Waste from mining and processing, including residual minerals and chemicals, can also contaminate water in nearby communities. Current processes for extracting lithium — a critical mineral used in both electric vehicle (EV) batteries and solar panels — are particularly water-intensive. Take the "lithium triangle" in South America.

This is one of the key drivers for the increasing demand for the mineral, which is set to soar by as much as 200% by 2020. This demand prompted a 25% rise in the price of graphite between December 2016 and December 2017. Another driver is graphene, a recently developed 'super-mineral' that could dramatically improve battery technologies.

Over the twenty-year period, mining in protected areas has risen from 225 Mt to 480 Mt, a 113% increase. Further, the figure suggests that there was a significant surge in mining in the 10–15 km range from protected areas. The large increase of mining activities in protected areas is partly explained by new sites.

Today, there are two main ways to pull lithium from the ground. Until recently, most lithium mining occurred in Chile, where lithium is extracted from brines: salty liquid found at the Earth's surface or underground. To extract lithium, that liquid is pumped from the earth and then placed in pools where the water can evaporate, leaving behind ...
