Here's a secret climate-change activists and energy-efficiency and renewable-energy promoters neglect: Nature is designed to be self-healing, and her most profound 'tool' is photosynthesis. 'Free' sunlight is the best energy source to extract carbon dioxide from the atmosphere, while also producing organic matter and oxygen--and a by-product is healthier soil, forests, wetlands, and ecosystems. When politicians, policy leaders, and activists get serious about cost-effective solutions to climate change, then a top priority will be ecological restoration to harvest and store carbon naturally, and Judith Schwartz's new book will provide a destination and map. --Will Raap, founder, Gardener's Supply and Intervale Center
