Polar Bears will be Protected in Alaska

Grammar, Vocabulary & Pronunciation

      The US government says land that oil and gas companies want to drill in Alaska is a crucial home for polar bears. Environmentalists hope this announcement will help save the endangered animals. Now the US government has designated nearly half a million square kilometres in Alaska as critical habitats for the polar bear. It covers an area of roughly twice the size of the United Kingdom, and it means any proposed economic activity there, must be weighed against its impact on the bears' habitat. It includes some of the Chukchi and Beaufort Seas, exactly where the oil company, Shell, wants to drill.
