This depends if we've already overshot maximum sustainable population. You can run many different machines at over 100% capacity. The issue is they break down much more quickly. Water would be a good example of a resource that has stores we can use at a speed much faster than 100% of replacement rate.
(It's just a shame that renewables and other tech (plus the required behaviour changes) are coming in to maturity a couple of decades too late. Surely we just need to bridge the gap between demographic changes and adoption of cleaner tech. I might be overly optimistic on this front)
