Critical Mass: Transport, Environment and Society in the 21st CenturyPluto Press, 20 sept. 1997 - 251 pages Despite demanding enormous resources, transport policies are incapable of resolving basic problems of safety, health, welfare and congestion. This book, pointing out that car-dependency is shared throughout Europe, Asia and North America, argues that the problems can only be solved globally by a shared recognition of common needs. In addition, with transport inextricabley linked with consumerism and the lifestyles that car ownership has created, the book argues that the challenge is to replace the current technology with an alternative that is sustainable and will solve the fundamental problems of poverty, inequity and social development. |
