Sustainability will help us educate our children (and ourselves) about the needs of our land for the future, primarily these days by getting involved in programs to help the bees and butterflies survive. In so doing, we also protect our own survival as a species. This may seem surprising, but its true. Entomologist Doug Tallamy at the University of Delaware has stepped out boldly to tell us that the benefit of diversity at the bottom of the food chain — among insects and birds — flows upward and has a direct effect on human life and health. His website is worth a look! What he’s telling us is important because in just the last 40 years we have lost half of the songbird species, and though the bee population is beginning to stabilize, we still have a long way to go.
