Protecting and Restoring Nature: COP15 and Beyond

Debate between Hilary Benn and Kerry McCarthy

Thursday 14th July 2022 Commons Chamber

[Hilary Benn]

I was not aware of that—I am now—and what a great idea for countries to work together in that way.

When we were taking the Bill that became the 2009 Act through Parliament, I was really quite surprised to discover how little we appeared to know about what was on the seabed surrounding these islands. Some very intrepid divers, some of whom I met, went down and took photographs. If the photos were shown to me or to anybody else and the question was asked, “Where was that picture taken?”, most people would say, “Is that the Great Barrier Reef?” No—it was under the murky waters of the North sea.

One thing we know about nature is that although we have been destroying it at a rate of knots, if we give it the chance, it can recover with astonishing speed. The North sea was originally covered abundantly in oyster beds, coarse peat banks and rock deposited by glaciers, and it was home to a rich community of marine species. A lot of that was sadly destroyed by bottom-trawl fisheries over the past century and it is now a relatively poor community of species.

Let me say a word on bottom trawling. It is an incredibly destructive practice, but it is unseen because it takes place beneath the waves. To make a slightly absurd analogy, let us imagine that to collect apples, someone decided to drag a net across the countryside taking with it all the hedges, tree saplings, bird nests and the trees on which the apples hang just for the purpose of collecting the apples in the process. People would be outraged and appalled, but that is what we have been doing on the surface of the seabed for a long time and no one sees it happening. It is about bearing witness to what is going on. The right hon. Member for Epsom and Ewell (Chris Grayling), who is not in his place, talked about the deforestation of the Amazon. The thing about technology is that, with satellites, we can see how the rainforest is reducing over time. It is really important that we use all those means to bear witness to what is taking place in order to motivate change.



We find the recovery of nature in some surprising places. There has been a lot of debate about the impact of wind farms on birds, but research has shown that, in effect, wind farms act as artificial reefs. They can host a very wide range of marine species once nature has had a chance to recover.

My final point is about the contribution that nature makes to our health and wellbeing.

[Kerry McCarthy (Bristol East) (Lab)]

I am sorry that I could not be here for the beginning of the debate. Is there not a concern that although many marine protected areas have been designated, they are really just paper parks because things like bottom trawling are being allowed to continue? Does my right hon. Friend also share my concern that there is now a move towards deep-sea mining, which could be hugely environmentally damaging?

[Hilary Benn]

Yes, I do. There was cross-party support in the House of Commons for the Marine and Coastal Access Act 2009 and the creation of marine conservation zones. We basically have a planning framework; we have had one on land for a long time, but we did not have one for the sea at all. We are now confronted with a choice about what we permit. The ability to understand the consequences of what is happening beneath the waves is important. We now have the means to do something about it, but we cannot just say “We’ve got the designation —job done,” and move on to something else. That is not sufficient at all.

Yesterday, my wife and I were discussing what I might talk about in this speech. Apart from telling me, “You must mention the water voles,”—I have now duly done so, and I hope that she has noticed—she said, “Tell them about our oak trees.” For the past 30 years or so, we have been planting oak trees from seed, along with ash and silver birch trees. “Nature reserve” would be a very grand title for the eight acres of former farmland in Essex that my mother set aside, where nature has been left to do its work. The tallest oak tree is probably about 20 or 25 feet now. Over the years, the trees that we have planted—the trees that nature has brought—have brought with them cuckoos, owls, adders, foxes, muntjac deer, the odd badger and white campion, as well as loads of brambles that I attempt to do battle with whenever I can. Every time I walk on that piece of land, I feel the same sense of anticipation about what has changed, what has grown and what is different.

Why do we feel like this? Because nature is part of our very soul. It is about who we are and where we come from. Think of how we encounter it—looking out of the window of a train as it rushes through the countryside, seeing the first crocus of spring, encountering the wonders and glories of the Yorkshire dales, seeing a view of Ditchling Beacon or a view of Scafell Pike from Great Moss, or hearing the buzz of a bee at the height of summer. We do not hear that buzz as much as we used to, or see as many moths. I remember when moths were really common in the summer. When did I last see one? There was an extraordinary experiment in which people were asked to put a bit of sticky plastic on their number plate, drive around and count how many insects were caught. That showed that there has been a catastrophic decline.
