如果所有人類都突然消失了，會變成什麼樣子？

人類無所不在。在每塊大陸上都有人定居，人類的蹤跡甚至遍及地球上最與世隔絕的角落，包括叢林、海洋，和凍原。我們的影響非常深刻，大部分科學家相信人類在地球的地理紀錄上留下了永久性的痕跡。所以，如果地球上的每個人都突然消失了，會如何？丹克瓦特勒帶大家來探究這個主題。

If humanity suddenly vanished, our cities would quickly unravel as fires erupt, tunnels flood, and darkness falls across the globe. Within decades, plants and animals would reclaim the built environment, with skyscrapers collapsing and invasive species taking root. In the long run, biodiversity would flourish, pollution would fade, and even after millions of years, traces like Mt. Rushmore and buried technofossils would endure before nature erases them. Exploring this scenario reveals just how deeply human presence shapes—and scars—the planet.
