re: Absolutely.
Eventually, technology caught up with the natural resilience of many resources, and it became possible to actually use it up, or deplete it to the point where it didn't become useful any more.
What you fail to say, but is relevant, is that for each of these "decision points" the people busy using the resource up didn't recognise, or refused to acknowledge, the passing of the milestone.
How is this different from reaching the ultimate capacity of the Atmosphere itself? Something has to give first, if there is exponential growth of industrial by-product. Maybe it would be the world's oceans, or the atmosphere, or the phytoplankton, or something else.
the way things are going, it seems that we're going to run out of atmosphere - or some key parts of it.
We lost Ozone a few years back. Now we're losing the CO2 balance.
Do you want to wait till we lose free oxygen?
