Because wood grows back much faster. Or can oil, coal, and gas form in 20 to 30 years? Wood can.
YES!
Oil and coal were once wood or creatures that formed in a few decades, just as it happens today. Therefore, in those few decades, it absorbed CO2, just as wood does today while growing.
The fact that it was then transformed over millions of years and stored for millions more does not change that. The CO2 was already absorbed before.
In the end – to put it simply – it is claimed that burning fresh wood is better in terms of CO2 emissions than burning old wood.
That is logically wrong. Both are the same. So either both are bad or both are okay. You need to be honest about that.
(I sometimes also make wood fires. But I know it is not better).
