In Washington, D.C., dozens of indigenous leaders from Alaska and other parts of North America will hold a protest at the Capitol building today, demanding Congress drop Arctic drilling from their massive rewrite of the U.S. tax code. A little-known provision tucked into the Senate’s version of the tax bill would open one of the world’s last pristine wildernesses—the Arctic National Wildlife Refuge in Alaska—to oil and fracked gas drilling. The Arctic Refuge is rich in biodiversity and home to caribou, polar bears and musk oxen. It has also been home to indigenous people for thousands of years.
