The drastically changes you propose is deforestation. It is significantly more of a factor in high CO2 thanfossil fuel use. It also makes sense ecologically to stop the practice. The loss of plant respiration as well as the release of plant carbon into the atmosphere are significant.
Fortunately, the resource is renewable and can also be replanted at a fraction of the cost of the Paris Accord, and it wouldn’t cripple our economy or change our way of life significantly. But that is really the underlying point of the Paris Accord.
