This came as a pleasant surprise!
The world is literally a greener place than it was 20 years ago, and
data from NASA satellites has revealed a counterintuitive source for
much of this new foliage: China and India. A new study shows that the
two emerging countries with the world’s biggest populations are leading
the increase in greening on land. The effect stems mainly from ambitious
tree planting programs in China and intensive agriculture in both
countries.
