Nicolas Gilsoul takes us on a journey around the world to meet the animals and plants that are populating, sharing, and changing our urban spaces. He introduces us to migratory Mexican butterflies and their relationship with goldenrods; songbirds in the vertical forests of Singapore; and baboons who improvise as winemakers in South Africa. Chlorophyll & City Creatures welcomes our new neighbors and shows how plants can be both friend and foe, ally and enemy, healers and destroyers. Plants are taking over our cities, which are getting greener, proving once more that humans and animals are not the only ones who can live in a concrete jungle.
