【推荐1】In the wild, polar bears spend much of their lives wandering pack ice (浮冰群) in search of food. These bears have adapted to a high fat diet from ocean-going animals: they are rapid and dangerous swimmers, allowing them to easily catch animals as food. Each summer, as the pack ice starts to become smaller, polar bears draw closer to land to give birth to and care for babies. Many give up food during this period, hunting again when the ice returns and living on stored fat.

Pack ice is decreasing globally. When it does form, it disappears more quickly, and tends to be thinner as well. In 2004, several polar bear deaths by drowning were recorded. The bears had been trapped on faraway areas of floating ice, and had tried to swim for land. Due to the disappearance of the ice, they were tired and drowned before reaching shore safely. This problem is likely to grow as the pack ice becomes smaller.

The disappearance of the ice has other impacts for polar bears: they are losing their natural prey (猎物), who are also affected by the loss of habitat. The bears are not very good at catching land animals, and must compete with other species for these food sources. Land animals also don’t provide the high fat diet that polar bears need, which may lead to hunger. Hungry mothers may not be able to provide their babies with the nutrition needed, which will further contribute to the drop in polar bear population.

The deadly factors brought about by global warming put polar bears at risk. Drops in birth and survival rates have already been documented, and biologists are increasingly concerned   about the animals’ odd behavior as a result of the loss of their natural habitat. Environmental organizations believe a global effort is needed to fight against global warming before it is too late for polar bears, as well as many other species that call Earth home.

【推荐3】Here are 5 actions you can take to make a difference to our environment.

1. Use fewer napkins.

The next time you’re eating, don’t take a bunch of napkins when you need only one. If every American used an average of one less napkin every day, it would prevent the use of more than a billion pounds of napkins — enough to fill the Empire State Building — from ending up in landfills. Use fewer napkins, and you’ll cut down on waste.

2. Think before flushing.

Don’t flush wastefully. By avoiding just one flush a day, you could save about 4.5 gallons of water. That’s as much water as the average person in Africa uses to bathe, drink, clean, and cook for an entire day.

3. Avoid wasting food.

Eat Thanksgiving leftover-Don’t let them spoil. If every US household reduced food waste by the weight of.one slice of bread, the money saved would be enough to pay for three meals a day for a year for every homeless child in the U.S.

4. Kick off the shoes

Leave your shoes at the door when you come into your home. Unwanted fertilizers, lead, and poisonous cleaners found on outdoor surfaces can hitch a ride on your shoes and track through your house.

5. Save energy

When you go out, try to use public transport. If you close the bathroom door when you take a bath, you will keep the room warmer, Your bath water’s heat stays trapped in the bathroom. The water also stays hotter and longer, so you don’t need to add more hot water. Save energy: Close the door.
