> The analysis found there are 1.7bn hectares of treeless land on which 1.2tn native tree saplings would naturally grow.

> Crowther’s team calculated that there are currently about 3tn trees in the world, which is about half the number that existed before

I really hope this study is solid, but how can 1.2tn re-planted trees make up for a loss of 3tn logged ones? And moreover cover the CO2 of all that burned coal and oil?

Because it's not suggesting to return to pre-human numbers, but to plant without encroaching on current agricultural and urban land.
