Pollution Turns Argentina Lake Bright Pink

TRELEW, ARGENTINA - A lagoon in Argentina's southern Patagonia region has turned bright pink in a striking, but frightful phenomenon experts and activists blame on pollution by a chemical used to preserve prawns for export.

The color is caused by sodium sulfite, an anti-bacterial product used in fish factories, whose waste is blamed for contaminating the Chubut river that feeds the Corfo lagoon and other water sources in the region, according to activists. Residents have long complained of foul smells and other environmental issues around the river and lagoon. "Those who should be in control are the ones who authorize the poisoning of people," environmental activist Pablo Lada told AFP, blaming the government for the mess.
