Holding rich countries liable for greenhouse emissions

Rich countries (and rich businesses) are responsible for most of the greenhouse emissions that have destroyed nearly all of the food growing in Pakistan, as well as a large fraction of its housing. They ought to be held liable.

However, as experience with Covid-19 vaccines shows, rich businesses don't hesitate to drive people to death for their profit, and rich country governments mostly serve those rich businesses. Even when it comes to saving the lives of their own future citizens from the consequences of global heating, those governments are paralyzed.
