面对这些画面我有话说。如果把地球上所有的沙漠都种上树，那么大空中的二氧化碳含量将会大量下降，全球气候变暖的问题就可以得到缓解了。所以我建议大家看见有捐钱种树的项目都参与一下。阿里、微信公益里都这种项目。Facing these images, I have some meaning to express. If all the deserts of the earth can be covered with tree. The amount of CO2 the air can be largely declined. And the global warming problem can be eased. I hope we can join in the tree planting commonweal! We can see these kinds of commonweal both in ali and weixin.
我相信沙特阿联酋这些国家肯定尝试过绿化。
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。。。
