随着更多的水分的流失，会有更多的侵蚀，同时旱情会让啮齿类动物数量上升，这又会毁坏土壤。
As more water runs off, there is more erosion, while the drier conditions allow for a rise in the rodent population, which further decimates the soil.
他们的发现已于今日发布在《自然》杂志上，或将促成对吸附空气中水分的新材料的研发。
Their findings may lead to the development of new materials that are able to capture water from the air.
一些人已经设计了各种算法，可利用卫星针对地表温度收集数据，计算出地球吸收和蒸发水分的速率。
Some have designed algorithms that use satellite data on surface temperatures to calculate the rate at which plants are absorbing and transpiring water.
城市中因为缺少植物，地表使用了不挥发水分的材料，所以热量无法散掉，造成了城市热岛现象。
By replacing plants with impervious surfaces, cities trap heat, and create a phenomenon known as the urban heat island.
而光合作用中分解出的氧粒子，最终形成了氧气，作为“加工废料”，随着水分的蒸散通过气孔排放出去。

他说："我们认为这种趋势不会持续太长时间，因为将会出现一些限制因素，像水分的可利用性及土壤养分。"
“We don’t think this can persist for too long because other limitingfactors will come into play, like water availability and soil nutrients, ” hesaid.
但是如果空气静止不动，那么吸收了水分的空气就会停留在潮湿物体的周围，干燥的过程就会非常缓慢。
