But this is the problem of exponential growth - you can sustain it without even noticing the detrimental effects, until suddenly you can't. The resource usage of all the doubling time periods until the last one would have used up only 50% of the resources available(this could be millions of years, depending on the exponent), and then suddenly the last one would use up all the resources left. This is repeatedly exemplified in Professor Allen Bartlett's talk "Arithmetic, Population and Energy"(video link at specific point: https://youtu.be/sI1C9DyIi_8?t=1337 https://youtu.be/sI1C9DyIi_8?t=1337 transcript: http://www.albartlett.org/presentations/arithmetic_population_energy_transcript_english.html http://www.albartlett.org/presentations/arithmetic_populatio...)
