木を植えることはいいことだ。われわれは無条件にそう考えがちだ。
でも、乾燥地帯に木を植えれば、少ししかない木が吸い取られる。悪くすると地下水が枯かれ、川の流量も減る。
よく考えてみれば当たり前のことだろう。しかし、森林の役割を重視するあまり、自然の循環を忘れた「植林神話」が世界に広がっているそうだ。

Planting trees is a good thing. We tend to think so unconditionally.
But if trees are planted in an arid region, they will absorb the little water that is available. In the worst case, groundwater may dry up and river flow may also decrease.
If you think about it carefully, this is probably obvious. However, it is said that because too much emphasis is placed on the role of forests, a “tree-planting myth” that overlooks the natural cycle has spread around the world.
