While families across the U.S. continue suffering from the effects of the country’s fracking boom, the practice is expanding to other nations.

Naturally, earthquakes, sickness and resistance will accompany that expansion. Take South Africa, for example, where the Karoo Basin is believed to be covering 400 trillion cubic feet of shale gas. A moratorium on natural gas exploration was lifted in 2012, prompting companies to line up for a piece of what should be a large pie.

Earth Focus takes a look at how fracking has gone global and what that as meant to Poland, the United Kingdom and South Africa.
