Twenty-first-century minimalism is an increasingly mainstream response to global environmental crises such as climate change, the garbage glut, fast fashion, and other manifestations of the harmful impact of consumerism. Originally founded in the art world in the decades after World War II, minimalism has evolved into an Earth-friendly lifestyle focusing on the three Rs (reducing, recycling, and reusing) and on simplifying individual needs to reduce one's carbon imprint, manage anxiety and depression, and prioritize human interaction over the impulse to acquire for the sake of acquisition. Hands-on activities, how-to tips, and profiles of practicing minimalists offer real-world examples for incorporating minimalism into your life.
