Annual tolls because of sharks are much less than deaths resulted in meetings with crocodiles, tigers or elephants. 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
This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold. This allows overfishing to be a problem. Not to mention, another environmental threat that this fascinating animal, the blue crab, faces is climate change. Corresponding with the text, “Climate change is another major threat to life in the oceans. Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems,” (Digan 14).
I think Killer Whales should not be in captivity because, of the injures they can get in their tanks, how they get stressed out and they are better in the wild. The first reason why I think should not be in captivity is of what happens in their tank. The first piece of evidence from the PETA practical “Aquariums and Marine Parks” is that since the tanks for the orcas are usually small for them, they get insane because of the echolocation they use. This makes me think that since their fin sometimes curves, that they would get injured while swimming. In addition, this might make the whale die faster than what they are supposed to live to.
The Great Hammerhead Shark There are many animals in the world that are endangered. One of them is the Great hammerhead shark . These sharks have flat, T-shaped heads that make them stand out from other sharks.They are long and flat in order to aid in the catching of prey. The eyes of these sharks are wide-set. We need to protect the great hammerhead shark because it is being poached and there are only 9 Species of hammerhead shark .
Although the orca can be found in both in the open ocean and in the coastal waters, they primarily inhabit the continental shelf’s in the water less than 200 meters deep. In the cold water area is the most distribution limited by the seasonal pack ice. The killer whale is the top carnivore consumer on the food web. Killer whales may be large in size and appetite, but they still act on instinct and have no desire to kill intentionally. The killer whale is also a very playful and intelligent creature like most dolphins are, therefore they do not deserve the name killer whale.
Most people are misinformed when it comes to the Florida alligator. Alligators just like any other animal or human being want a safe and secure area of living. These creatures want to be able to live out of harm’s way. One area that seems to be protective of these intelligent reptiles is known as The Florida Everglades. The Florida Everglades is the third-largest national park out of the 48 states.
More often found on the wildlife and vegetation, especially in the tissues of fish in the rivers, thus causing serious health issues to humans eating high amounts of fish. Overall, the California Gold Rush based on history did not have many contributions and positives to the environment. The race for economic prosperity, and striking gold came at a cost with the destruction of the environment. The difficulty of extracting gold took a toll on the farmlands, hillsides, and mountains of the Sierra Nevada
Sea turtles often eat plastic bags instead of jellies. This cost for turtle a life, as plastic causes a blockage within digestive system. But this is only the beginning. Spots made of plastic cover for Sunlight cannot penetrate through plastic garbage into the water, algae and plankton, which is the bottom of the food chain, may simply die out. The situation can quickly turn into a global crisis.
Researchers of a study performed on wild and captive orangutans write, “…Factors such as improper hygienic situations, improper diet, diseases, obesity, injuries from exhibits, poor adaption to a climate, spread of infections, inbreeding, and social stress might actually increase mortality in captivity”, (De Vries 680). The study described how the modern improvements for zoo animals have only recently matched the average survival rate of wild species. Although this statement is true to some degree, it can also be argued that studies on mental characteristic are not one hundred percent accurate. Another study on assessing the mental health of captive and wild chimpanzees describes the multitude of uncontrollable variables when testing hypothesizes. The testing methods are not catered specifically to nonhuman primates and to other non-vocal species.
Predators do fulfill a valuable ecological function because they naturally monitor the population of a lower level species in the food chain. If a predator is removed from the equation, their prey can over populate. www.livescience.com/ in 2009 said that because of the decline of the Sub-Saharan African lion and leopards, their prey such as baboons have increased and becoming bold enough to even attack children. The article talks about the reason for the predators’ reduced population is due to humans either building their houses in their habitats, or from being hunted by humans.
