Argentina lakes turn pink but the outlook not rosy, environmentalists say

Buenos Aires: Two lakes in a far-flung coastal region of Patagonia, in Argentina, have turned fluorescent pink, as of yet unexplained phenomena that local environmentalists fear could be harmful and caused by industrial contamination.

The lakes, located near an industrial park on the outskirts of the Argentine city of Trelew, sprawl across a dusty, desert-like plain and are largely undeveloped. Officials with the municipality of Trelew recently uncovered a truck dumping waste in the watershed, according to posts made by the city on social media. Authorities gave conflicting views to local media, however, on whether the sudden change in color of the lakes was harmful. Environmentalists were more concerned.
