I am delighted to follow my right hon. Friend the Member for Leeds Central (Hilary Benn) and the hon. Member for Brighton, Pavilion (Caroline Lucas), whom I congratulate on securing the debate.
Here is my perspective. Life on this planet has been going for 4.5 billion years—4,500 million years. Human beings have been on this planet for 6 million years. That means that we have been around for 0.013% of the time that life has existed on this planet. We are cashing in 4.5 billion years of planetary saving bonds and blowing it on bling, and nothing but our own hubris gives us the right to do so. Exponential growth within a finite system leads to collapse, and that is what is happening—collapse. We know it is happening. Only last weekend, as I was in Durham, the IPBES report set out again what we already know: the global rate of species extinction is between 10 to 100 times higher than the average rate over the past 10 million years. We are living in the Anthropocene—the sixth great extinction event. Human activity is actually being compared to the asteroid that obliterated the dinosaurs—except that unlike the asteroid we know what we are doing. We know that 12% of tree species and over 1,300 wild mammal species are threatened by unsustainable logging and hunting, more than 25% of the world’s forests are subject to industrial logging, and 34% of marine wild fish stocks are overfished—but the plunder goes on.
We politicians are strange creatures: we say we want to do the right thing but so often we end up doing the easy thing instead. We spend our lives trying to win, but in this struggle between ourselves and our planet, there is always going to be just one winner: planet Earth will continue in a new form long after we have made it impossible for our own species to live on it. Reversing the trend of biodiversity loss requires urgent, transformative change. That is code for saying that we need to consume less, because at the current rate of consumption, we would need three planets-worth of resources by 2050. That means that we must examine our economy. It is not just about reducing our consumption; it is about changing our economic accounting model in order to account properly for the free goods and services that we are destroying. Pollination services, clean air, the purification of water by forests and the protection of coastal cities by mangroves are all regarded as externalities by classical economics.
Let me now enter into the earlier debate between the hon. Member for Brighton, Pavilion—my hon. Friend on this side—and the right hon. Member for Epsom and Ewell (Chris Grayling), whom, certainly in terms of conservation, I am happy to call an hon. Friend on the other side. Our obsession with GDP suggests that the coastal surge that destroyed cities such as New Orleans—under hurricane Katrina—resulted in the growth of GDP owing to the economic activity when all the new levees were built. The disaster that destroyed so many
lives and so much wealth is counted in our economic system, GDP, as a positive, but the loss of the tupelo and cypress forest swamp, which had previously—when the trees were not being taken down—reduced the surge swell and protected the city, was not counted as a negative in any economic calculation.
The Dasgupta review, to which my right hon. Friend the Member for Leeds Central referred, set out with great economic force the consequences of what Professor Dasgupta termed “impact inequality”: the imbalance between humanity’s demand and nature’s supply, and the need to reconstruct economics so that nature is an essential part of it and ecosystem services are properly valued. It was disappointing that when the then Exchequer Secretary to the Treasury, the hon. Member for Saffron Walden (Kemi Badenoch), appeared before the Environmental Audit Committee to discuss the Dasgupta review, it became clear that she had not read it. Yesterday, when the chair of the Committee on Climate Change appeared before the Environment, Food and Rural Affairs Committee and was asked about DEFRA’s plan for net zero, it was notable that he said not only that there was no clarity for others, but that there was no implementation that it was possible to judge because the metrics were not there. Just as the Government should implement net zero stress tests for all budgets, so they should implement net nature tests against all expenditure to ensure that alignment with our post-2030 biodiversity framework is maintained.
That brings me to the importance of data. We are extraordinarily blessed in this country to have more than 250 years of amateur scientific data-gathering. We have baselines against which we can say, with real confidence, that 41% of all UK species have declined in the past 52 years, since 1970, but under-employed Church of England vicars and other gentlefolk going back to Georgian England provide us with a database that other countries can only of dream of. May I ask the Minister to ensure that our support for COP15, and the financial assistance that we make available to countries, focus on enabling them to have an accurate dataset of their own natural and biological assets.
