These "planetary limits" correspond to thresholds that must not be exceeded in nine areas so that ecosystems can guarantee the habitability of the Earth. Six of these limits are largely exceeded and two are approaching warning thresholds.

Climate change, deforestation, loss of biodiversity, the amount of synthetic chemicals (including plastics), the lack of fresh water and the balance of the nitrogen cycle are six limits that have been largely exceeded, according to a study by a team of 29 scientists.
