TAURUS (April 20-May 20): The world’s largest private bank, Citigroup, has agreed to stop financing projects that damage sensitive ecosystems. It has promised to invest more in projects that use renewable energy and to pursue policies that protect indigenous people. How did this impossible dream come to pass? The humble but dogged environmental group, Rainforest Action Network, creatively pestered Citigroup for years until the corporation gave into its demands. I see a comparable David-over-Goliath victory in your future, Taurus, so keep plugging away at your quixotic quest. For inspiration, recall Margaret Mead’s words: “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it’s the only thing that ever has.”
