The most massive tsunami perfect storm is bearing down upon us.这场最强大的、完美海啸风暴正在击垮我们。This perfect storm is mounting a grim reality, increasingly grim reality,这场完美风暴（指独立发生时没有危险性，但同时发生时会带来灾难性后果的事件组合）正在加剧一个严峻的现实，日趋严峻的现实，and we are facing that reality with the full belief that we can solve our problems wi

So let&#39s do that. So on this bit of grassland, we&#39ll do it, but just in the foreground.那就做吧。我们将在这块小草地上实验这种方式。这只是一开始的样子。We&#39ll impact it very heavily with cattle to mimic nature, and we&#39ve done so, and look at that.我们将会在上面用大量的家畜来模拟大自然的行为，现在来看下模拟之后草地的样子。All of that grass is now covering the

This picture is a typical seasonal grassland.这张图是典型的季节性草原。It has just come through four months of rain, and it&#39s now going into eight months of dry season.刚刚经历了4个月的雨季，将要进入8个月的旱季。And watch the change as it goes into this long dry season.注意看草原进入漫长的旱季后的变化。Now, all of that grass you see aboveground h

I began helping a family in the Karoo Desert in the 1970s turn the desert that you see on the right there back to grassland,20世纪70年代我开始帮助一个在卡鲁沙漠的家庭，你们看到在右边沙漠变回了草地，and thankfully, now their grandchildren are on the land with hope for the future.值得庆幸的是，现在他们的子孙在这片土地上，对未来充满希望。And look at the amazing cha

When I was a young man, a young biologist in Africa, I was involved in setting aside marvelous areas as future national parks.我年轻的时候，是非洲的一个年轻生物学家，我参与了一个项目，为国家公园规划未来的野生区域。Now no sooner — this was in the 1950s — and no sooner did we remove the hunting,不久后——这是1950年——我们刚取消打猎，drum-beating people to prote

I took this picture in the Tihamah Desert while 25 millimeters -- that&#39s an inch of rain -- was falling.这张照片是我在提哈迈沙漠拍的——下着25毫米（一英寸）的雨。Think of it in terms of drums of water, each containing 200 liters.把它想成是装在桶里，每桶装200升。Over 1,000 drums of water fell on every hectare of that land that day.那天每公顷的土地

Clearly, we have never understood what is causing desertification, which has destroyed many civilizations and now threatens us globally.显然，我们从未明白什么导致了荒漠化，这种荒漠化已经毁掉了很多的文明社会，而现在对我们的威胁是全球性的。We have never understood it. Take one square meter of soil and make it bare like this is down here,我们从来都没有搞清楚过。像这

Today, we have young women like this one teaching villages in Africa how to put their animals together into larger herds, plan their grazing to mimic nature,今天，我们有像这样的年轻女性在非洲的村庄里传授技术，如何把他们的动物集合成一大群，如何安排计划达到模拟大自然的效果，and where we have them hold their animals overnight -- we run them in a predator-frie

I believe I&#39ve shown you how we can work with nature at very low cost to reverse all this.我相信我已经向你们展示了我们如何与大自然共处，用很低的成本来扭转这一切。We are already doing so on about 15 million hectares on five continents,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，and people who understand far more about carbon than I do calculate t
