"Once a threshold-induced planetary state shift occurs, there's no going back. So, if a system switches to a new state because you've added lots of energy, even if you take out the new energy, it won't revert back to the old system. The planet doesn't have any memory of the old state."
These projections contradict the popularly held belief that the extent to which human-induced pressures, such as climate change, are destroying our planet is still debatable, and any collapse would be both gradual and centuries away.
This study concludes we better not exceed the 50 per cent mark of wholesale transformation of Earth's surface or we won't be able to delay, never mind avert, a planetary collapse.
We've already reached the 43 per cent mark through our conversion of landscapes into agricultural and urban areas, making Earth increasingly susceptible to an environmental epidemic."
