What an ignorant comment. It just shows a failure of supposedly "superior" Western education, your citizens are deliberately kept uninformed in a desperate attempt to hold on to the power that was unfairly acquired by exploiting much of the world. Your arrogance just cannot bear equality, can you? The days of Western dominance are numbered, you cannot stop it. World power has been gradually shifting eastwards, rightfully. This is the Asian century.
Literally the only thing that matters is CO2 per capita. India's is way low. The low scientic output is a consequence of low per-capita income, it has been increasing and will keep increasing, will definitely cross Italy's (having lived in South Europe I know how the culture here is). It's only a matter of time. India's population has always been historically very high due to fertile lands. It would have been much lower, but 200 years of British colonialism deliberately kept Indians in poverty, keeping birth rates high. And suggesting population reduction - how exactly will you do that? Genocide? War? Try it and see how that goes.
You should focus on reducing your arrogance, racism, denial of facts, and over-consumption. You are not better than others. Learn some morals. The real solution to climate change is science & technology. Our current consumption level is just not inline with the current renewable tech.
You just want to forcefully keep the rest of the world poor so you can enjoy driving your SUVs and eating steaks, while somehow blaming the rest of the world based on some made-up metrics. Guess what that's not gonna happen. Try it if you can.
