Money,societal status, denial, just don’t give a shit are all reasons why nothing gets done. Pretty sad. It will only change when something like India or some other hot country has a wet bulb massive human and animal die off.
Westerners will say they care about these things but I don't think a million people dying in a heatwave in Bangladesh or India will do anything to curb their behavior or drive them to action.
Yup, another thing these first world countries don't seem to get: they have dropping birthrates, while other places with lower standards of living don't seem to be slowing down. When these regions get too hot or unpredictable to live, where would the refugees want to go?
