Mark K — The best example of greens growing weary of democracy I know of is the book The Climate Change Challenge and the Failure of Democracy.

From the publisher’s book page:

Having argued that democracy has failed humanity, the authors go even further and demonstrate that this failure can easily lead to authoritarianism without our even noticing. Even more provocatively, they assert that there is merit in preparing for this eventuality if we want to survive climate change. They are not suggesting that existing authoritarian regimes are more successful in mitigating greenhouse emissions, for to be successful economically they have adopted the market system with alacrity. Nevertheless, the authors conclude that an authoritarian form of government is necessary, but this will be governance by experts and not by those who seek power. There are in existence highly successful authoritarian structures—for example, in medicine and in corporate empires—that are capable of implementing urgent decisions impossible under liberal democracy. Society is verging on a philosophical choice between liberty or life. But there is a third way between democracy and authoritarianism that the authors leave for the final chapter. Having brought the reader to the realization that in order to halt or even slow the disastrous process of climate change we must choose between liberal democracy and a form of authoritarian government by experts, the authors offer up a radical reform of democracy that would entail the painful choice of curtailing our worldwide reliance on growth economies, along with various legal and fiscal reforms. Unpalatable as this choice may be, they argue for the adoption of this fundamental reform of democracy over the journey to authoritarianism.

And here’s one of the co-authors:

Perhaps the most significant news last week on the climate change front was the announcement that plastic shopping bags will be banned in China in six months’ time. Let me analyse why this is so significant….
Let us return to the plastic bags. The ban in China will save importation and use of five million tons of oil used in plastic bag manufacture, only a drop in the ocean of the world oil well. But the importance in the decision lies in the fact that China can do it by edict and close the factories. They don’t have to worry about loss of political donations or temporarily unemployed workers. They have made a judgment that their action favours the needs of Chinese society as a whole.
China has become, or is just about to become, the world’s greatest emitter of greenhouse emissions. Its economic growth suggests that it may soon emit as much as the rest of the world put together. Its environment is in a deplorable state, with heavily polluted rivers and drinking water, serious air pollution, both of which have a heavy burden of illness. Pollution and climate change are reducing productive land in the face of an increasing population which is compelled to import some of its foodstuffs. Its population centres will be candidates for early inundation by sea level rise and the melting of Himalayan glaciers will reduce its water supply.
All this suggests that the savvy Chinese rulers may be first out of the blocks to assuage greenhouse emissions and they will succeed by delivering orders. They will recognise that the alternative is famine and social disorder
Let us contrast this with the indecisiveness of the democracies which together produce approximately the other half of the world’s greenhouse emissions. It is perhaps reasonable to ask the reader a question. Taking into account the performance of the democracies in the reduction of emissions over the past decade, do you feel that the democracies are able and willing to reduce their emissions by 60-80 per cent this century or perhaps more importantly by approximately 10 per cent each decade?
If you say “yes” then you fly in the face of a track record of persistent failure in a wide range of environmental management leading to depletion of natural resources and fresh water, biodiversity and ecological service loss, loss of productive land and depletion of essential food sources such as ocean fish….
Liberal democracy is sweet and addictive and indeed in the most extreme case, the USA, unbridled individual liberty overwhelms many of the collective needs of the citizens. The subject is almost sacrosanct and those who indulge in criticism are labeled as Marxists, socialists, fundamentalists and worse. These labels are used because alternatives to democracy cannot be perceived! Support for Western democracy is messianic as proselytised by a President leading a flawed democracy
There must be open minds to look critically at liberal democracy. Reform must involve the adoption of structures to act quickly regardless of some perceived liberties.
