The more electric cars that are produced means the more lithium will need to be mined.
Bloomberg published a report detailing how the boom in lithium mining is irreversibly destroying the local environment of northern Chile’s Atacama desert. Mining for lithium means removing large amounts of water, which means depleting the water supply for locals. According to the report, the Tilopozo meadow in Chile used to be a shelter for shepherds traveling at night, yet has become barren due to lack of grass or water. That puts a severe strain on local farmers.
They are also mining for lithium in Cornwall, and I don't know what the impact of that will be on the environment.
Will we ever reach a point in time when the only resources we need for energy are the sun, wind and water?
