Possibly, but that won't help the flora or fauna since young, planted forests have completely different ecosystems than the rainforests we're tearing down. Arguably it won't help co2 emissions much either since old forests capture enormous amounts of carbon in the ground, which planted forests don't.

Bamboo, we need to start using bamboo.

Not for wood. Forests for wood are actually larger than in the past. When forests are cleared it's for farmland, so this won't make any difference.

Plantation timber is a pretty eco-friendly material, and can be cheaper than wild timber (especially if you are in a jurisdiction that has carbon accounting).
