Humanity Almost Went Extinct — Here’s How We Survived

Humanity has almost gone extinct more than once — and most people have never heard the full story. This video breaks down four of the closest calls in human history: the Toba supervolcano genetic bottleneck, the Black Death, the 1918 flu pandemic, and the nuclear near-misses of the Cold War. Each of these moments could have ended the human species entirely. Instead, they reveal just how fragile our existence really is — and how close we might still be to the next one.
