the fish and the seabirds had enough to feed on; if fishing were managed for the long term; and if the cold-water corals and the underwater wonders were allowed to return to where they were before fish farms polluted them and trawling and dredging scoured them away. Imagine if there were no longer any need for Surfers Against Sewage, and it was no longer possible to see the algae plume from the Thames right out into the North Sea (joining the plume from the Rhine).

      It might even be possible to make an economic merit out of cleaning up the beaches. It could be a form of national service, or a task taken on by local communities and local schools. They could take ownership of keeping their patch of the coastline clean, and in the process gain from the community involvement and mental health benefits – as well as the exercise it would involve. Many economic activities are outside the formal measured GDP, but they matter for prosperity.

      Finally, imagine what our towns and cities could be like if we invested in their green infrastructure. Imagine how much healthier and more vibrant they might be. Imagine if every child had access to a green space within a few hundred metres of their home. Imagine if today’s developers actually built houses with proper back gardens. Imagine allotments for many more people, green roofs and green walls, and new and enlarged parks. Imagine if the parks were vibrant healthy environments, with lots of biodiversity, instead of the mown monochrome lawns. Imagine if plants were encouraged alongside railway lines, road verges and urban canals, and trees planted in every street. Imagine if nature’s much more messy beauty replaced the ugliness and sterility that straight lines and tidiness bring.

      Britain’s gardens comprise an area the size of the Norfolk Broads, plus Exmoor, plus Dartmoor, plus the Lake District. Acres of Britain are gardens and they have an enormous potential as wildlife havens.[11] Indeed, they already are: gardens can be much more biodiverse than intensive agricultural land. Imagine if every garden had a small pond and a patch of wild flowers, besides the conventional palette of garden plants, fruits and vegetables. Imagine if all of these were chemical-free. This would be a great refuge for bumblebees and honey bees, lacewings and spotted flycatchers, swallows, frogs, newts and toads, and hedgehogs too. It would also bring many who have nature-deprived lives, and especially children, face to face with the beauty of nature. They might even dig up their concrete driveways and allow water to be absorbed by the ground, reducing flooding and creating sustainable drainage.

      Putting all this together would create much greater genuine prosperity. It would be the right thing to do, because it would be both the economic thing to do and, in the process, would deliver the environment that many environmentalists who reject economic approaches would want too. It would also be ethically right, fulfilling our duty as stewards of the natural environment on behalf of future generations. There would be hen harriers and golden plovers and curlews and flycatchers, and there would be all sorts of plants, insects and other fauna.

      It would not be a wild world, and it certainly would not be a ‘re-wilded’ world. It would be every bit as managed as it is today. Even those areas left aside would be deliberately chosen for intentional neglect. Deer would be culled, hedges would be reinstated and managed, rivers would be built around natural capital deliberately put in place, and city streets would be planted with trees. The prize is not an abandonment of the land to the ‘forces of nature’, but the replacement of a badly managed natural environment with a much better managed one. We have witnessed the disastrous consequences for people of taking the nature out of their lives, and we can redress this, but we cannot take the people out of nature.

      Wouldn’t it be wonderful if this was what we could pass on to the next generation?

       BUSINESS-AS-USUAL

      Imagine waking up in May 2050. You might remember the May mornings before 2020. This was a time of bright yellow oilseed rape fields. There were still some swallows, a few swifts and the occasional cuckoo. In the right place you might have heard a curlew. If you were really lucky you might have seen a spotted flycatcher. In 2050 it will be very different if we go on as we are. By then, all these birds will be rarities. There will be even fewer insects, agriculture will be more intensive and the fields barren of anything but the chosen crop.

      There will be 5 million more houses, and little left of the Green Belt, except perhaps in name. Lots more roads, railway lines, solar panels and wind turbines will have industrialised the countryside. There will be very few wild salmon left, but lots of fish farms and more Trump-style golf courses. Nature will be ever-more confined to reserved areas – like zoos in an increasingly urban and industrial landscape.

      There will be compensations. You will have communications technologies that cannot even be imagined today, just as I have an iPhone now, which was unimaginable a couple of decades ago. Everything will be digital, with robots, 3D printing and artificial intelligence (AI) fulfilling many of your needs. You will know your genome, and have medical treatments available to you that again are hard to imagine now.

      Some economists continue to think that the natural capital you will have lost is a price worth paying for all these new benefits. But much of this can’t be simply substituted, because natural capital is not like that, open to a marginal loss here and a marginal loss there. Nature isn’t marginal, and it does not come in discrete bits to trade off against discrete bits of man-made and human capital. Worse still, it might bite back: you may know your genome, but you might not have any antibiotics that work.

      This is the silent, grey and impoverished natural world we could leave to the next generation. It is what it might look like if we don’t act now, and confront the stark reality that we face if current trends continue. We cannot and should not shy away from thinking through what will happen if we carry on damaging nature and allowing our stock of natural capital to continue to decline. It is not just about the loss of nature, and all the spiritual and emotional underpinnings to what makes us fully human, but about our economic prosperity, which depends on nature and natural capital. The land would be a dull, brown and unprosperous land – and a lot less appealing to share pictures of on whatever replaces Instagram by then. We really would need a virtual and screen-based reality to console ourselves with.

      Being brown, not green, means a lower level of sustainable economic growth, and perhaps even no growth at all. It is against this background that the case for nature is to be seen as a great opportunity to make us all better off: better off in a narrow economic sense, as well as a wider sense. May 2050 could be noisier and more vibrant and exciting than May 2020, and more prosperous too. But not unless we make this happen.

       A damaged inheritance

      The decline of nature in Britain has been extensively documented by some of the world’s best naturalists. There are books about the decline of particular species, and studies and reports on the more general declines of life on farmland, uplands and in the soils. Even where things appear to have got better, as with water and urban air quality, some of this is not what it seems.[1]

      Much of this evidence is specific to particular species and habitats, and it is supplemented by anecdotes and personal memories, and in novels and films. It is a spiritual and aesthetic loss, as well as a scientific one. Laurie Lee’s world of Cider with Rosie in the Slad Valley in Gloucester, Flora Thompson’s Lark Rise to Candleford, and the novels of Thomas Hardy describe a landscape full of colour and variety, with wild flowers, songbirds and elements that could almost be called wild, even though they are all man-made.[2] The early landscape painters and the Romantics eulogised nature and developed concepts of the ideal landscape and the picturesque, and Wordsworth
