The ocean has far more effect on co2 than trees. The lush rain forests in South America are C02 neutral, because there is so much life in the rain forest it uses up all the oxygen it produces. The idea that the rain forest are the “lungs” of the earth is just a myth, the oceans are.

Yes, but trees are good at short term carbon capture. And getting back more productive space for our ecosystems is also an important goal.

Sure, it's nothing of what we'll have to sequester, but - as I already mentioned - currently it's quite a low hanging fruit.
