What if you were told that one solution to crises such as global warming and the worldwide financial meltdown could be unearthed in the simple act of growing your own food? Nothing drastic; nothing revolutionary. Just a window box for a tomato plant in your kitchen."It's remarkable, but people who grow their own food, who reconnect with the soil, can immediately appreciate the implications of an economy that doesn't respect the power of ecology," says Woody Tasch, somewhat quixotically. But Tasch is no quack. He's chairman of the Investors' Circle, a national group focused on funding socially responsible companies. Since 1992, Investors' Circle has placed $130 million into 200 such businesses and venture funds.
