Anyone who says that hydraulic fracturing is without risks is quite certainly wrong. Similarly, anyone who says that banning fracturing in the UK has less risk is quite certainly wrong.
What can be said is that in the UK, shale gas rocks are around twice as deep as is the case generally in the USA and the rocks are harder. We also have dramatically better technology and policing by the Environment Agency.
Currently, we ship shale gas from the USA and Middle East in specially constructed ships. If you heat your home with gas, ask yourself if it make environmental sense to ship gas half way round the world, from places that really do use much less safe production than we will do, and export the jobs.
