What Would the Earth Be Like Without Photosynthesis?

This film imagines what Earth would be like without photosynthesis, the process that underpins nearly all life on the planet. It explores how plants, oxygen, and food chains depend on this quiet chemical engine and what would collapse without it. The thought experiment makes a familiar process feel newly astonishing. It is a fascinating watch for anyone curious about biology, ecology, and the invisible processes that keep the living world running. Free to watch in HD on Dr Documentary.
