The World Wildlife Fund…has called for an emergency meeting with the Mekong River Commission (MRC) in the wake of Laos' decision to proceed with a second dam on the river. There are fears that this move will seriously undermine the River Commission's efforts to protect the river and its rich fish life. It could also strain regional ties, given that the Don Sahong dam is likely to have severe environmental repercussions in Cambodia and Vietnam, where millions of people rely on fishing and growing rice in the lower reaches of the Mekong…WWF said the Don Sahong dam would block the only channel available for dry-season fish migration on the mekong "putting the world's largest inland fishery at risk"…
