US: 335M / 5,000M ton / 15 ton

Indonesia: 275M / 650M ton / 2.3 ton

Pakistan: 240M / 225M ton / 1 ton

Nigeria: 220M / 110M ton / 0.5 ton

Brazil: 215M / 475M ton / 2.2 ton

I can go on and on about the countries that are emitting less than the US. People and animals live in areas that are liveable. So countries near the equator and fertile countries will always be more populous. So how else do you propose we compare countries? Which are themselves mostly arbitrary lines as far as the earth is concerned - so why chunk by countries? It has to be per person right?
