Commons ChamberI congratulate the hon. Member for Brighton, Pavilion (Caroline Lucas) on securing the debate and on making such a terrific speech. As she said, the forthcoming COP matters enormously for all the reasons she set out. We need targets so we can measure progress—that is the great benefit of them—and we need funding to help make that progress. We need every country that makes a commitment to have a plan back home to deliver it. We need progress to be measured and above all we need leadership. We need leadership internationally, leadership domestically in communities and leadership by us as individuals.
The decline in biodiversity and the loss of species across the world is well documented, but sadly not well known enough. I should declare my interest, as one or two other Members have, as the water vole species champion. That is an extremely grand title, especially when it is held by someone who, despite his best efforts, has yet to see a water vole in the wild. I did once hear the characteristic plop sound that water voles make—I know Ratty well from reading “The Wind in the Willows” to my grandchildren—when they come out of their mud tunnels in the riverbank and drop into the water. Perhaps it is very hard to see them for the very simple reason that since the end of the 1990s, a nationwide survey showed that water voles had disappeared from 90% of the sites where they were found a decade before—90%! There has been a further decline in the decade thereafter. In the case of water voles, one particular problem is predation by mink, who need to be controlled. What is really needed, however, is to improve water quality and to encourage farmers to restore and protect healthy waterways—in other words, places and rivers where water voles can thrive.
The heart of the problem we must address—colleagues touched on this in their contributions—is that we as humankind have been making use of the earth’s gifts, those on the land and those beneath the seas that surround us, as if there was no consequence and no end to nature’s bounty. That is what we have been doing and the pace at which we have done that has accelerated enormously in the last century or so. Just as with the climate crisis, we know now that that is not true: there is a limit and we have to start taking proper care, because we rely on the natural world and biodiversity for our very existence, including our economic welfare. We should applaud the work of Pavan Sukhdev—I had the privilege to meet him when I was the Environment Secretary—and Sir Partha Dasgupta, who have taught us about the economic value of biodiversity, if we wish to measure it in that way, just as Nick Stern told us about the far greater cost of not dealing with dangerous climate change, as opposed to the far lower cost of dealing with it, saying, “You make the choice.”
As we know, the natural world provides us with the very essentials of life: clean air and water, and food and fuel. It regulates our climate and helps to deal with pollution. It stems floodwaters and produces medicines. It is the very foundation of our economic and social wellbeing. A few years ago, I had the honour and privilege to visit the World Agroforestry Centre in Nairobi. We went into a lab and there was a range of plants on a bench. I went along, asking “What’s this? What’s this?” One was a small artemisia sapling and another rather odd-looking bit of bark apparently came from the prunus africana tree. I happened to know, because of my job, that artemisia is essential to making combination anti-malarial drugs more effective. I learned that pygeum—I do not know if I have pronounced that correctly—from the bark of the prunus africana tree has properties that help to treat prostate cancer.
We stood there discussing malaria, which is predominantly a disease of the poorer world, and prostate cancer, which has been a disease predominantly of the better off world, although that is beginning to change. We rely on both those plants to treat those diseases. Let us imagine that some clod-hopping human being millions of years ago had walked through the forest and decided to pull up to examine the only artemisia sapling and the only prunus africana sapling on the planet—think what we would have lost. That is why there is such a strong argument for looking after both what we have and know about and the plants that surround us of which we have not yet discovered the properties.
Despite the gravity of the crisis in biodiversity, it is important to try to address the task with optimism, because in the end, making ourselves depressed about the scale of the challenge is not, in my experience, a great motivator for action. We know that we can make progress. We can look at the creation of the national parks: that extraordinary bit of legislation from the post-war Labour Government came out of a time of great conflict, economic crisis, debt and so on, with the support of politicians right across the House who were legislating to preserve beauty for posterity.
We can look at the size and commitment of the wildlife trusts. They have about 870,000 members, look after 2,300 nature reserves and provide some of the connections that my right hon. Friend the Member for Islington North (Jeremy Corbyn), who spoke so well, was talking about. Bits can be looked after, but the connection between them will help us truly to restore nature, which is why, towards the end of my time as the Environment Secretary, I asked Sir John Lawton to produce a report precisely on how those connections can better be made.
We can look at the marine conservation zones, which were created thanks to the Marine and Coastal Access Act 2009.
My right hon. Friend’s point about connectivity is very important. Is he aware of the agreement between a number of central American countries to create a wildlife corridor for the jaguar to survive, because it travels over a huge range? If it is cut off in certain isolated bits, it will simply die off.
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.
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?
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.
I apologise for popping out briefly for a family call. Last summer, I went to the far north of Scotland. The further north we got, the more insects hit the windscreen. As more arable farming happens in the south of the country than in the north, that seems pretty clear evidence of the link between the disappearance of insects and pesticides. That is one reason why I was so attracted by the regenerative farming model.
I agree completely. There are one or two insects in the north of Scotland—midges in particular—that can cause a certain amount of distress, but just think of the glory of the Scottish countryside and the mountains. Who does not feel a sense of awe and wonder as they contemplate the astonishing biodiversity and landscape that our small islands reveal unto us?
I commend the right hon. Gentleman for the planting that he has done on his acres of land. He spoke about the changes that he has seen. I am fortunate to live on a farm, where we have had the opportunity to plant trees directly. We have planted some 3,500 trees, retained the hedgerows and put in two ponds. We regularly see bees, moss and lots of wildlife. The Government have committed to replanting across the whole United Kingdom. Does the right hon. Gentleman feel that there should be more of a commitment to tree planting, to ensure that we can become the lungs of the world?
I agree completely. There should be no limit to the number of trees that we can plant. We can each play our part if we have the opportunity. As MPs, because of the nature of our job, we probably get invited to plant the odd tree in our constituencies.
The point that the right hon. Member for Islington North made about front gardens is really important. One of the things we did after the floods of 2007 was to change the planning rules. People cannot hard pave over their front gardens any more unless they use permeable paving, because if we pave, tarmac and concrete over all the land in a town or city and huge quantities of rain fall out of the sky, of course the water is going to flood into people’s homes. That makes us realise the inter- connection between our choices as human beings and the consequences of not paying sufficient attention to nature.
I would argue that to be disconnected from nature is to be disconnected from the Earth itself, so it is not just self-preservation that should urge us to confront the threat of climate change and biodiversity loss, which are absolutely connected, but our love for the soil from which we all came and to which one day we will all return—but not just yet.
