We are already doing so on about 15 million hectares on five continents, and people who understand far more about carbon than I do calculate that, for illustrative purposes, if we do what I am showing you here, we can take enough carbon out of the atmosphere and safely store it in the grassland soils for thousands of years, and if we just do that on about half the world's grasslands
我们正在全球五大洲 大约1500万公顷的土地上 实施这一计划， 为了说明这个计划的效果 一些远远比我更了解碳元素的人 计算得到了一些结论， 如果我们按照这样去做， 我们就能减少大气层中足够多的碳 将它们安全的储存于草地土壤中 达千年之久， 如果全球一半的草地都实施
