Climate change experts warn that shale gas is still just a fossil fuel, and thus a source of carbon dioxide – the prime driver of global warming. Environmentalists have also raised concerns about the impact of extracting the gas. They point to incidents of drinking water allegedly becoming contaminated with the chemicals used to extract the gas, and even shale gas itself, leading to tap water becoming flammable. Such fears have already prompted the French government to impose a temporary ban on shale gas extraction.

Shale gas could solve the fuel crisis.
