Anti-fracking protest. Members of the group 'Ban Michigan Fracking' picketing the Lansing Center in Lansing,Michigan,USA. They are protesting against an auction of oil and gas leases for state-owned land. Fracking is a drilling technique used to extract gas from shale deposits. A mixture of sand,chemicals and water is pumped under high pressure from the surface to underground horizontal wells. The pressure forms fissures (fractures) in the shale,allowing gas to flow to the surface. Photographed on 29 October 2014 | |
