> The problem comes in when the replanting of those trees does not happen or they are not cared for well enough for them to survive.

When we're talking about old growth forests, there is no "replanting them" in any meaningful way. They grew in conditions that may no longer exist, and would take multiple human lifetimes to regenerate even if they were replicated. You may as well be suggesting that the fossil fuel problem be solved by hatching more dinosaurs.

Replanting and regrowing is valid for areas that have already been logged, and there is certainly an argument for responsible forestry with areas designated for repeat harvest, the same as any other crop.

Unlogged/old growth areas, however, should be considered inviolate at this point.
