The sixth extinction is the idea that humans are causing the next ‘big’ extinction since the dinosaurs, by destroying/transforming the land and air, thus causing the death (directly and indirectly) of a vast number of species.
The sixth extinction, or the Holocene extinction, refers to the period of time 10,000 years ago to the present day, or the period that humans have reigned the planet, during which many plants and animals have become extinct. The International Union for Conservation of Nature has recorded 875 extinctions since 1500 AD, though scientists estimate that at least 20,000 (or as many as 2 million) more species have become extinct in the last century alone. The Holocene extinction is referred to as the sixth because there have been five other major periods of extinction in Earth’s history.
