"Mankind has probably done more damage to the Earth in the 20th century than in all of previous human history"
About this Quote
The 20th century matters here because it’s when human impact stops being local and becomes systemic. Two world wars, an economy built on oil, the Green Revolution’s chemical intensity, industrial fishing, plastics, nuclear testing, mass tourism, mass everything. Cousteau is compressing the century into a single moral metric: not progress, not prosperity, not freedom, but damage. That’s the subtextual punch - our most celebrated era of modernization doubles as a geological vandalism spree.
As an explorer, Cousteau’s authority is sensory as much as scientific. His intent isn’t to offer a data point; it’s to reframe responsibility. If a few generations can out-strip millennia of harm, then “human nature” isn’t the culprit so much as human scale: machines, markets, and the fantasy that the ocean is infinite. The quote works because it turns history into an indictment of speed. The crime isn’t that we changed the Earth; it’s how quickly we learned to do it.
