The Watershed Alliance of Southwest Washington will offer a free screening of “Water for Life,” from 4:30 to 7 p.m. April 22 in the Columbia Room at the Vancouver Community Library, 901 C St., Vancouver. “Water For Life” tells the story of Berta Cáceres, a leader of the Lenca people in Honduras; Francisco Pineda, a subsistence farmer in El Salvador; and Alberto Curamil, an Indigenous Mapuche leader in Chile, all of whom refused to let industry and transnational corporations take their water for mining, hydroelectric projects and large-scale agriculture. Pizza will be provided, including gluten-friendly and vegan options. Attendees should bring their own water bottles. Register at thewatershedalliance.org/?portfolio=film-series.
