Protecting and Restoring Nature: COP15 and Beyond — House of Commons, 2022-07-14
Topic: Environment
Hilary James Benn (Labour, Centre-left): I 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.
