Hydraulic fracturing — or fracking — has been a hot topic of debate since it becoming commonplace in the 1990s.

A slew of chemicals, sludge, and sand are used to produce fractures in underground rock. Pollutants from these substances can get into the air and cause damaging health effects in people living around fracking centers.

Although fracking wells are drilled far below where we access drinking water, fracturing can create conduits through which toxic or radioactive material can rise and contaminate our water sources.

Wastewater injection causes more frequent earthquakes

A 2014 paper in Annual reviews of Environment and Resources found that, as fracking and other unconventional energy extraction processes started to increase in the central US, scientists started detecting about 100 earthquakes per year at magnitude 3 or higher.

But some scientists suggest that methane — which is another greenhouse gas — can leak from wells, basically counteracting the reduced CO2 emissions.

Natural gas may be cleaner than oil, but it’s still a fossil fuel. And the world’s ability to combat climate change comes down to weaning off its reliance on fossil fuels.
