Wikipedia (https://en.wikipedia.org/wiki/Tragedy_of_the_commons#Example...) does have global examples where tragedy of the commons has applied, like mass extinctions and climate change. These are ongoing but have already caused permanent damage.

Although, there are other large-scale examples where tragedy of the commons has been (practically) avoided: ozone depletion and Polio eradication. Wikipedia (https://en.wikipedia.org/wiki/Tragedy_of_the_commons#Non-gov...) also mentions Elinor Ostrom, but her examples involve "smaller numbers".
