Often poorly governed, their conditions produce millions of preventable deaths and extensive disease. This book describes these cities' environmental problems and how they affect health, local ecosystems and global cycles. It analyzes the causes: the failure of governments to supply clean water and implement existing measures, or land-owning structures that marginalize the poor. It also highlights the innovative ways in which problems are being tackled, showing solutions are available and the action needed by cities, local governments and community organizations.
