to make a big difference we’d need to remove north of 10 gigatons of CO2 from the atmosphere every single year. 1 Tree absorbs 1 ton of CO2 in 40 years. You need 40 trees to absorb 1 Ton a year. 40 Trees x 10 Billion = 400 Billion Trees.

眼下为420PPM
买电动车！ 骑脚踏车！ 步行！ 关爱地球！
这个过程会产生多少二氧化碳？
问题高级！
有人回答过，我沒能理解透，知识有限😰
空中捕碳最环保的方法，难道不是多种树？因为人类废气二氧化碳正是绿色植物的食物，通过光合作用吸收二氧化碳，释放其他物种需要的氧气，上亿年的完美自然循环.
但是种树就没法，炒作环保新概念，申请大量经费，和占领道德制高点了.

就知道抛出天文数字吓唬群众 真的需要每年吸收这么大量嚒？什么模型，假设和数据？之前的气候研究操纵数据误导大众也都被曝光过吧. 现有植被自身的吸收呢？二氧化碳浓度高本身也会刺激绿色植物生长和吸收从而达到平衡 这种工业吸收方法自身也是碳排放的大户吧，而且极度耗能 树木一旦种植完成，简单维护就能持续多年甚至百年

从空气中remove CO2有多少种途径？
（刚才没弄明白＂碳中和＂是什么意思，原来是一个企业的零排放）
目前还没发现可行的方案，绝大多数其实都在骗钱
