案例简介：乔治·斯坦梅茨 (George Steinmetz) 的照片 @ geosteinmetz/您可以通过沙漠的颜色来判断沙漠的年龄，因为每种沙粒的铁矿物需要数千年的时间才能氧化成成熟的橙色。纳米布 (Namib) 的沙丘是地球上最古老的沙丘之一，并由沿海雾及其露水培育的草丛稳定下来。这些是脆弱的生态系统，有活生生的隐生土壤。他们可能会因粗心的汽车痕迹而伤痕累累，但现在受到严格的法律制度的保护，该制度可以永久保存它们。要从上面探索更多我们的世界，请关注 @ geosteinmetz。

案例简介：Photo by George Steinmetz @geosteinmetz / Youcan judge the age of a desert by its color, as it takes thousands of years for the iron minerals of each sand grain to oxidize into a ripe orange. The dunes of the Namib are among the oldest on Earth and stabilized by colonies of grass that are nurtured by the coastal fog and its dew. These are fragile ecosystems, with living cryptobiotic soils. They can be scarred by careless car tracks, but are now protected by a strict legal system that preserves them in perpetuity.
