They are a storage of CO2. If we replaced all old trees with new ones we will gain a lot of potential for CO2 capture but at the cost of releasing massive amounts of CO2 to the atmosphere.
You are right. But I think that the point was to notice that we may have lost many good trees even if we are trying to add new ones.

The CO2 is only released if we burn them. If we use the wood for building materials or other goods with long-term storage, the carbon continues to be locked up.
