"In April 2018, the Trump administration announced Alaska’s Arctic National Wildlife Refuge was open for business. By June, two Alaska Native Regional Corporations and a small oil company had already jointly applied to conduct extensive seismic testing in the refuge next winter.
Seismic blasts—loud sonic explosions fired through the ocean—map the seabed floor for oil and gas deposits to extract. Opponents, like the Wilderness Society and the group Polar Bears International, say the testing has deleterious effects on the land and the wildlife. The Canadian government has opposed opening up ANWR for these reasons as well.
Some Alaska natives support the oil exploration for its economic potential, while others, like the Gwich’in nation, argue that it would disrupt the caribou herd upon which their traditional diets—and much of their culture—depend."
