Global Warming Effects on Polar Bears

Since late 1800s earth’s average temperatures worldwide has risen by 1.4 degrees Fahrenheit. Global warming is gradual heating of the earth’s surface, oceans and atmosphere. We are causing the global warming by burning fossil fuels such as oil, coal, and natural gas, this fuel is used in factories and other places. Global warming has a dramatic effect on wildlife animals, such as polar bears, penguins,  turtles and  many other animals. Today we are going talk about the global warming effects on polar bears. The polar bear is listed as a vulnerable species.

The polar bear is a burly white bear that lives in the lands surrounding the north pole. The polar bears is a vulnerable species because their population is decreasing. Population decrease is due to sea ice melting, which is attributed to global warming. Polar bears hunt in the fall when the sea is frozen, because when the ice melts in spring, it is hard for them to hunt. During summer polar bears live on land and sometimes they can’t find food so these bears eat little or nothing. Due to hunger and sea ice melting the polar bear are dying. The ice is melting away from the shore, giving the polar bear difficult accessibility to hunt and travel to places. Polar bears are losing their weight due to melting ice and difficulty finding any food.

Global warming is effecting many things in earth. Humans are causing global warming and we can reduce this by not burning fossil fuels and use green electricity. Purchasing cars from the car companies that are making cars that run on electricity that don’t cause air pollution. If we stop burning fossil fuel and don’t cause more pollution we can save our earth.

How can you stop global warming faster?

What energy can we use that does not cause pollution?
