Taylor Manzi Topic: global warmings effect on panda bears and the arctic ice melting

SCRIPT:

What is global warming? Global warming is a scientifically adopted phenomena where the global temperature is steadily rising which is harmful to the earth. It also has a profound impact on species all over the world.Polar Bears, along with other arctic species are particularly at risk because their habitat is increasingly threatened by the rising temperature of global warming.

How global warming relates to polar bears: Some may think that global warming is no big deal, or that it is a big hoax, but taking a look at the harm that it has on polar bears in the arctic, is proof that it occurs. In the wild, polar bears tend to spend most of their lives wandering on pack ice. The go about searching for food, and just spending time to perch on the ice packs. Since polar bears are rapid aggressive swimmers, they are able to catch their prey quite easily, so they have adapted themselves to a high fat diet from ocean animals, such as seals.

Today, because of global warming, pack ice, is decreasing globally, leaving Polar bears are at a high risk. Due to the shrinkage of ice, polar bears are trapped on areas of isolated floating ice. They are sometimes forced to swim long distances to reach land. Because of the long distance swims, polar bears tend to become very tired and warn out very easily, and in several cases they end up drowning. The result of the rapid melting ice, means that polar bears and global warming is a fatal combination.

The shrinkage of ice has other effects on the polar bears as well. Polar bears usual prey are seals. The seals tend to dwell further in the ocean, which because of the lack of ice, leaves polar bears with longer, more strenuous hunts. To avoid straying far from home, they are being forced to scavange and eat carcasses of animals that have been previously killed by humans, or hunt land animals even. Polar bears are not adapted to catching land animals, and they do not provide the high fat that polar bears must obtain in their diets. This is a major harm because numerous amounts of bears are beginning to face starvation. The 11 ft. 1700 pound beautiful animals, are noticeably becoming much thinner and unhealthy.

Not only do polar bears rely on pack ice for hunting, but they also rely on it for denning and shelter. When the ice melts, the bears are left with barely anything. The bear cubs and parents have no means of shelter. As the ice melts at a rapid pace, The Arctic National Wildlife Refuge will become an increasing importance. The Refuge has the highest concentration of on-shore denning for polar bears in the Alaskan Arctic. They work hard to keep any pollution away from the bears, as well as work together to help from denns for the animals. The National Wildlife Federation has worked hard to protect the Refuge.

Also, while searching for food and habitat, polar bears have also clashed with humans. Human and Polar bear interactions are usually very rare, because the bears always perched on the pack ice. When the ice began to disappear, they began to show up around human inhabited areas looking for food and shelter. They would try to eat the carcass of the hunters kill, but they began to pose a threat to the human communities, and they would end up being slaughtered.

in some cases, we are the causes of the endangered polar bears. Due to our lack of respect for the environment, the gases and pollution also is a main leader in the death of polar bears. To help wildlife cope with the stress caused by climate change, natural resource managers need to take action to reduce non-climatic stressors. They are forced to limit the oil and gas development in, and near the polar bears habitat.

Polar bear deaths due to global warming, are of increasing concern, and new studies speculate that Polar bears may face possible extinction. We, as humans, being the number one creator of global warming, need to step up to the plate, and make better choices to end the possible extinction of polar bears, and the harms of global warming!

NOTES:

Is global warming killing the polar bears? The chief threat to the polar bear is the loss of its sea ice habitat due to global warming. However, the polar bear is also stressed by other human activity, particularly oil and gas development activities in its habitat

in some cases, we are the causes of the endangered polar bears. Due to our lack of respect for the environment, the gases and pollution also is a main leader in the death of polar bears.

Solutions: not only do we need to lower the pollution to help decrease this danger, but there are also othe rkey things that would help the cause. We need to help the wildlife deal with the climate changes. The over powering warm weather does a lot of damange to animals who are meant for the cold. Huge amounts of icebergs are melting, and the polar bears have no where to perch. The natural rescource managers must take into consideration on the ways to reduce the climate. -This means that they must limit the oil and gas development near the habitats of the bears. -bears rely on the icebers and the arctic for means of hunting as well as making denns too.(oil & gas) -As Arctic sea ice disappears, the Arctic National Wildlife Refuge on the Arctic coastal plain will become increasingly important for the polar bear. The Refuge has the highest concentration of on-shore denning polar bears in the Alaskan Arctic. This area should not be opened to oil and gas or any other development that would degrade essential polar bear habitat. The National Wildlife Federation has worked hard to protect the Refuge.
