Diane MacEachern’s “Big Green Purse” In this lively and educational book, Diane MacEachern makes the case that organizing the world’s most potent consumer force—women—is the most effective strategy for combating companies that contribute to environmental degradation. She exhorts women to make deliberate use of their purchasing power by allocating their funds to goods that will have the biggest positive impact on the environment. The book focuses on twenty goods where women’s spending can have a significant impact, including food, paper goods, cars, cosmetics, and coffee. It breaks down products that are labeled as “eco-friendly” from those that are truly “green,” offers simple-to-follow rules, and suggests businesses to support.
