It appears that life evolved from animal forms whose soft parts were inside, covered by a hard external casing, into other forms, such as ours, in which everything hard is interiorized as bone, cartilage, skeleton, while the soft is expressed as flesh, mucous membranes and skin. Those who love to fight are unevolved leftovers from a very ancient past, from the dark time when we were armoured. The newcomers amongst us become gentle, wrinkle-bearing: we bear imprints. We are clothed in soft, warm wax, we are tarnished mirrors, a warped, scratched, blotched, diverse surface in which the universe is reflected a little.

The Five Senses : A Philosophy of Mingled Bodies

The captain who unloads waste in the high seas has never seen, or rather has never let, the countless smiles of the gods emerge; that would be too demanding, or even creative. Shitting on the world, has he ever seen its beauty before? Did he ever see his own beauty? And so, he who dirties space with billboards full of sentences and images hides the view of the surrounding landscape, kills perception, and skewers it by this theft. First the landscape then the world.

This quote from Michael Serres’ compelling book Malfeasance: Appropriation Through Pollution?, in which he compares our despoiling of landscape through physical advertising, rubbish dumps and industrial waste with the territorial marking of other animals. What began with piss and shit has evolved into numerous forms of hard and soft pollution.
