看看通常的世界平面地图,你会发现格陵兰岛几乎和非洲一样大。但事实远非如此。非洲是格陵兰岛的14倍大。平面地图严重扭曲了国家和大陆的面积,这是将球面表面转换为方便的矩形的结果。陆地面积向两极方向变得越来越夸大。

因此,我们往往低估了靠近赤道的国家的面积,而大大高估了靠近两极的国家的面积。在我们的实际星球上,非洲比中国、印度、美国本土和大部分欧洲加起来还要大!《大众科学》刚刚发布了一张比例正确的图像,展示了非洲是如何吞并这些国家(包括日本)的。事实证明,沙特阿拉伯的面积比法国、西班牙、德国、波兰和意大利的总和还要大。

为了记录,以下是地理面积列表。的确,非洲是一个大陆,而不是一个国家,但我认为你会被它比你可能想象的要大得多而感到惊讶。认识到非洲的真实大小也有助于我们理解解决非洲的贫困和粮食挑战可能有多么艰巨。
