My Lords, I thank the Minister for his reply. Does he agree, though, that there is a huge challenge for the Government, the EU and the world summit in that the earth summit builds on the good principles established at Rio, of which the Minister has outlined some, but these principles, including the precautionary principle and the polluter pays principle—which I believe the Government have signed up to; at least according to their website for the earth summit—are often ignored, challenged or ruled out of order by the World Trade Organisation? What are the Government doing to try to bring into a focused aim the two parallel universes that are dwelt in by these different organisations?
