For some of Britain's most powerful people, hunting and shooting are primordial rights, and any challenge to them is treated as illegitimate. They assert ownership not only of the land but also of the social relationships surrounding it.

Until fishing is properly regulated and contained, we should withdraw our consent. Save your plastic bags by all means, but if you really want to make a difference, stop eating fish.

The high seas - in other words, the oceans beyond the 200-mile national limits - are a lawless realm.

I want to be represented by people who are thoughtful, self-aware and collaborative. What would a system that elevated such people look like?

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.

For some people, it is easier to command a nation, to send thousands to their deaths in unnecessary wars, to separate children from their families and inflict terrible suffering, than to process their own trauma and pain.

In politics, almost everywhere we see what looks like the externalisation of psychic wounds or deficits.

There is plenty of housing - for the rich. But a series of outrageous policies ensure that it remains inaccessible to the poor.

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.

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.

While some livestock farms are much better than others, there are none in this country that look like natural ecosystems. Nature has no fences.

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.

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.

It doesn't matter how many solar panels you install if you don't simultaneously shut down coal and gas burners.

We should continue to mobilise against the destruction of the world's great habitats, and its terrifying implications. But the most persuasive argument we can make is to show we mean it, by restoring our own lost wonders.

We urgently need more trees, but we appear to believe that the only means of restoring them is planting. We have a national obsession with tree planting, which is in danger of becoming as tokenistic as bamboo toothbrushes and cotton tote bags.

I could see the point of Brexit if it meant returning power to the people.

When expressions of emotion are dangerous, and when you are constantly told that this terrible thing is being done for your own good, you quickly learn to hide your true feelings, even from yourself.

The justification for early boarding is based on a massive but common misconception. Because physical hardship in childhood makes you physically tough, the founders of the system believed that emotional hardship must make you emotionally tough. It does the opposite.

We are often told that curtailing the freedom of business is coercive and undemocratic. But by what democratic principle should corporations and billionaires decide the fate of current and future generations? When a government releases them from regulation, it allows them to determine whether other people live or die.

If we stop dragging trawls and dredges through it, the life of the seas would recover with astonishing speed. Because most marine animals are highly mobile during at least one stage of their development, the rewilding of the seas needs little help from humans.

When I kayak in Cardigan Bay, in Wales, what I hope to find above all else is dolphins. Sometimes I do, and these days are the waymarks of my life.

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.

Farmfree production promises a far more stable and reliable food supply that can be grown anywhere, even in countries without farmland. It could be crucial to ending world hunger.
