This sounds more like fantasy revisionist science we’ve been getting for decades. Trees job is to convert carbon dioxide with their leaves and turn it into oxygen. Why should they instead hoard poisonous carbon dioxide?? Don’t forget the part trees are being prevented from converting carbon dioxide into oxygen because 90% or rain forests have been chopped down. So the remaining 10% will be hoarding carbon dioxide instead of turning it into oxygen. Um ok yeah makes a lot of sense.
