"A Bolivian lake that was once an oasis of natural beauty full of thriving wildlife has become a waterless basin full of plastic waste. Lake Uru Uru in western Bolivia is covered in mountains of rubbish including plastic bottles and other man-made garbage for as far as the eye can see. The piles of rubbish are believed to have come from the nearby city of Oruro via the Roso Canal, where residents dump their waste. The lake's water is tinged black and brown because heavy metals such as cadmium, zinc, and arsenic have leached from nearby mines into the reservoir. Limber Sanchez, an ecologist with the regional Ecological Centre and Andean People (CEPA), said materials leached from the San Jose Mine had destroyed the purity of the water. He said: 'Alongside the plastic is also the impact the acidic water from mining that has come from the San Jose Mine that almost 365 days of the year empties directly into our Lake Uru Uru.' Sanchez said Uru Uru was hit with a deadly combination of urban contamination, mining contamination, and climate change, which as caused the lake to shrink."
