In this book, scientists who are pre-eminent in their fields focus on the crucial role of science in the transition away from a culture of war towards the construction of peace based on a capacity to anticipate and prevent destructive conflicts. The subject matter, wide-ranging and of great concern to people everywhere, includes the progress and prospects for a nuclear-weapon-free world; non-nuclear threats to peace and security; the building of legitimate world institutions; conflict resolution and the construction of peace; the local and global environmental dimensions of peace; the health hazards of nuclear chemical and biological weapons; and the interactions between health problems and poverty.
