An indigenous group in Argentina's Patagonia are suing some of the world's largest oil and gas companies over illegal fracking waste dumps thought to be harming the environment in their ancestral lands.
Members of the Mapuche community spoke about their concerns close to Anelo in Neuquen Province on Thursday.
The waste is said to have originated from the Vaca Muerta site, one of the world's... Еще largest shale-oil and shale-gas deposits.
Environmental group Greenpeace recently released a report accusing multinationals and other corporations of flaunting regulations. This included an illegal open-air dump the size of fifteen football fields owned by waste treatment company Treater Neuquen.
Its proximity to Anelo (5 km; 3.1 miles) and nearby water supplies attracted the attention of activists, who have tried to document the environmental damage.
In December, the Mapuche Confederation of Neuquen filed a lawsuit against Exxon, Total, Pan American Energy (which is partially owned by BP) and Treater.
The companies were accused of putting the sensitive Patagonian environment, local wildlife and communities at risk.
They responded by distancing themselves from Treater and defending their operations as legal.
Authorities have since raided the waste treatment plant in their attempts to mount a case.
