A Dying Forest Rainforests provide much of the world's oxygen supply. But the forests' exotic trees and animals are being destroyed to make room for farms and roads. People have been trying to conserve rainforests for years. But another type of forest—the cloud forest is just as important and beneficial to humans. Cloud forests are also in danger of disappearing, but little is being done to save them. These forests are located at the tops of mountains, generally near the equator. These humid, wooded mountaintops are mainly in African and Central and South American countries. They are called "cloud forests" because their height allows for the formation of clouds among the trees. Rainforests produce large amounts of oxygen. Cloud forests produce comparative amounts of water. The trees in these forests pull water out of the clouds. The moisture gathers on the leaves. When it drips, it is deposited into streams. The streams flow into towns at the bottom of the mountain. Then, the water is distributed to people. The yearly cumulative rainfall in these areas is 173 to 198 centimeters. Cloud forests can pull in up to 60 percent of that. This water is crucial to the plants and the people in the area. It helps them survive. Cloud forests are also the birthplace of countless species of plants that can't be found anywhere else. One small cloud forest has the capacity for as many types of plants as there are in all of Europe. There are so many, in fact, that scientists haven't made a comprehensive list of them yet. These forests are being destroyed with increasing frequency. Trees are being cut down, and roads are being built in their place. Some people have an objective to get federal money to protect the forests. But they have had little success. Another strategy is to replace the destroyed plants. That, too, has been difficult because the plants are so unique. There's plenty of work to be done, but saving the cloud forests is still a possibility.

热带雨林为世界提供了大量的氧气。 但是森林里的外来树木和动物正在被摧毁，以便为农场和道路腾出空间。 多年来，人们一直在努力保护雨林。 但是另一种森林——云雾森林对人类同样重要和有益。 云雾林也有消失的危险，但人们几乎没有采取任何措施来拯救它们。 这些森林位于山顶，通常靠近赤道。 这些潮湿、树木繁茂的山顶主要分布在非洲和中南美洲国家。 它们被称为“云雾森林”，因为它们的高度允许在树木之间形成云。 热带雨林产生大量的氧气。 云雾林能产生相当数量的水。 这些森林里的树木从云层中吸收水分。 水分聚集在树叶上。 当它滴落下来，就会汇入溪流。 这些小溪流入山脚下的城镇。 然后，水被分配给人们。 这些地区的年累积降雨量为173至198厘米。 云雾森林可以吸收其中的60%。 这些水对该地区的植物和人们至关重要。 这有助于他们生存。云雾林也是无数其他地方找不到的植物的发源地。 一个小小的云雾森林所能生长的植物种类就相当于整个欧洲的植物种类。 事实上，它们太多了，科学家们还没有列出一个全面的清单。 这些森林正日益频繁地被破坏。 树木被砍伐，取而代之的是修路。 有些人的目标是获得联邦资金来保护森林。 但他们收效甚微。 另一个策略是替换被破坏的植物。 这也很困难，因为这些植物是如此独特。 还有很多工作要做，但拯救云雾森林仍然是一种可能。
