Severe pollution turns Argentina lake pink



PATAGONIA:
A lagoon in this Argentine southern 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 antibacterial 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.
