I am sorry, but I cannot give way any more or I would lose the rest of my time.
The other question is what happens with those large amounts of wells in terms of the fracking process? That process involves the use of between 2 million and 7 million gallons of water, and 5,000 gallons of chemicals, per frack; whether we know what is in the chemicals or not, that is the sort of amount of chemicals needed. As has been said, that water cannot be injected largely into
seams deeper than the fracking itself, as is the case in America, but would have to be disposed of by other means. Also, unless the fracking companies brought the water with them, water would have to be taken from the water table within the area where the fracking was taking place, which has implications for the integrity of the water tables in those particular parts of the country. That is an important but largely forgotten point.
The final thing that I want to say, given the short amount of time I have, is about the policy implications of going for a large amount of fracking. If we went for a large amount of fracking, as I have said we could perhaps supply—over a period—10% of overall UK gas supplies. If we went for a large programme of anaerobic digestion, we could provide 10% of the domestic gas supply. A farm-sized anaerobic digestion plant costs about £2 million to build—
