You could even argue that it would be a net negative because plants convert carbon from the atmosphere into their own bodies, so even when they are burned to release the majority of their hydrocarbons they still take some with them in the form of carbon soot and ash. If we could convert all of the excess CO2 in the atmosphere into carbon and oxygen that would be great (maybe a little messy but great)
