看看通常的世界平面地圖,你會發現格陵蘭島幾乎和非洲一樣大。但事實遠非如此。非洲是格陵蘭島的14倍大。平面地圖嚴重扭曲了國家和大陸的面積,這是將球面表面轉換為方便的矩形的結果。陸地面積向兩極方向變得越來越誇大。

因此,我們往往低估了靠近赤道的國家的面積,而大大高估了靠近兩極的國家的面積。在我們的實際星球上,非洲比中國、印度、美國本土和大部分歐洲加起來還要大!《大眾科學》剛剛釋出了一張比例正確的影像,展示了非洲是如何吞併這些國家(包括日本)的。事實證明,沙烏地阿拉伯的面積比法國、西班牙、德國、波蘭和義大利的總和還要大。

為了記錄,以下是地理面積列表。的確,非洲是一個大陸,而不是一個國家,但我認為你會被它比你可能想象的要大得多而感到驚訝。認識到非洲的真實大小也有助於我們理解解決非洲的貧困和糧食挑戰可能有多麼艱鉅。
