Question

Paul Nicklen waited patiently on a sheet of ice in the Arctic.  He was there to take pictures for National Geographic. Finally, he saw something big and white. It was a polar bear, swimming towards him in the icy water.
Paul lay down-on the ice to get a better photo, but the polar bear jumped out of the water and tried to attack him! Luckily for Paul, the ice cracked or broke and the bear fell back into the water The polar bear wasn’t so lucky. It couldn’t get a meal and had to swim farther away to find food.
To understand the polar bear’s problem, you need to know two things about the Arctic. First, the Arctic is mostly ocean. Second , ice cover a lot of the Arctic Ocean. In winter, the ice form a thick, white sheet, but in summer, the ice becomes thinner and break into pieces. Sea ice is the key to survival for Arctic animals. However, because of global warming, Arctic temperatures are rising and polar ice is melting.
Polar bears need ice to hunt seals, their favourite meal. They stand on the ice wait for the seal to come up for air. As Arctic ice melts, polar bears have to swim farther to find ice floes, or large pieces of floating ice. Sometimes, bears have to swim more than 200 km to find an ice floe. Some bears cannot swim that far and sadly they drown.
On his last trip, Paul Nicklen saw three dead bodies of polar bears. Before global warming threatened Arctic ice, a dead bear was a rare sight, Paul is sad to see the dead bodies, wildlife experts thinks global warming will have a terrible effect on polar bears. In the future, polar ice will continue to shrink and endanger the bear. Some scientists believe 65 percent of the world’s polar bears will disappear by 2050. in other word, polar bears are in great danger.
