In this powerful and practical new book, Gregory Schwartz combines two decades of academic research with the adventures and local wisdom garnered from visiting nearly forty countries in order to provide answers to some of the world's most pressing questions. For example, the solutions to our biggest environmental and social problems already exist, so why are we not choosing to act on them? Whether it's benefiting the environment, your health, or the least fortunate among us, you'll learn how to make an immediate and global-scale impact with a few simple actions that easily fit into your daily routine.
