And yet, crucial as they are, extracting these elements from the earth is linked to some disturbing environmental impacts. Rare earth elements can often be found, but in many areas, it’s not economically feasible to extract them due to low concentrations. Much of the time, extracting them requires a method called open pit mining that exposes vast areas of land. This form of mining destroys huge swaths of natural habitats, and causes air and water pollution, threatening the health of nearby communities.
