Toxic Mega-Mining In Mexico: Death And Despoilment 500 Years On

And, as if the plundering of our riches were not enough, these companies, which vaunt their “green” and “socially responsible” credentials, leave a trail of death and environmental destruction in their wake. This can be seen above all in the contamination of groundwater with cyanide and heavy metals, and in the depletion of water sources due to the extremely water-intensive nature of mining (on average a single mine consumes 250 000 litres of water per day, which is equivalent to the amount that a poor rural family would consume in the space of 20 years).
