Earth Day Is Wrong, It Should Be Human Day

I am afraid of cities. But you mustn't leave them. If you go too far you come up against the vegetation belt. Vegetation has crawled for miles towards cities. It is waiting. Once the city is dead, the vegetation will cover it, will climb over the stones, grip them, search them, make them burst with its long black pincers; it will blind the holes and let its green paws hang over everything.

- Jean-Paul Sartre in Nausea
