We have heard the hon. Gentleman speak at some length about the problems caused by the dumping of sewage sludge in the North sea. The essence of politics is that one not only criticises, but comes up with a solution to the problem. The hon. Gentleman has said that 3·5 million tonnes of sewage sludge are dumped in the North sea—that is an awful lot of sewage sludge—so what would he do about it right now? Would he spread it on the land? Would he build incinerator plants? What would he do about the problem between now and January 1993?
