Are profits and sustainability compatible?This book brings unique perspectives to this key debate by exploring the history of green entrepreneurship since the nineteenth century, and its spread globally in industries including renewable energy, organic food, natural beauty, ecotourism, recycling, architecture, and finance. The book uses the lens of the extraordinary and often eccentric men and women who defied convention and imagined that business could help save the planet, rather than consume it. The social and religious beliefs that drove many of these individuals are explored as the book looks at how they overcame huge obstacles to execute their strategies. The green entrepreneurs seen here are shown to have created new markets and industries, and driven innovations in sustainable practices, even at timeswhen most consumers and governments marginalized the entire subject. The struggles of early pioneers appear to have been rewarded by the growth of environmental awareness among consumers, business leaders, and others in recent years, but the Earth’s environmental health continues to deteriorate. Ifprofits and sustainability have proved challenging to reconcile, the book argues that one reason was how they were both defined.
