Many forests and grasslands across the world have been shrinking—or even disappearing—for many years. The idea of restoring forests and grasslands is nothing new. Scientists have tested many methods of restoring grasslands with positive results. In some cases, they simply plant new grass in places where it has disappeared. Some projects have even reintroduced animals and plants. In turn, these places were converted into their previous states of flourishing life. Not only does this help plant and animal species, it can also prevent the dust storms that pose a health risk to humans.
选项
答案
多年以来,世界各地的森林和草原一直在缩小,甚至在消失。重建森林和草原已不再是什么新鲜事。科学家们测试了很多重建草原的方法,获得了积极的成效。有些情况下,他们仅仅只是在草原消失的地方重新种草。有些项目甚至还重新引进动物和植物。如此一来,这些地方就恢复了之前繁荣茂盛的状态。这样不仅仅有助于动植物种群,还能防止沙尘暴给人类带来健康危害。
