"It won't take you long to read this book, but it will linger in your heart and head for quite a while, and perhaps inspire you to join in the creative, blossoming movement to make this world work." -- Bill McKibben Pocket Change Collective is a series of small books with big ideas from today's leading activists and artists. In this installment, Earth Guardians Youth Director and hip-hop artist Xiuhtezcatl Martinez shows us how his music feeds his environmental activism and vice versa. Martinez visualizes a future that allows us to direct our anger, fear, and passion toward creating change. Because, at the end of the day, we all have a part to play.
