Which resources are over consumed and by how much? The article does not say.
Sand for construction, fish, arable soil, potable water from artesian basins, rainforest lumber, other ancient forest lumber, for starters. A lot of other finite things are spoiled or being spoiled on account of them being part of the global commons which we are trashing, too. I would recommend you seek some literature on this topic, as a number of these points are well documented.
