The Anti Fracking movement is a political movement which seeks to ban the practice of extracting natural gasses from shale rock formations to provide power, due to its negative environmental impact. An anti-fracking movement has emerged both internationally, with involvement of international environmental organizations and nation states, and locally in affected areas. Through the use of direct action, media, and lobbying, the Anti-Fracking movement is focused on holding the gas and oil industry accountable for past and potential environmental damage, extracting compensation from and taxation of the industry to mitigate impact, and regulation of gas development and drilling activity. As part of the UK-based Frack Off campaign, three men blocked a convoy of trucks carrying drilling equipment to a site near Blackpool in September 2018. Two were sentenced to 16 months in prison and the third 15 months, after being convicted of causing a public nuisance. A fourth defendant was given a 12-month suspended sentence after pleading guilty to the same offence. They were the first environmental activists to receive jail sentences for staging a protest in the UK since the Mass trespass of Kinder Scout in 1932. On 17 October, all four men were released over the anti-fracking protest by Court of Appeal judges.
