Drones are also being used to help animals in trouble of becoming extinct, or disappearing forever. In Africa, drones have been designed to help find poacherspeople who illegally kill rhinoceros and elephant for their horns and tusks. It has been a year of insects and animals in trouble of disappearing-- from rhinos to bees and tigers.
At the North Pole, Arctic polar bears are threatened because climate change is melting ice there. It means they are losing their territory at the top of the world. Meanwhile, at the bottom of the Earth, scientists found fish and other sea creatures under the ice on the Ross Ice Sheet, off Antarctica. They were surprised to see organisms swimming and crawling in icy waters under the ice sheet. It is the farthest south that fish have ever been seen. Unfortunately, the same cannot be said for some warmer waters. Scientists studied coral reefs in the U.S. Virgin Islands in the Caribbean. They also studied reefs in Hawaii. And they found that sunscreen from people swimming around the reefs is killing the beautiful coral. Other things harming the coral include pollution, warmer seas and overfishing.
