Cities are both in the front line of increasingly extreme weather events such as heatwaves and floods, and major sources of the pollution that pushes climate breakdown. But green a city, and you help to make it more climate-proof and take the pressure off global warming. Once steps are taken to green cities, a host of other benefits emerge. The air becomes cleaner, reducing childhood asthma and a host of other lethal health complaints directly linked to dirty air. By involving a wide range of people in the process, cities can benefit from their knowledge and ideas to make greener cities work for everyone.
Shifting away from the dominance of polluting, private cars toward clean mass-transit systems makes our streets and neighbourhoods safer places to play, and more peaceful for all residents. Living streets bring communities together too. Urban growing can rebuild a relationship between people and real food, make a shift to better diets easier, and also bring people together.
