In a world that needs to get past its view of human beings as the centre of everything, the city can no longer take just the interests of people into account. Our health as citizens depends on the trees that clean the air we breathe and on the vitality of our microbiome. Our quality of life is directly related to that of the birds nesting in our environment. Every city today is an ecosystem with delicate balances and a multi-species community.

The Covid-19 crisis has made us all the more aware that the destiny of humans is intertwined with that of all the other species on the planet. The double threat to the planet from the climate crisis and the biodiversity crisis obliges us today to think of urban planning from new paradigms that reconcile the well-being of humans with that of our neighbouring species in the city. And even, of course, to carry out architectural projects to meet the needs of non-human inhabitants in the city.
