The living world is being hit by everything at once: the only way to stop our full-spectrum assault on Earth systems is to reduce our economic activity.
There is a box labelled “climate”, in which politicians discuss the climate crisis. There is a box named “biodiversity”, in which they discuss the biodiversity crisis. There are plenty of other boxes, such as pollution, deforestation, overfishing and soil loss, gathering dust in our planet’s lost property department.
But all these boxes contain aspects of one crisis, that we have divided up to make it comprehensible. The categories the human brain creates to make sense of its surroundings are not, as Immanuel Kant observed, the Thing-in-Itself. They describe perceptual artefacts, rather than the world.
Nature recognises no such divisions. As Earth systems are assaulted by everything at once, each source of stress compounds the others.
Take the situation of the North Atlantic Right Whale, whose population recovered a little when whaling ceased, but is now slumping again: only 95 remaining females of breeding age remain. The immediate causes of this decline are mostly deaths and injuries when the whales are hit by ships or tangled in fishing gear. But they’ve become more vulnerable to these impacts because they’ve had to shift along the eastern seaboard of North America, into busy waters.
Their main prey, a small swimming crustacean called Calanus finmarchicus, is moving north at the rate of 8km a year, because the sea is heating. As climate breakdown continues, its population in the region is likely to decline by around a third by the end of the century. At the same time, a commercial fishing industry has developed, exploiting Calanus for the fish oil supplements falsely believed to be beneficial to our health. There’s been no attempt to assess the likely impacts. We also have no idea what the impact of ocean acidification – also caused by rising carbon dioxide levels – might be on Calanus and many other crucial species.
As the death rate of right whales rises, their birthrate falls. Why? Perhaps because of the pollutants accumulating in their bodies, some of which are likely to reduce fertility. Or because of ocean noise from boat engines, sonar and oil and gas exploration, which stresses them and disrupts their communication. So you could call the decline of this species a shipping crisis, or a fishing crisis, or a climate crisis, or an acidification crisis, or a pollution crisis, or a noise crisis. But it is in fact all of these things: a general crisis caused by human activity.
Or look at moths in the United Kingdom. We know they are being harmed by pesticides. But the impact of these toxins on moths has been researched, as far as I can discover, only individually. Studies of bees show that when pesticides are combined, their effects are synergistic: in other words the damage they each cause isn’t added, but multiplied. When pesticides are combined with fungicides and herbicides, the effects are multiplied again.
Simultaneously, moth caterpillars are losing their food plants, thanks to fertilisers and habitat destruction. Climate chaos has also knocked their reproductive cycle out of syncwith the opening of the flowers on which the adults depend. Now we discover that light pollution also has devastating effects on their breeding success. The switch from orange sodium streetlights to white LEDs saves energy, but their wider colour spectrum turns out to be disastrous for insects. Light pollution is spreading rapidly, even around protected areas, affecting animals almost everywhere.
Combined impacts are laying waste to entire living systems. When coral reefs are weakened by the fishing industry, pollution and the bleaching caused by global heating, they are less able to withstand the extreme climate events, such as tropical cyclones, that our fossil fuel emissions have also intensified. When rainforests are fragmented by timber cutting and cattle ranching, and ravaged by imported tree diseases, they become more vulnerable to the droughts and fires caused by climate breakdown.
What would we see if we broke down our conceptual barriers? We would see a full spectrum assault on the living world. Scarcely anywhere is now safe from this sustained assault. A recent scientific paper estimates that only 3% of the Earth’s land surface should now be considered “ecologically intact”.
The various impacts have a common cause: the sheer volume of economic activity. We are doing too much of almost everything, and the world’s living systems cannot bear it. But our failure to see the whole ensures that we fail to address this crisis systemically and effectively.
When we box up this predicament, our efforts to solve one aspect of the crisis exacerbate another. For example, if we were to build sufficient direct air capture machines to make a major difference to atmospheric carbon concentrations, this would demand a massive new wave of mining and processing, to make the steel and concrete. The impact of such construction pulses travels around the world. To take just one component, the mining of sand, mostly to make concrete and asphalt, is trashing hundreds of precious habitats. It’s especially devastating to rivers, whose sand is highly sought in construction. Rivers are already being hit by drought, the disappearance of mountain ice and snow, our extraction of water and pollution from farming, sewage and industry. Sand dredging, on top of these assaults, could be a final, fatal blow.
Or look at the materials required for the electronics revolution that will, apparently, save us from climate breakdown. Already, mining and processing the minerals required for magnets and batteries is laying waste to habitats and causing new pollution crises. Now, as Jonathan Watts’s terrifying article in the Guardian this week shows, companies are using the climate crisis as justification for extracting minerals from the deep ocean floor, long before we have any idea of what the impacts might be.
This isn’t, in itself, an argument against direct air capture machines or other “green” technologies. But if they have to keep pace with an ever-growing volume of economic activity, and if the growth of this activity is justified by the existence of those machines, the net result will be ever greater harm to the living world.
But everywhere, governments seek to ramp up the economic load, talking of “unleashing our potential” and “supercharging our economy”. Boris Johnson insists that “a global recovery from the pandemic must be rooted in green growth”. But there is no such thing as green growth. Growth is wiping the green from the Earth.
We have no hope of emerging from this full-spectrum crisis unless we ramp down economic activity. Wealth must be distributed – a constrained world cannot afford the rich– but it must also be reduced. Sustaining our life-support systems means doing less of almost everything. But this notion – which should be central to a new, environmental ethics – is secular blasphemy.

“there is no such thing as green growth. Growth is wiping the green from the Earth.” Conundrum on top of conundrum. I will share this. Thank you.
