You need to actually plant and manage the forest. Letting fields go to fallow wont be enough. I’m talking about selecting tree species that grow fast and intake carbon at a higher rate then others and then cutting, processing, and replanting in a rotation pattern(so wild life and move from section to section).
Also, many people are vegans because of animal ethics or because it’s trendy, but aren’t really thinking about larger issues. Think of all the celebrities that are vegan, but fly private jets.
