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.

While I agree that tree plantations aren't as biodiverse as natural forests, I had been lead to believe that young, fast growing trees sucked in more carbon than mature, stable forests.

Do you have any citations for why forests are better, CO2-wise? My google search results turned up a mixed bag.
