Endangered Polar Bears!!!!

The main reason why polar bears are going extinct is because the ice caps are melting, and they are running out of space to live. When the temperature gets warmer, it melts the ice where they live, so they could drown. Polar bears have to be able to handle 100 degrees difference in temperature between seasons. Researchers believe there are between 20,000 and 40,000 polar bears left.

sustainability

1.) Sustainability is an environment's ability to support a trend or way of life.

2.) It means having resources like gasoline for aspects of daily life including travel, production of all their needs, and others.

3.) Since oil (our chief energy source) is used for the production of most goods in at least some way, not having enough of it would mean not being able to develop as much as we were once able to.

4.) They could live closer to where they work; use land better by doing such things as farming on it; and buy locally made products so then out-of-town materials get less funding and therefore would not be as prominent, which would be a good thing because the longer delivery of those products makes them more costly.
