I can't wait until they makes these no cost, low-maintenance, and self-replacing. Oh man, just think of how easy it would be to fix our climate issues!

Trees very quickly stop being effective though. As soon as they die, they return all that captured CO2 back into the atmosphere
You'd also joined to plant billions of trees just to keep up with current CO2 emissions, let alone all part emissions
Basically, to convert all CO2 from the atmosphere into oxygen you'll need to spend the same amount of energy as you got out of it by burning fossil fuels. With losses included, you can triple that. Add to that the energy required to gather the CO2 and the e energy required to safely store it and you can easily quadruple it
So basically take all the energy we've generated since the industrial revolution, quadruple that, and that will be the amount of energy we'll need to spend to remove the CO2 from our atmosphere. If for the next, say, 200 years we stop emitting CO2 and double our output, we spend 50% of the world's power on CO2 scrubbing, we'd end up with a clean atmosphere. That is being generous
Planting a few trees won't do anything at all
Planting entire forests the size of larger countries would do little
We opened Pandora's box and it'll cost us centuries to close it
