That is a very fair point, although I hesitate to debate those issues, given such an expert audience. However, he would surely also accept that there is some evidence that some of the farming methods that have been used have been damaging to the environment. In that sense, those who would argue in favour of organic food surely have a point in saying that it can have a positive contribution. I suspect, whatever we say today, that those who like to have organic food will continue to want to enjoy it. We should not get in the way of consumer choice in that sense.
The word “environment” covers a lot of ground, but the specific issue that has been raised by critics of factory farming in the United States is the significant loss of biodiversity. I understand the point about the use of land made by the noble Lord, Lord Taverne, but the fact is that progressive loss of biodiversity is a serious matter. It is being contributed to by farming. I hope the Minister can confirm whether biodiversity is part of the Defra programme. In Britain, where there is a lot of organic farming or no farming, there is much greater biodiversity. I see that in Devon, where I often go.
My Lords, my noble friend makes an important point. I realise that the noble Baroness is principally speaking for the Department of Health, but I hope, in her winding-up speech, she will cover some of the environmental impacts as well, because we have to look at the evidence in the round. I welcome the debate, and I hope that the noble Lord, Lord Taverne, will continue to come to your Lordships’ House with such entertaining issues in the future.
