I disagree. Of course more people will pollute more, it’s basic math so if a country with 10 millions inhabitants produces 5 times as much greenhouse gases as a country with 1 million inhabitants, the smaller country is the one which should do more. Global warming (and pollution in general) is a global issue, we can’t ask people to produce less because they happen to live in a bigger country. The fact that the EU or the US produce more than half the amount of GHG than India or China with not even half their population is insane.
I am not saying China is doing enough, simply that we can’t point our finger at them when we all pollute more.
