是呀，在沙漠种树，应该是需要大量人力、物力和财力，而且应该是地貌也有限制吧。但真要能全种上，真的对气候会产生很积极的影响。我现在的想法是在屋顶上做绿化，屋顶上方也是很大的城市空间还没有好好利用。All right, planting trees in the desert need much people, materials and funds. And the geomorphology has been limited. But if be planted, it will have positive effect to the earth. Recently, my idea is to plant on the roof, which is large space of cities we have not use well. 外国人看我这英文会不会疯了。。。
