NOTHING About the Devonian Extinction Makes Sense

Trees didn’t just save life on Earth. Once upon a time, they nearly wiped it out. Around 375 million years ago, forests spread across the planet for the first time. They evolved wood, grew massive root systems, reshaped rivers, and changed Earth’s atmosphere forever. And in the process, they triggered one of the largest mass extinctions in history. This video breaks down the Late Devonian Extinction, a 20-million-year-long catastrophe that wiped out roughly 75% of all species on Earth. Giant sea scorpions vanished. Armored fish with jaws went extinct. Coral reefs that had existed for hundreds of millions of years collapsed. Trilobites, survivors of every previous disaster, were nearly erased. And the cause wasn’t asteroids or volcanoes. It was trees. Early swamp forests acted like methane chimneys, venting massive amounts of greenhouse gas into the atmosphere while simultaneously stripping carbon dioxide from the air. The result was climate chaos. Ice ages. Heat spikes. Oxygen-starved oceans. Toxic dead zones filled with hydrogen sulfide. This video explains how forests reshaped Earth’s chemistry, why the oceans suffocated, how repeated extinction pulses dragged on for millions of years, and why sharks and modern fish survived while dominant species didn’t. It’s the story of how life accidentally caused its own near-annihilation. And why, somehow, we should probably be grateful it happened.
