Fracking will be top of the agenda at a public meeting in Derbyshire.
Residents of Hope Valley are being invited to find out more about the controversial practice at an event next Thursday, April 3.
Local expert Royston Sellman, who has researched the environmental impact of fracking, will lead the talk at Hope Valley College, Castleton Road, at 7.30pm.
It has been organised by the Sheffield and Hope Valley branches of the Green Party.
While no formal application has been submitted to drill for gas in the Edale valley, based on a vast bed of shale, campaigners believe it may only be a matter of time.
Activist Charlotte Farrell said: “Fracking companies have already tried shale gas exploration in the South Downs National Park.
“We want to make sure if they apply to start testing here, residents understand the associated risks.
“These include known environmental impacts such as increased traffic, noise, and light pollution, as well as the unknown damage to people’s health.”
Sheffield city councillor Jillian Creasy will also be there to advise residents on how local authorities can respond to plans.
