My Lords, the noble Lord, Lord Teverson, and the noble Baroness want to give the Secretary of State powers to set targets separately in respect of “terrestrial biodiversity” and “marine biodiversity”. Actually, the definition of “natural environment”, as contained in Clause 43, makes clear that it includes the marine environment as well as the terrestrial and water environments. I do not support this amendment because it is unnecessary. Furthermore, it appears to exclude the crucially important area of the water environment.
I also do not support Amendment 7, in the name of the noble Baroness, Lady Bennett of Manor Castle. It may well be that efficiency is improved by the increased use of some resources and reduced use of others. This depends on the availability and cost of various resources. The noble Baroness’s amendment is too prescriptive and would constrain the Secretary of State unreasonably in the exercise of his powers.
I welcome Amendment 10, in the name of my noble friend Lord Randall of Uxbridge. It is regrettable that the Bill does not cover light pollution. As new road schemes are progressively introduced across the country, many of them are connected with existing roads by new roundabouts, often on high ground above the towns and villages to which they provide relief. They can be seen for miles. Highways regulations require that roundabouts be lit, unlike gradual road junctions. This is an increasing source of light pollution and has a significant effect on the urbanisation of the countryside. Although I am not sure how to measure the “people’s enjoyment” of the countryside, light pollution has a negative effect.
If my noble friend Lord Blencathra’s amendment were accepted, at least in some places, could the meaning of “nature” not be extended to include the soil and the organisms that live in it? In that case, Amendment 11 would be redundant.
Amendments 12 and 31, in the name of the noble and right reverend Lord, Lord Harries of Pentregarth, require the Secretary of State to set targets for the planting of new trees. He spoke with conviction in support of his amendments, but I believe that the Secretary of State already has the necessary power to set targets for tree planting, and I wonder whether this needs to be made a separate priority area.
Amendment 14, in the name of the noble Baroness, Lady Bennett of Manor Castle, seeks to add “nitrogen management” as a priority area, over which the Secretary of State must set a long-term target. Nitrogen is essential for both plant and animal life, but I am not sure that it is necessary to add another priority area because this is surely already included in Clause 1(3)(c), whether we call this “nature” or “biodiversity”. Furthermore, excessive use of nitrogen in fertilisers has already been reduced by more than a third since the mid-1980s.
Amendment 32, in the name of the noble Baroness, Lady Jones of Moulsecoomb, is terrifying, and I hope that my noble friend does not accept it. It seeks to reduce the amount of meat and dairy products that we consume by 20%. I know that the Committee on Climate Change has recommended that we reduce our livestock production, but I am very sceptical that this would have the slightest impact on the amount of carbon dioxide in the atmosphere. Certainly, growing more trees will help, but 65% of British land is suitable only for livestock grazing, and I believe British farmers will find that the growing middle classes in Asia will steadily recognise the quality of our meat products, opening up new and profitable markets for them.
We have grazed cattle and sheep in this country for thousands of years, and the state should not be in the business of telling us to eat less meat, whether through new draconian measures or the application of taxes that would reduce the profitability of our farms, driving farmers off the land and reducing the proportion of our food that is home-produced.
