Trees when growing convert CO2 to O2, and when burning the wood it simply balances the equation. Meaning, no additional CO2 is generated/released. So why is this not considered Zero Emissions (aka “green”)??

Also, why are we not encouraging power plants to burn wood for use in their steam turbines generators?? Firewood even in large volumes is exceptionally cheap and very renewable… In fact, large amounts of smaller “non-ideal” trees are just left to rot in the fields many times by loggers…
As far as running out of trees… Trees are easy to grow as pulp mills will no doubt testify to. Meaning, they are just big weeds if you think about it.

Also, trees do not remove CO2 long term. Meaning, when they are burned or simply rot, they release all the CO2 they converted.
Carbon Monoxide is only produced if the wood is not completely burned. Also, “soot” as you call it is also called Potash, and is one of most sought after fertilizers.

Next, I cannot find any data on any health concerns… Burning forests have been with us since the beginning of man…
