My Lords, it gives me great pleasure to support every word that the noble Viscount has just said—a rare event.
I have recently joined a group of people who meet monthly to assess the health of the chalk stream that runs through their village by counting river flies, and the experience has been a real pleasure. There is nothing as satisfying as seeing a healthy ecosystem, and luckily theirs is.
However, as the noble Viscount has pointed out, chalk streams are extremely vulnerable. In fact, the amendment should not be necessary at all because we should automatically be protecting the health and well-being of our chalk streams. So I very much support the amendment. I hope it comes back again and again and we vote on it—or perhaps the Minister will snap it up as a good thing to do.
