`Well, it's worse than that, isn't it? Mark said. 'Dolphins rely on sound to see with.'Link (Thanks, Daniel!)
'All right, so it would be like a deaf man living in a discotheque.'
'All the stroboscopic lights and flares and mirrors and lasers and things. Constantly confusing information. After a day or two you'd become completely bewildered and disoriented and start to fall over the furniture.'
`Well, that's exactly what's happening, in fact. The dolphins are continually being hit by boats or mangled in their propellers or tangled in fishermen's nets. A dolphin's echolocation is usually good enough for it to find a small ring on the sea bed, so things must be pretty serious if it can't tell that it's about to be brained by a boat.
`Then, of course, there's all the sewage, the chemical and industrial waste and artificial fertiliser that's being washed into the Yangtze, poisoning the water and poisoning the fish.'
`So,' I said, 'what do you do if you are either half-blind, or half-deaf, living in a discotheque with a stroboscopic light show, where the sewers are overflowing, the ceiling and the fans keep crashing on your head and the food is bad?'
'I think I'd complain to the management.'
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
