Denis de Rougemont, one of the early pioneers of ecology, wrote in 1977:

[I] feel it coming, a series of disasters created through our diligent yet unconscious efforts. If they’re big enough to wake up the world, but not enough to smash everything, I ‘d call them learning experiences, the only ones able to overcome our inertia.

(de Rougemont cited in Partant 1979)
