The British government announced Saturday Nov. 2, 2019, that it will no longer allow fracking because of new scientific analysis that casts doubts on the safety of the controversial practice, but some critics said the measure falls short because it is not a permanent ban.

FILE - In this undated file photo provided by the U.S. Fish and Wildlife Service, caribou from the Porcupine Caribou Herd migrate onto the coastal plain of the Arctic National Wildlife Refuge in northeast Alaska. Opponents of oil drilling in America's largest wildlife refuge have a message for oil drillers and the people who finance them: Don't become the company known for the demise of America's polar bears. The Department of the Interior hopes to conduct a lease sale in the Arctic National Wildlife Refuge by the end of the year but environmental groups say they will challenge those plans in federal court and the court of public opinion. Congress did not take a direct vote on opening the refuge. Instead, a provision for lease sales was included in President Donald Trump's Tax Cuts and Jobs Act in Dec. 2017.
