ok, seems like we are looking at this from different perspectives. You look at it from fairness to people and I look at it from fairness to earth. I argue that because pollution is so concentrated within the area, it destroys that part of earth more, this does not include anything to do with fairness towards people. But you are absolutely right if you look at it from perspective of being fair towards people. I am not at all against helping people though, I totally support destroying parts of the environment if it reduces overall suffering and progresses wellbeing of individuals in need. But my initial argument was that, social issues aside, looking specifically from environmental impact, per capita is not a good way to judge impact of the country.
I agree per capita/ per country is not the best way. Ultimately it comes to each individual don't you think ? . What does each every one of us directly or indirectly contribute . Any other grouping like country is always going to be arbitrary.. we need to each individually, in local, regional, national government, vote for the people who care and do the best we can irrespective what any one is doing or not. We need make them reduce too yes, but getting our shit together should be the priority
You are correct environment is not reason we should be worried . it is about the people, not the planet. 99% of the all species are already extinct one more large scale extinction event while terrible is not the end of life on this planet and the planet has seen far worse, life will survive long after we are gone. Sea level raise will adversely 60 % of the human population who live in the coast many of whom are poor. Changing weather patterns and climate change will affect the developing countries far more than first world countries who will have the resources to manage the effects . There are whole island countries that will disappear within the turn of the century. This is why developing countries are in very touch spot, they will need to balance both development of basic services and also find a meaningful solution to the problem.
