That's 200 trees for every single person on the planet, each year, again and again. And they need to live long enough to become average trees, so you need to plant more than that because quite a few won't make it.

Where do you find the space for that, and the labour?!

Amount of land available for reforestation as of 2019 is enough for 1.2 trillion native saplings.

We could also set aside more land for reforestation as well.

Finding labor is easy.

This is an easy problem to solve, we just need to build up the knowledge that it is possible and then execute on it. Right now most people have never even considered things this way because they’re only exposed to doomer talk whenever climate change gets discussed. :(

Room for saplings is not the same as room for average sized trees. And it's only for a single year, we'd need to do this in perpetuity.

It would probably use land that's currently in use for agriculture, in a time when huge areas of old growth rain forest are cleared to make more space for agriculture. One country deciding to turn pasture into forest would probably cause more forest to be lost in Brazil, of a type that stores _way_ more CO2 per hectare.

I think we should start with getting better at preventing and fighting huge forest fires, and to stop considering wood pellet burning as "renewable energy".

Any further focus on planting trees only distracts from real solutions, imo.
