SIR - Whether some who are against fracking drive a car, use a gas cooker or drink from a plastic bottle doesn't lessen the need to be against fracking, reduce dependence on fossil fuels or want to see less plastic used in packaging. And it doesn't devalue the 'message.'

Everybody is inconsistent and, even at times, hypocritical in their behaviour to some degree. But, what is most important are the facts and that expert scientific opinion has told us what must be done to address man-made climate change. And their latest message is we've not got long to do it. This includes saying, "No," to fracking.
