If you live in a city then you need to read this book.
Cities have become the locomotives of pollution. City spread generates commuting which in itself is a giant factor in CO2 emissions.
Add in the largely fossil fuel based energy consumption from heating and air-conditioning and you have a all the ingredients of a disaster.
When the added impact of city life in human terms is taken into account, then it becomes obvious that a new way has to be found.
This book is about how we start to fix it all — starting with changing the cities that we do have into compact cities.
