It is the international day for biodiversity and the ants are back in their colony; the dust mites sleep still; a shoal of mackerel flashes by; lions yawn; a lone curlew prods the shoreline with its bill; cows head towards the gate; a sheep chews dry grass on a high promontary; the bats hang till dusk; antelope twitch; a crow crosses the river; a dolphin cuts the surface with its fin; a monkey cheers; a human traverses a dusty road, enters an air-conditioned building and sips a cool water. He coughs, winks, and then he orders: let the onslaught commence.
