"tolerated" nothing like we've thrown at it in exponentially increasing form every year since 1900... and by all accounts it's not "tolerating" it very well at the moment. Fisheries? Sea water contamination? Air pollution? Groundwater contamination (fracking? agricultural runoff?) Rainforest loss (The Amazon! how many hectares lost per day? Palm oil plantations supplanting Indonesian rainforest, etc...) all on top of human caused climate change...
