The greatest problem in conservation and pollution control is that as soon as someone introduces a new measure, however reasonable, someone else pushes back. Try to control traffic pollution(demonstrably toxic) and all the van drivers get up in arms. Try to restrict smoking, and there’s a huge uproar crying freedom, autonomy and the right to die in peace. Yes, progressive ideas may be rational and based on scientific evidence and of long term benefit. But all too often, they can give people something to lose here, now, in the short term. Everyone really, truly need conservation and pollution projects to succeed quickly, here, now as well. The answer suggests Jonathan Watts of the Guardian, is lying on the banks of the Yangtse river in China and its called Evolutionary Game Theory [1]
The Yangtse had got into a pretty sorry state over the 70 or so years up to 2020. Too much fishing, too many dams. too much pollution. An iconic species called the Baiji dolphin (Lipotes vexillifer) was even driven to extinction, a heart-breaking tragedy if ever there was one. Something had to be done. And instead of just imposing bans and top down heavy handedness, the authorities boxed clever Check this out form Jonathan:
[the policy}t was designed according to the principles of evolutionary game theory, to assess how the three main bodies affected – communities, local governments and central government – would behave depending on different applications of punishments and rewards……The government spent about $3bn on compensating and finding alternative employment for about 200,000 fishers, scrapping many of the 100,000 boats involved.
In other words ordinary people were not treated as reckless ignoramuses, but just strugglers like the rest of. They were both brought in and bought in. a lesson many governments and well meaning reformers could do well to learn from. Now the great river, one of the undoubted wonders of the world, is starting to recover. Albeit a little groggily in places. Combine that with China’s CO2 emissions starting to flatten out, and their huge lurch towards renewable power, and you may get a glimmer of hope indeed.
