When I think of a food chain, I always picture a giant whale swimming through the ocean gobbling up smaller sea creatures in his path. But food chains are part of a broader ecosystem, and, as humans, our place at the top carries awesome responsibility. Sure, we could go through our lives eating whatever suits our fancy, but doing so without a thought to future generations would be reckless. Here on Nourish Network, there has been much written about sustainability, and at its core, that’s what eating lower on the food chain is intended to promote: sustainable food systems that take the long view rather than satisfying our immediate cravings. With Earth Day upon us, the time is right to consider how eating lower on the food chain benefits not only us, but the planet at large.
