In 1993, the Prize went to Professor Paul R. Ehrlich of Stanford University and Professor John P. Holdren of the University of California in Berkeley, whose work laid the foundations of our understanding of how the dynamics of population growth, rising living standards and changing technology, as well as the relationships between them, interact in the context of environmental problems.
