images of Earth from space, glowing against a dark background, with lights indicating larger population centersResearchers found that one billion people may face freshwater shortages by 2050, due to a combination of population growth and climate change. The shortages will likely impact freshwater flows, which can impair river ecosystem health as well as local fisheries.
