Wolves should be kept on the endangered species list because as seen through evidence they help the environment in many ways that people don’t always see. Imagine a world where wolves don’t keep the deer numbers in check or kill off diseased/injured animals, the whole ecosystems of some areas would be completely ruined. Other animal species would die out if wolves are their main predator because they would begin to over populate which would leave them to over using their food supplies and then starving to death. Animals would have to be forced onto the endangered species list costing us tons of money only for it not to really help. It would be sort of like a chain reaction if wolves were to be taken of the list and then go extinct, and we never know if that chain reaction would affect us very badly or if it not affect us at all until it is to
One of the main reasons polar bears are going extinct is because they aren’t getting the right amount of food they need to survive. Seals, the main food source for the polar bears, are animals that depend largely on the algae that grows on the ice of the Arctic. With the ice content slowly depleting, there isn’t enough seals to sustain the polar bear population. One of the
Sadly, many Americans believe that losing the wolves would not be a bad thing for the prey’s sake, but in all reality losing the wolves would be devastating. One major thing that is present in all ecosystems, the place in which animals live, is a trophic cascade. A trophic cascade is explained in the essay as a “sequence of impacts down the food chain” (578). Hannibal gives the reader this example: “…In Wyoming’s Yellowstone National Park … wolves were virtually wiped out in the 1920’s and reintroduced in the ‘90s. Since the wolves have come back, scientists have noted an unexpected improvement in many of the park’s degraded stream areas”
Poaching and illegal hunting can cause an off set in the ecosystem by overhunting animals. When one animal population decline drastically, other organisms are affected too. The decline in native predators is the main cause for overpopulation of animals like deer. Deer overpopulation has led to rapid decrease vegetation life causing other animals to be put at risk. Removing predators from the food web disrupts the entire balance of an
As each day passes by, he becomes disturbed as he’s trapped in a small enclosure with no peace. Other animals at the zoo also show signs of stereotypic behavior, Arctic foxes pace back and forth and scratch at the walls aggressively as if they are trying to attack something or someone. The staff members and the owner of the zoo does not care for the well-being of the animals at the zoo instead all they care about is making profit. In Argentina, a zoo called the Mendoza Zoo, is home to the “world’s saddest polar bear”- Arturo the polar bear suffers from depression and stress as he lives in captivity. When the temperature is too hot for Arturo to live comfortably in his enclosure, staff members simply throw blocks of ice into the water to keep it cool and nothing else.
The Inuit were referred to as "Skraelings" by the Vikings, which roughly translate to “wretches” (Diamond, 261). This term was also referred to the Dorset and Indian natives that the Vikings came in contact with as well. Because of the Vikings poor judgment, they lost all trading and learning opportunities that they could have gained from the Inuit. Whale hunting was a valuable talent that the Inuit had because of the whale’s many benefits. The whale blubber could be used as fuel and lighting, and the meat provided large amounts of food for them to eat (Diamond, 258).
It is a useful way to protect grizzly bears, also it is beneficial to promote the development of tourism industry. The grizzly bear hunting has to be stopped and they can be put into zoos all around the world. Many people love closing to the nature and they love animals. It is convenient for them to watch grizzly bears in the zoo. However, some hunters are very covetous and they want to make money by using animals.
Another reason of the killings is that some farmers shoot at them to protect their cattle (there are other ways to send the leopards away, killing them is not the solution). Finally, there is Global Warming. We all know about it, and the problem is not only for snow leopards, but also for everyone that lives in this planet. For example, Snow leopard´s habitat is being destroy due to the high temperatures, and it is estimated that, if it continues like this, in the near future a third of their habitat will be
CONCLUSION The extinction of wolves is becoming an increasingly probable reality and will have a massive impact on the earth’s ecosystems if intolerance is not decreased. Wolves have always suffered from negative stereotypes. The problems surrounding wolves stem from misrepresentation.
At this point, Luckovich asks the audience to look at the real issue because the sun on its own cannot cause such devastation. For this to happen, the audience goes back to the text to analyze the deeper meaning. Happy Earth Day says one bear to the other and everything falls into place. Now the audience has a clue to what is happening and it all points to global warming which is an issue that is affecting their planet. They realize that the situation has become very dire if it is melting the ice in the coldest regions of the earth.
These food options give the grizzly bear and evolutionary advantage, but it’s not the only one. Polar bears don’t like being in warm climates and tend to wind down when its warmer, so when the climate starts to get warmer they go into hibernation whereas the grizzly bear goes into a state of dormancy. Hibernation is when the animal is in a state of inactivity that decreases its metabolism or metabolic rates. The organism’s body temperature, heart rate, and breathing all slows down. Hibernation may last a few days, weeks, or even months.
Unfortunately, the amount of sea ice is beginning to fall, and the number of Polar Bears is falling with it. The cause, climate change, is a controversial issue that needs to be addressed. It will soon cause Polar Bears to become endangered and even
The majority of people wanted to exterminate Gray Wolves because they were very frightened of them, and because the wolves ate farmer’s domestic livestock. The desire to exterminate was strong until interest in environmental conservation took place in the 1960s and 1970s. As study into environmental conservation developed, scientists discovered without wolves present in Yellowstone to hunt and kill prey, the elk started to overpopulate. Overpopulation was a problem because the elk were eating all the young willow trees. Overconsumption of willow trees affected the habitat of many other animals and plants in harmful ways; therefore, the ecosystem became unbalanced.
In both of these articles by Christine Dell’Amore and Matt Miller, they discuss how these top predators impact the island, why they are they important, and should humans interfere? On the island of Isle Royale, there is a variety of animals that mostly just consume vegetation; therefore, they need wolves to balance out the food chain. But, the island is only accessible during the winter when stable ice bridges are created. Unfortunately, the ice bridges have not been forming due to warmer winters. Leaving a small count of wolves on the island with no new genes to mix in.
Ice cores also have to do with climate change when ice cores fluctuate the temperature rises leaving the mammoths in terrible conditions. So we are always weary if another ice age occurs. I think that another ice age will probably occur in a couple of centuries since the climate seems quite
