The decline of wildlife along the Mekong River, and really in all of Southeast Asia, has reached crisis levels. Between widespread development and the Chinese desire to kill every mammal in existence, there isn’t much left. On the Mekong, home of many now rare and amazing species, we are at crunch time in what is probably a losing battle. Among the fundamental problems when it comes to aquatic life is that you have to convince fishermen that not killing as many animals as possible is worth their effort. The only way to do that is cash because for poor people, every fish, every deer, every thing period, counts toward feeding their families. Of course, paying off large segments of a population has never been tried and probably would not work anyway, but without state intervention or convincing people to not kill the last of these animals, the Mekong ecosystem will be pretty well denuded of animal life.
