This book is for everyone who loves cities but hates concrete jungles! From private space to public space, from your home to the entire city, find out about 50 practical, active and activist ways to make your surroundings greener. Every little step counts! Start slowly at home, then try out more ambitious experiments outside: build your own worm compost, collect your own seeds, set up a rainwater recovery system and beehives on the rooftop, hijack urban furniture, throw seed bombs, vanish that concrete, found a community garden, and more!
