Can humankind figure out a way to rid itself of the money system and economies that human civilisation are run on and replace it with another system if need be? Like we replaced the barter system.

It seems to me that the main reason and incentive for inaction when it comes to climate change is money.It was humankind that imagined up the value of money and attached it to objects like paper notes, coins and golden rocks. If we got rid of our self-imposed need for it to survive then perhaps we could learn to co-operate for the benifit of the whole and freely share around the resources needed to combat climate change. Then if enough resources are in a country to implement an idea to combat climate change the government wouldn’t go: “We can’t do it because we haven’t got enough money to buy the resources. Then people wouldn’t have the incentive of extra money for the moment to not take steps to avoid runaway climate change. Then fossil fuel companies would not have the incentive of more money to keep sales up. I am also worried that if we don’t learn to share then after the economy is damaged by the effects of climate change that the governments will again use the economy as an excuss to not do much.
