Environmental campaigners held a protest outside County Hall in a rally against fracking.
Protesters gathered to urge voters to use next month’s Lancashire County Council elections to urge politicians to halt the rise of the industry in the county.
The county is expected to be the test bed for the gas extraction which caused earth tremors in the county and is linked with water pollution in the United States.
Tina Rothery, a spokesman for Residents Against Fylde Fracking (RAFF), said the activity would not remain focused on the Fylde coast where the firm has drill sites at Singleton, Weeton and Westby.
She said: “If you are living in Preston, Chorley, Blackburn or anywhere, then you need to think how this is going to affect you because it will not stay on the Fylde forever.
“People look at this and think it is a Fylde problem but if it happens in Lancashire it becomes the whole country’s problem.”
Helen Rimmer, a regional campaigner for Friends of the Earth which organised Saturday’s protest, said it would be lobbying candidates from all parties to back block the work.
Lancashire County Council would decide whether to allow commercial extraction of gas through fracking to take place.
Mrs Rimmer said: “So far the Green Party is the only one to commit to opposing fracking in Lancashire.”
