A revelatory journey of discovery into the intricate, beautiful, and often surprising processes that convert energy from the sun into life, and how all-important these are to our survival—and our planet's future

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!

      “Photosynthesis is the original, largest, and most powerful ‘Net Negative’ technology ever,” writes biophysicist Jovine in his accessible debut, a survey of all things photosynthetic. Setting out to “communicate at least some of that tingle of glee and wonderment scientists feel when get the chance to reveal a tiny facet of the magic of nature,” he begins with an introduction to photosynthesis, laying out what it is and its discovery, which involved an 18th-century clergyman conjecturing that light might be an energy source for plants. That photosynthesis can create “forests, food, and wealth from nothing but air, sun, water, and the Earth,” Jovine asserts, remains a marvel. The author bemoans the destruction of forests, coral reefs, and savannas to make way for “shipping lanes, fields, and roads,” and outlines ways that photosynthesis can play a role in mitigating environmental damage. Revamping farming and livestock grazing practices can improve soil health, for instance, and something as straightforward as planting more trees really does make a difference. Jovine keeps a casual tone, and his enthusiasm makes him a great guide. Readers will be left convinced that “help our amazing photosynthetic friends” is a worthy endeavor.
