(March 25, 2011) Chinese geologist and environmentalist Fan Xiao has sent a letter to high ranking Chinese officials, urging them not to destroy the rare fish conservation zone they’ve created on the Yangtze. Plans are in the works to build the Xiaonanhai dam within the conservation zone, which would be the second time the Government redrew the zone to accommodate dams. Building the dam would violate the government’s own environmental protection rules, and would put over 100 rare species of fish at risk. He calls for public hearings and an administrative review, in hopes of convincing officials to abandon the plan.
