If we want to prevent both climate and ecological catastrophes, the key task is to minimise the amount of land we use to feed ourselves, while changing the way the remaining land is farmed. Instead, governments almost everywhere pour public money into planetary destruction.
Brexit, for all its likely harms, represents an opportunity to pay landowners and tenants to do something completely different, rather than spending yet more public money on trashing our life-support systems.
I believe that anyone who wants to stand in a national election should receive a course of psychotherapy. Completing the course should be a qualification for office. This wouldn't change the behaviour of psychopaths, but it might prevent some people who exercise power from imposing their own deep wounds on others.
While some people have rejected capitalism gladly and swiftly, I've done so slowly and reluctantly. Part of the reason was that I could see no clear alternative: unlike some anti-capitalists, I have never been an enthusiast for state communism.
I might find myself standing, transfixed, by the roadside, watching a sparrowhawk hunting among the bushes, astonished that other people could ignore it. But they might just as well be wondering how I could have failed to notice the new V6 Pentastar Sahara that just drove past.
As Dutch elm disease spread across Britain in the 1970s, the country fell into mourning. When the sentinel trees that framed our horizons were felled, their loss was a constant topic of sad and angry conversation.
Farming and fishing are the major causes of the collapse of both marine and terrestrial ecosystems. Meat - consumed in greater quantities by the rich than by the poor - is the strongest cause of all.
Places that have become agricultural deserts, trashed by giant corporations, could be reforested, drawing carbon dioxide from the air on a vast scale. The ecosystems of land and sea could recover, not just in pockets but across great tracts of the planet.
Rather than allowing Roma, Travellers and homeless people to be picked off, all those of us who fear the criminalisation of trespass should join forces with them, protecting their rights while we defend our own.
Wildlife film-makers I know tell me that the effort to portray what looks like an untouched ecosystem becomes harder every year. They have to choose their camera angles ever more carefully to exclude the evidence of destruction, travel further to find the Edens they depict.
There's nothing good about ash dieback, but there is one useful thing that could be done: wherever possible, leave the dead trees to stand. There is more life in a dead tree than in a living tree: around 2,000 animal species in the UK rely on dead or dying wood for their survival.
I have tried to keep my eco-anxiety at bay, to box it into my working life. But every month this becomes more difficult. The rising sense of panic I feel is entirely rational; we should all be feeling it. But we can't live with it through every hour of every day.
