Historia de las extinciones masivas

The video discusses five historical mass extinctions: Ordovician-Silurian, Late Devonian, Permotriassic, Triassic, and Tertiary Cretaceous, highlighting causes like sea level changes, volcanic eruptions, and meteor impacts. It also addresses the potential sixth extinction driven by human activities such as pollution and overpopulation, emphasizing the need for awareness and action to prevent further biodiversity loss.
