My Lords, I thank all noble Lords who have taken part in the debate this afternoon. We have heard some very passionate and powerful arguments, many in favour of this amendment. I also thank the Minister for his response, although I found it as disappointing as he found my amendment. In fact, I was reminded of the words of Francis Cornford, written over 100 years ago. In his chapter on argument, he said that there are many reasons for not doing something but only one reason for doing it, which is that it is the right thing to do. I strongly believe that in this case, the right thing to do is to support the amendment.
In his speech, the noble Lord, Lord Deben, reminded me of something I heard him say over 20 years ago when he was Secretary of State. He defined sustainability as “not cheating on our grandchildren”. One of the advantages that many noble Lords will share with me is that, as you get older, you have grandchildren. I am fortunate to have three wonderful grandchildren. But with that pleasure comes the responsibility to care about their future. This amendment is about caring for the future of our grandchildren. It is not just about birds, bees, butterflies and wild flowers, because the health of our grandchildren is intimately related to the health of the environment that we leave for them to live in. This is about a healthy environment for the future and about the health of future generations. So, in spite of the arguments for not doing so, I wish to test the opinion of the House.
