It is a massive win-win for rich countries to develop technologies to prevent pollution and transfer it to poorer countries at low or no cost. It's like cleaning your own house & then ensuring the neighbors don't dump trash in through the windows. Self-interest alone dictates this! And self-interest also says we should make sure the poor in highly-populated countries get the nutrition they need to live decent lives, rather than having so little to lose that they start wars!
