Will Polar bears be extinct in 20 years??

Question

Will Polar bears be extinct in 20 years??

Answer 1

Absolutly not.  I live in Alaska and have spent allot of time along the North Slope where polar bears live.

Polar bears are a subspeices of brown bears that adapted to life on the ice, swimming in cold water, and surviving the cold climate.  Even is global warming was true and all the ice melted today - there would be thousands of them stranded on the land.  These bears would survive quite well - lots of them live on the land in summer and ice in winter - they would simply migrate a bit south and feed on caribou rather than seals.  If the ice did not return in a few thousand years - they might not be white year round anymore - probalby white in the winter and then shed and be brown in the summer to match the tundra.

30 years ago, before the pipeline, there were 5,000 polar bears and 600,000 caribou around that area.  Today there are 25,000 polar bears and over 2,000,000 caribou.............. so it's not like their population, or potential food sources are in jeporady.

Just our Democratic Congress at work........ and this recent issue about polar bears is just one reason that Congress's approval rating is 9%.

Answer 2

could be.There are several factors. One of them is global warming. If we cannot concern about how to preserve energy without causing destruction of the environment, the global warming will get worst. What it has to do with polar bear?

well....polar bear lives at northern Arctic, where ice floes located. If the global warming continues, the ice melts, makes the polar bear having difficulties for putting feet to stand or walk. Polar bear cannot live forever in water, they need stable ground. With this situation, polar bear could not survive longer. Now how do we suppose to save polar bear?

We can do some things that could reduce the global warming.

First,  try to reduce carbon emision (use the public transportation instead of private vehicle).

Use the papers, tissue efficiently. Do u know that paper & tissue production needs timber to be cut down could cause global warming?the carbon dioxide is not transformed completely because of the loss of plants. The increase of the CO2 amount in the air could speed the global warming.

Reduce the use of air conditioner or any other equipment which needs CFC (chlorofluorocarbon) as many as possible.  

I hope it helps.
