为了纪念地球周,目前正在推广两种引人深思的方式来观察地球的长期变化。美国宇航局的网站和哈珀·柯林斯出版社的应用程序都展示了令人瞩目的并排卫星图像,这些图像显示了在长达 30 年或更长时间跨度内发生巨大变化的位置。 主要目的是展示我们人类是如何改变地球表面的。

美国宇航局在一个名为State of Flux的网站上发布了 160 多个对比视图。 这些清晰的图像被分为几类,例如“人类影响”(见下文)。

其他类别包括城市、极端事件(如火灾、洪水和海啸)以及土地覆盖(见下文)。 这些图像可以免费下载和使用。

从上方观看地球的第二个选择是一个名为Fragile Earth的优秀应用程序。 它更侧重于气候变化、自然灾害和人类活动如何改变环境。 该应用程序还分为几个类别,包括人类的影响、变暖的世界以及沙漠和干旱(左下方)。

Fragile Earth 的目标是向人们展示我们能够多么剧烈地改变周围环境。 该应用程序适用于 iPad 和 iPhone,它之所以引人注目,是因为用户可以通过在显示屏上前后滑动手指来查看对比图像。 当被调用时,解释图像的文本、拍摄日期以及描绘的变化原因会从屏幕底部向上滚动。 哈珀·柯林斯已将常规价格 2.99 美元降至 0.99 美元,有效期至 4 月 29 日星期日,即地球周的最后一天。
