The five horsemen of the modern world : climate, food, water, disease, and obesity / Daniel Callahan.

Our overheating, fraying planet
Feeding a growing population : how, and with what kind of food?
Water : not everywhere and not always fit to drink
Chronic illness : rich or poor, few escape
Obesity : the scourge of bad diets and sedentary habits
Always more people and ever more elderly : caring and paying
The technology fix : a way out?
A volatile mix : public policy, the media, and public opinion
Law and governance : managing our public planet and our private bodies
Progress and its errant children : more is never enough
The necessary coalition : social movements, legislatures, and business.
