"A continent ages quicly once we come. The natives live in harmony with it. But the foreigner destroys, cuts down the trees, drains the water, so that the water supply is altered and in a short space of time the soil, once the sod is turned under, is cropped out and, next, it starts to blow away…The earth gets tired of being exploited. A country wears out quickly unless man puts back in it all his residue and that of all his beasts…We are the intruders and after we are dead we have ruined it but it will still be there and we don’t know what the next changes are."
— Ernest Hemingway, Green Hills of Africa (in which he writes of his awful hunting exploits)
