of mammals, reptiles and birds every year. (Red Fox) Red Foxes are constantly is competition with other native animals on Australia, the more they eat the less food there is for the native animals.
The species was last filmed in the wild in the year 2006, in the film Life in Cold Blood by David Attenborough. The remaining species were taken into captivity as the fugal infection was rapidly depleting the zeteki population. The location for the filming was not disclosed to prevent further poaching. The other reasons for the depletion of the Panamanic frog are habit destruction due to human interference, trees cleared for housing and Urbanization , encroachment of land for agriculture, pollution and international pet trade. Even though captive population seems to thrive well thet still cannot be reintroduced into their natural habitat.
“Tilikum” SeaWorld 's largest orca, is responsible for the deaths of three trainers, which all three deaths could have been prevented if SeaWorld would have recognized the behavior change in Tilikum. The most recent death to occur was Dawn Brancheau, where Tilikum “scalped and dismembered Dawn as well as breaking bones throughout her body before drowning her.” (Prothero) Since Tilikum was the biggest orca in captivity, he need the most space which led to SeaWorld isolating Tilikum into his own tank. This may have looked like a great idea on paper but because of his isolation Tilikum was literally going psychotic. “Stress of captivity drives Tilikum to exhibit abnormal repetitive behavior, including chewing on metal gates and the concrete sides of his tank—so much so that the most of his teeth are completely worn down.” (Prothero) This stress caused Tilikum to exert aggression to other orcas when let out but also toward trainers. Because SeaWorld failed to recognize the abnormal behavior in Tilikum which ultimately led to the death of Dawn Brancheau and many
If you could save your mothers life by walking a couple yards to the nearest trash can would you? Of course you would! Dumping plastics into our oceans is a huge problem for our environment and the people that live in it. Plastics are killing our marine life. According to a Biological Diversity website (https://www.biologicaldiversity.org/campaigns/ocean_plastics/), the author states that “Thousands of seabirds and sea turtles, seals and other marine mammals are killed each year after ingesting plastic.” People keep littering and that littering is killing precious marine life.
During the late 1800s Sea Lions were hunted for their skins and meat which led to Sea Lions population to decrease dramatically then a law came out during the early 1900s to limit harvest of these animals so that they don 't become extinct. During the early years of the 1900s Japanese were killing Japanese Sea Lions for their meat to prevent starvation and used their blubber for oil to light their lamps and whiskers used for cleaning material in which their population was already low ranging from 30,000 to 50,000 then in which started leading to their endangerment and ultimately their extinction which came around the early 1950s which they presumed extinct after WWII due to the radiation the bombs gave off when the U.S dropped bombs on Japan. Going back to the sea lions ancestors it goes back to 32 million years ago and shows that Sea Lions were smaller in size like a sea otter and over those millions of years it 's gotten bigger and was close to a Walrus and was similar size but then later shrink down to the normal Sea Lion size we have today over the millions of years. Going through the Sea Lion species the steller Sea Lion during 1977 Steller Sea Lions where announced endangered due to a lot of the population suddenly disappearing to mysterious
Because they are unable to untangle themselves, they also die from starvation or from their inability to escape predators. On a report in 2006 called Plastic Debris in the World’s Oceans, It was estimated that at least 267 different animal species have suffered from entanglement and ingestion of plastic debris. Some species are consumers of jelly fish, but often mistake plastic bags for their natural prey, which obstructs the oesophagus of sea turtles therefor killing them. It has been estimated that about 400,000 marine mammals die annually due to plastic pollutions in the ocean. As said by Friedrich Nietzsche, Thus Spoke Zarathustra “One must be a sea, to receive a polluted stream without becoming impure”.
