Over the past 60 years, the world has seen gradual and hard-won progress in reducing child mortality and improving the lives of opportunities of children. Some of this is attributable to medical science, much of it to simple but effective public health measures. Even though 24,000 children continue to die each day from preventable causes, this represents a dramatic improvement, and progress continues to be made. Climate change threatens to undo all of this progress, and wipe out the gains of decades. The threat of rising sea levels, the potential loss of productive farmland and the potential threat to water supplies are all profound concerns, and threaten the well-being of children and communities around the world. This book examines the connection between climate action and the future of childrens' health.
