We know that during the usage of commodity currencies, the scarcity of metals like gold and silver narrowed the money supply and did not allow economies to grow out of a specific natural capacity by forcing depressions that happened due to the lack of a medium of exchange and in turn, the economic incentives for production.
Fiat standard, however, allows the central banks to affect the GDP as they see fit; they might choose monetary policies that cause the enlargement of the economy, oblivious to the environmental capacity of their countries; this has, of course, resulted in a population boom during the past century but also caused problems within the environment.
Technology has increased our productivity and helped us dodge the Malthusian trap, but even if we look at Technology as a scarce accumulative resource that also takes time and energy to be amassed (unlike Fiat money), is it possible to blame Fiat Standard as a contributor to Humanity's environmental predicaments?
