More scientists say Earth is on the verge of collapse

Human-generated pressures, at their current pace, will likely drive our planet’s ecosystems to an irreversible collapse in the coming decades, according to a new paper in the journal Nature.

The paper, titled “Approaching a state-shift in Earth’s biosphere,” is the work of 18 scientists from Chile, Canada, Finland, the U.K., Spain and the United States.
