为什么森林能净化空气？
1、森林中的植物通过光合作用吸收二氧化碳，释放出氧气，从而增加空气中的氧气含量。
2、森林里的植物和微生物能够吸收并分解空气中的有害气体，如二氧化硫和氮氧化物，减少空气污染。
3、森林的树木和植被能够捕捉空气中的颗粒物，如灰尘和烟雾，通过叶片上的粘液吸附这些污染物，净化空气。
4、森林中的土壤和微生物能够分解有机废物，释放出有益的气体，如甲烷和氨气，同时减少有害气体的排放。
5、森林的茂密植被能够减少地表径流，减少水土流失，从而间接减少空气中的悬浮颗粒物。
总之，森林通过光合作用释放氧气、吸收有害气体、捕捉颗粒物、分解有机废物和减少水土流失等多种方式，有效净化空气，为人类提供健康的生存环境。
