Abstract

Identifying and quantifying planetary boundaries that must not be transgressed could help prevent human activities from causing unacceptable environmental change, argue Johan Rockström and colleagues.

Crossing certain biophysical thresholds could have disastrous consequences for humanity

Three of nine interlinked planetary boundaries have already been overstepped
