Forests do a lot more than hold carbon. And many of these other uses require more than young, fast growing monocultures. Quite a lot of rainfall over land originates as transpiration from forests, for example; they're a key part of the water cycle, holding and releasing water which would otherwise just run into the sea. Likewise, a lot of species depend on healthy first habitat. Clear cut all the trees, and you lose all the species that depends on them. And all the species in adjacent ecosystems which rely on the forests. This isn't to say that tree planting and harvesting can't be a part of carbon management strategies, but that it must be done judiciously. Clear cutting everything and burying it all is as short-sighted as, say, spending a century dumping leaded CO2 fumes into the atmosphere.
