Cities are ecosystems. They have been for at least four thousand years. They are the ecosystem we inhabit but neglect… the ones where our children are raised. Maybe you live in the country. I used to, but life in the country is increasingly the global minority. We have moved to the city and now we must make it, ecologically speaking, a reasonable place to live. I have spent the last five months moving across Europe from one city after another, sometimes delighted, other times angry. As someone who studies the species in cities, the wild and wonderful species, and has spent the last three years immersed in the stories of these species and how they benefit or cost us (whether in being present or absent), I have a few thoughts, notes to myself for when I go home on what, from the perspective of our health and well being and that of other species, we might need to do. Maybe you will also find them useful.
