M.PRESS/ The recent polar wave has killed an estimate 6 milion freshwater fish and thousands of alligators, turtles and river dolphins. Scientists are calling it Bolivia's biggest ecological disaster. “In the rivers near Santa Cruz there's about 1,000 dead fish for every 100 meters of river,” reported one scientist. The decomposing fish have polluted the Grande, Pirai and Ichilo rivers so badly that officials are providing alternative sources of drinking water for towns along the rivers' banks. Fishermen have also lost their main source of income.
