Actually the average lifespan in the USA is decreasing.
True. I recall reading this was largely due to increasing opioid deaths. These comprised 2.3% of all deaths last year. While less than the 5% of US deaths that are due to air pollution it overtook the 1.5% due to guns (in 87's world, such things wouldn't be a concern even if they were going up by 30% a year).
Solar remains at 1%.
No, you have it wrong again. The growth rate is definitely nearer 30% at present. I shouldn't have to tell you this more than once: it's not as if you have Alzheimer's or an IQ of 70.
