With all the goodwill and local initiative in the world, we are not about to rewild anything until we change our way of thinking about our place in the creaturely world.
What is essential - the one thing that could stop us being coarsened to other lives - is that we feel a great, living wave of animal life all around us, covering the earth.
In time, we will have to recognise that it is not 'nature' that we need to protect, but ourselves, and we can only do this by abandoning the old, grandiose, profit-seeking schemes so beloved of our masters and learning to till the soil, live to scale, and live within our means.
I know that the only reason American landscapes sometimes disappoint me is that, just a century before I was born, the great rivers and prairies and wild forests still existed. And they were sublime.
I remember a nightfall from childhood, far from home and off the known track: I'd been walking with some older boys, but they ran off and left me, and as darkness hurried in, I suddenly realised how far from home I was.
Growing up, I learnt to think, 'Let's make it a big night tonight, as you never know what's going to happen next.' So now I have enough, I take too much; when I get the chance to have a fine dinner, I will. And it's had an effect on my health.
The woods were a boon; all too often, the forest offered danger and mystery. Yet it could be liberating. If you entered that wild place on its own terms, you might be accorded wisdom.
Given the right information to help them decide, people will opt for conditions that benefit our creaturely neighbours, even where they have no particular interest in larks or cuckoo wasps - because those conditions benefit us.
Usually, I would mistrust a book if it took that long to write. Usually, if it isn't done in two years, I suspect there's something wrong and throw it away.
It may be a cliche, but cliche or not, I fear the day when the only marsh harriers or peregrines I can look at are in paintings by Joseph Wolf or Bruno Liljefors - and no matter how beautiful those works may be, life is the great thing: life, life, life.
With fiction, I tend to get to my desk and start writing. Poetry I write in my head, often while walking, so that my poems have an organic quality, hopefully.
I remember when I first encountered anthropocentrism. I was in primary school and, in preparation for our confirmation, the class was learning about the afterlife.
When you have a child, you think about your personal history and what you offer them as a larger narrative, and I realised I knew nothing about my father's circumstances other than what he'd told me.
The Botanischer Garten in Berlin has one of Europe's finer winter trails, leading in careful order from glasshouses devoted to African-American and Australian desert species, through a fine collection of tropical plants, and on to the orchid house.
People will occasionally ask me if I understand what it's like to be lonely. And the truth is I don't, because for me, solitariness is a blessing, a gift. Me, I get on fine with myself.
