Gold may be beautiful and valuable, but some mining operations to extract the precious metal are seriously dirty.
The first commercial mission to harvest resources from asteroids could be launched within five years, as Luxembourg’s government works on joint missions with two U.S. space research companies to prospect for water and minerals in outer space through robotic missions.
In 2014 Italian photojournalist Luca Catalano Gonzaga went to Indonesia and spent ten days inside what he calls “the womb” of the Kawah Ijen volcano in East Java. Here, men toil in arduous conditions to mine sulfur from the depths of the crater—effectively breaking their own bodies in the process.

Rare earth elements are hard-to-find metals that we need for batteries, solar cells and electronics. These days, they’re mostly mined and processed in China. But it wasn’t always so. The history of rare earth elements is surprising, and some of it even takes place in America’s backyard. In fact, there is still a rare earth mine in the US.
If you were ever wondering how much land mass had to be moved to produce that diamond engagement ring, this series of photos should help put things in perspective.
