Biomass clarity
The term "biomass" includes fossil fuels and includes any organic matter produced as a result of photosynthesis since prehistoric times.
The current environmental crisis and the resultant economic crisis are consequences of the political notion that human progress involves never-ending population explosion and economic growth. Since economic growth is the cause of the problem, it cannot be the soloution.

This is only one aspect of the overall global problem of population explosion predicted by Malthis at the beginning of the industrial revolution.
A range of environmental pollution problems, involving irreversible dispersal of the limited reserves of metals on which we depend, is also involved.
