Bolivia’s lake of plastic: Even waterways high in the Andes cannot escape the scourge of pollution

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 Tagarete river, where residents dump their waste, and from local mining companies.

The polluted waterway has no outlet to the sea, so rubbish that has piled up in the lake in recent years is now stuck. 

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.  

The lake, which is located over 4km (2.5 miles) above sea level in the Andes mountains, used to be known for its fishing communities and boasted the largest population of flamingoes in the region.

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. 

The lake lost nearly all of its water during a long drought in 2016. At the time, experts described the drought as an environmental disaster caused by climate change and the over exploitation of the water source by nearby mines

Years of pollution have damaged the lake’s fragile ecosystem and pushed any remaining wildlife into only a small proportion of habitat. 

Resident Vicente Ramos, who grew up near the lake said that before plastic waste started taking over the habitat, ‘you could fish, you could do anything’.    

He added: ‘There were birds here and now the birds are dying because of the pollution and all the things that are happening.’

Residents remember a time when the lake was clean and home to many thriving wildlife, including birds and fish

Local villagers have raised concerns over waste management in the region and worry about how the lake will continue to be polluted in the years to come

Local and national authorities have agreed to try to clean up the lake and encourage wildlife to return to the area, but ecologists warn the efforts may be too little too late

Local and national authorities have agreed to try to clean up the lake and encourage wildlife to return to the area. 

Oruro Mayor David Choque said authorities planned to ‘show a different picture’ of the area.  

He said: ‘We are always working on behalf of the environment, in our culture we must tell the citizens to no longer throw out this type of waste.’ 

The lake lost nearly all of its water during a long drought in 2016. At the time, experts described the drought as an environmental disaster caused by climate change and the over exploitation of the water source by nearby mines. 

Without urgent action ecologists, including Sanchez, warn the lake may never return to its former glory. 

Mayor Choque said part of efforts to clean up Lake Uru Uru would involve getting residents to stop disposing of their plastic waste in local waterways

Experts warned of the environmental disaster facing Lake Uru Uru as a result of the build up of rubbish and leaching from nearby mines as early as January 2010 (pictured, a local villager walks over the rubbish)

The lake used to have a surface area of 214 km², but much of the water was lost in a lengthy drought in 2016 (pictured, Roberto Tarqui walks over the rubbish)

The lake was formed in 1962 and had attracted thousands of tourists who enjoyed boating and fishing in its waters until plastic waste started to build up (pictured, a local resident surveys the garbage)

Nearby Lake Poopó is also struggling to mitigate the results of climate change, but has not faced the same issues of waste build-up as Lake Uru Uru (pictured, residents of villages near Lake Uru Uru)
