DISTRIBUTION OF RARE EARTH METALS

Diagram
[Map sketch with labels: Nickel and Cobalt in South America, Lithium in Australia, Lithium in small island region]

→ Rare Earth metals like Nickel and Cobalt are found in South American countries like Bolivia, Peru, and Argentina → Lithium is abundantly found in Australia. → Recently, lithium has been discovered in J&K, India → China also has reserves of rare earth metals

ENVIRONMENTAL IMPACT OF EXTRACTION

→ Mining requires huge amount of water. This leads to water scarcity. → Dust pollution also happens due to mining. → Land degradation and soil quality degrades due to mining. → Air pollution due to use of mining vehicles. → Habitat of flora and fauna gets disturbed, causing imbalance in the environmental ecosystem.

Thus, extraction of rare earth metals must happen in a sustainable manner.
