Unscramble the Blue Letters

Now, sand dunes cover only about one fifth of our dtreses. And still, those extmere environments are very good pleacs if we want to stop the shifting sands. Four years ago, 23 African countries came together to create the Great Green Wall Sahara. A fantastic project, the initial plan called for a shelter belt of trees to be paletnd right across the acfarin continent, from Mauritania in the west, all the way to Djibouti in the east. If you want to stop a sand dune from moving, what you need to make sure to do is to stop the gianrs from avalanching over its crest. And a good way of doing that, the most efficient way, is to use some kind of sand chtacer. Trees or cacti are good for this. But, one of the problems with planting trees is that the pepole in these regions are so poor that they chop them down for frwieood.

Original Text

Now, sand dunes cover only about one fifth of our deserts. And still, those extreme environments are very good places if we want to stop the shifting sands. Four years ago, 23 African countries came together to create the Great Green Wall Sahara. A fantastic project, the initial plan called for a shelter belt of trees to be planted right across the African continent, from Mauritania in the west, all the way to Djibouti in the east. If you want to stop a sand dune from moving, what you need to make sure to do is to stop the grains from avalanching over its crest. And a good way of doing that, the most efficient way, is to use some kind of sand catcher. Trees or cacti are good for this. But, one of the problems with planting trees is that the people in these regions are so poor that they chop them down for firewood.
