Willing is not the issue. If we wait for individuals to decide they are willing to get rid of their internal combustion engines to do so and wanted to do it ASAP to make a difference, it won't happen soon enough to make that difference.
There would have to be a massive plan to quickly replace internal combustion vehicles plus widely available small mass transit devices that work like the motorcycle tricycles in Asian countries, thousands of them cruising constantly available to be waved down by passengers, and even if they were electric motor driven, the electricity to charge their batteries must be cleanly generated. Can enough of these vehicles that run on solar panels with back up batteries for overcast day be manufactured in the estimated amount of time we have left?
Even if local credit union were to become widely available, we would need to see that the computers that run the accounts are cleanly powered and that when parts that make them work break down ready replacements are available are disposed of nonpollutingly.
Agriculture would have to change so that vegan food coukd be switched over to soon enough to continue to feed everyone who needs to eat,
At every point one looks one sees these problems crying out for workable plane and leaders with the knowledge and charisma to enthuse everybody through all the changes they will have to make.
If a revised and upgraded clean green world were built and ready for its activator switch to be turned on, I would bet that a huge majority of people would be enthusiastically willing.
