My Lords, I will introduce the words “climate change” at this point, simply because it seems, to follow on slightly from the noble Lord, Lord Deben, that constancy and vigilance will be particularly important. If one thinks of the extremes of climate change that we are already experiencing—and there is every indication that it will get much worse—the constancy that the Minister is speaking about becomes extremely important. At times of drought and of far too much rain, many things start to go wrong. Drought is the obvious one, as you do not have enough water, but when there is too much rain—I speak as somebody who lives on a farm—you start getting an enormous amount of run-off of chemicals
into the rivers, and things like that. Therefore, this constancy towards regulation, wariness for the future and extreme vigilance are incredibly important in this area.
