Explain your ecological sustainable definition of "economical"?. For if your idea isn't ecologically sustainable, then evidently it's only "economical" (generally for those that benefit from the system) in the short term.
The One Planet Development (OPD) approach that I keep referring to https://qoto.org/@Empiricism_Reloaded/110511036586999020 is sustainable economics (there are few technicalities with OPD. However, economic #degrowth solves many of the environmental issues that are being caused by overconsumption of resources and pollution).
Economics isn't some dark art, it's simply trading resources. In fact, you could even have an economy that didn't use money (just saying). The OPD approach can use standard currency plus OPD land owners may share \ trade resources with their neighbors.
You asked earlier what I mean by neoliberalism. As mentioned on the wiki page, one ideology of neo-liberalism is a growth of a global economy (more resources and more pollution. No wonder greenhouse gases aren't reducing)
