Answer 1

In Spring 2008, the polar bear was placed on the endangered species list. The polar bear is the first animal that has been classified as endangered due primarily to global warming. Global warming is caused by carbon dioxide and other greenhouse gases that become trapped in the atmosphere. Oil and gas heaters, engines using oil or petrol (or gasoline) and coal-powered electricity plants all require fossil fuels that lead to global warming. Renewable energy sources or renewables that don't cause global warming include solar, wind and hydro-electricity power. The polar bear's habitat is more vulnerable to global warming than many other species. Polar bears live mainly on the sea ice in the Arctic. This is where they hunt for fish and build up fat reserves. When the ice melts many polar bears move to land and live off their stored fat. In the Arctic, global warming is causing the ice to melt slightly earlier and form slightly later. This results in a shorter feeding season for the polar bear. Some risk their lives to find ice. If they have to swim too far they will drown from exhaustion and hunger. The World Wildlife Fund estimates that over 25% of Arctic sea ice has disappeared in the past 30 years. It is important that animals such as the polar bear make it onto the endangered species list. Once they are on the list there are laws that protect these animals from being hunted for food or sport. Agencies also receive money and tools to protect the habitat and recover the species. The goal of removing the animal from the list is often achievable.

Answer 2

In spring 2008, the polar bear was placed on the endangered species list. The polar bear is the first animal that has been classified as endangered due primarily to global warming. Global warming is a form of climate change caused by increased levels of carbon dioxide and other greenhouse gases in the atmosphere. Various human activities contribute to global warming, such as the use of fossil fuels in oil and gas heaters, engines, and coal-powered electricity plants.

However, there are alternative energy sources that don't cause global warming, such as solar, wind, and hydro-electricity power. These renewable energy sources can help reduce the carbon emissions that contribute to global warming.

The polar bear's habitat is particularly vulnerable to global warming compared to many other species. Polar bears mainly live on the sea ice in the Arctic, where they hunt for fish and other prey. When the ice melts, many polar bears are forced to move to land and live off their stored fat. Due to global warming, the Arctic ice is melting slightly earlier and forming slightly later, resulting in a shorter feeding season for the polar bears.

Some polar bears risk their lives to find ice. If they have to swim too far, they can drown. The World Wildlife Fund estimates that over 25% of Arctic sea ice has disappeared in the past 30 years, further endangering the polar bear population.

Placing animals like the polar bear on the endangered species list is important because it provides legal protection from being hunted for food or sport. Additionally, agencies receive funding and resources to protect the habitat and the species. The goal of removing the animal from the list is often achievable through conservation efforts and the transition to renewable energy sources.

In conclusion, the polar bear's classification as endangered is primarily due to global warming, which is caused by human activities. The melting Arctic ice and shorter feeding seasons pose significant threats to the polar bear population. Protecting endangered species like the polar bear is essential for preserving biodiversity and ensuring the balance of ecosystems. Transitioning to renewable energy sources can help mitigate the effects of global warming and protect vulnerable species like the polar bear.
