Title: Do you need to keep planting trees to offset CO2 or is planting once enough?
Post by: Sally Le Page on 24/06/2021 14:33:46
Granville wants to know:

"If 1-2 fully grown trees are enough to sequester one's CO2 for one year, according to calculations of biomass, why is the tree not enough for the future years? Why do you need to plant a new tree every year for life? It is not like the tree looses its ability to change CO2 as it ages."

Any ideas?

Trees do not grow indefinitely large, and most do not live for ever. And there's a  lot you can do with a healthy adult tree, like turn it in to houses and paper, so it makes economic and ecological sense to keep planting young ones and cut down the old ones.
