It's a clunky word for a miracle: Photosynthesis. But there's no life on Earth without it. For biologist Raffael Jovine, it's a consuming passion, a great unsung force of nature. He makes his case in How Light Makes Life, a catalog of living wonders--and a blueprint for a better planet. Imagine harvesting pure sunlight to use as fuel, while turning carbon dioxide into breathable oxygen. This is what a leaf does every day. And photosynthesis isn't just for plants: Corals partner with photosynthetic organisms to create the most productive habitat on Earth. Slugs eat chloroplasts as natural green camouflage. Hornets use photosynthesis as an innovative means of air-conditioning--and much more! The revelatory vision of How Light Makes Life is how we ourselves might harness the power of photosynthesis: to repair ecosystems, stabilize the climate, and grow more food sustainably. On this vivid journey, you'll see how every seed contains the key to our future--through the photosynthetic pigments in your own eyes!
