At least five times, a biological catastrophe has engulfed Earth killing off the vast majority of species. As scientists say we’re in a sixth mass extinction, what can we learn from the past?

Unlike past mass extinctions, caused by events like asteroid strikes, volcanic eruptions, and natural climate shifts, the current crisis is almost entirely caused by us — humans.
