為了紀念地球周,目前正在推廣兩種引人深思的方式來觀察地球的長期變化。美國宇航局的網站和哈珀·柯林斯出版社的應用程式都展示了令人矚目的並排衛星影像,這些影像顯示了在長達 30 年或更長時間跨度內發生巨大變化的位置。 主要目的是展示我們人類是如何改變地球表面的。

美國宇航局在一個名為State of Flux的網站上釋出了 160 多個對比檢視。 這些清晰的影像被分為幾類,例如“人類影響”(見下文)。

其他類別包括城市、極端事件(如火災、洪水和海嘯)以及土地覆蓋(見下文)。 這些影像可以免費下載和使用。

從上方觀看地球的第二個選擇是一個名為Fragile Earth的優秀應用程式。 它更側重於氣候變化、自然災害和人類活動如何改變環境。 該應用程式還分為幾個類別,包括人類的影響、變暖的世界以及沙漠和乾旱(左下方)。

Fragile Earth 的目標是向人們展示我們能夠多麼劇烈地改變周圍環境。 該應用程式適用於 iPad 和 iPhone,它之所以引人注目,是因為使用者可以透過在顯示屏上前後滑動手指來檢視對比影像。 當被呼叫時,解釋影像的文字、拍攝日期以及描繪的變化原因會從螢幕底部向上滾動。 哈珀·柯林斯已將常規價格 2.99 美元降至 0.99 美元,有效期至 4 月 29 日星期日,即地球周的最後一天。
