The 6th mass extinction hasn’t begun yet, study claims, but Earth is barreling toward it

In the past 5 mass extinctions, a common event is that the top predators went extinct. H. Sapiens may actually be on a trajectory towards self-extinction, i.e.: a local extinction via fossil fuel use, global trade and food production for an increasing human population and/or demand for resource use.
