We look at the new breed of investors who are making substantial and sustainable profits by going longterm and investing in keeping ecosystems healthy. We uncover the ultra-slick carbon trading market which is predicted to be worth $300 billion a year before the end of the decade, the multi-million dollar trade in endangered wetlands and how investment banks are buying entire islands and rainforests to make huge future profits. Saving the planet is no longer just about ethics – it’s becoming big business.
