Does any of that prevent people from dying in weather that is too hot and humid for humans? If not, I don't see how it's relevant Like what does population growth have to do with people dying from heat? Okay so the population is growing, that didn't stop the extra deaths from happening. Why does life expectancy matter? Obviously that's going to change rapidly in these circumstances, but again, still not changing the number of deaths
