This is exactly the problem. Above assumptions about democracy simply are not true at world level. I would imagine that if every person in the world would be able to vote equally on these topics - and everyone would have the same impact, things would look different. The rich countries are a minority population wise (or better: the people benefitting from non-ecological behavior are a minority). But when climate based refugees come, people might change their mind - or when we see in the news people dying in those affected regions… (oh wait - we already don’t care about seeing people starving… :( )
