Environmental campaigners are delivering a letter to 10 Downing Street as protests take place in London today against 'fracking' - a controversial gas extraction method.
Activists are worried 60% of the countryside could be dug up to find gas - something which the Department of Energy has dismissed.
They are calling for a ban on exploration and development of shale gas and coal bed methane which they say damages the environment.
Demonstrators say they will also put up a 7.2m dummy rig outside parliament as part of the protest.
