Earth's surface has been reshaped by five mass extinctions over the course of evolutionary history, each one followed by surviving species reorganizing themselves to fill the gaps left behind. This film lays out the current numbers against that backdrop: roughly 27,000 species vanish every year, a rate that matches or exceeds the die-offs recorded during past catastrophic extinctions. Scientists and researchers walk through the evidence for treating the present moment as a sixth such event, weighing habitat loss, hunting, and industrial expansion against the natural background rate of extinction. The film keeps returning to a single question underneath the data: how much of this is driven by human activity rather than the planet's own cycles. Without a transcript or detailed source material to draw on beyond the film's own framing, the specifics here are limited, but the core argument is clear, using the fossil record's five precedents as a yardstick for measuring what is happening to biodiversity now.
