Chile's glaciers have receded rapidly in the past few decades, reportedly endangering the water supply in certain parts of the country. At the same time, the country's copper industry is seeking to expand, which some worry could further erode the remaining glaciers. The country has passed a National Glacier Policy, but that has not satisfied environmental advocates. The policy "specifically states that impacts to glaciers may be acceptable if required for the interest of the nation, a condition that is not defined by the policy," said Alexander Brenning, an associate professor of geography at Canada's University of Waterloo.
