On grand scale -- it's possible. But try to live in harmony in a shared space with a wild fox or a wolf. Not good for you, not for the sentient creatures.
Not everything is perfect. I am not "kill nothing." But I try very hard to live well with nature by trying to understand it.
And its good for all of us.
London foxes are used to people.
When I'm walking home very late at night (urban area) I'll often pass one or two. They're just... there.
I live in harmony near lots of wild things, including some foxes. They stay on the outside of my house and I stay on the inside. It's not "perfect" but it works pretty well.
