May I ask the Secretary of State not to be too complacent about our streams and rivers in this country? Has she seen recent research? I have registered interests as the initiator of Greenstreams, which cleans up the rivers in my part of the world, and in environmental waste. Does she know that the old landfills are leaching tonnes of ammonia into our rivers every year? If we do not do something about it, the 27.5 tonnes of ammonia that go into one Oxford river every year will continue to do so, and that will happen all over the country.
