    The Environmental Impact of Aluminum (And Why it’s Still

    Aluminum (or Aluminium, if you’re not from the US) is an abundant element within Earth’s surface— but getting it out of the ground is an arduous process, requiring heavy machinery to plow up acres and acres of land. Fortunately, the environmental impact of that process can be somewhat balanced out by post-mining rehabilitation, efficient recycling, and generally reducing our consumption
