China Planted 78 Billion New Trees, and Seriously Messed Up Its Water Cycle
(www.popularmechanics.com)
Popular Mechanics is US-based, so they use short billions: 1bio = 1 000 000 000.
You are right, long billions (1bio = 1 000 000 000 000) would be a lot more. Though even that would still be possible, but then ~35% of the chinese population would have to be employed in planting trees.
