The main problem with trees is they’re very slow. It would take decades after we started planting billions of trees a year before they’d have grown to the extend where they’d have captured reasonable amounts of carbon.
So, yes, it’s an option. But it’s a slow option we’d need to start implementing immediately if we wanted it bear fruit.
(We produce enough CO2 that it takes 40 billion hardwood trees growing for 40 years to sequester as much CO2 as we make in a year. We’d have to plant a lot of trees, and then not touch them for years, to affect the course of things)
