Social media and phones are environmental factors. Increasing obesity is definitely a factor. Whether sperm and testosterone are decreasing is still speculative because the old data being used for comparisons is pretty poor. I think air pollution has actually gotten better since the 80s last I checked. Maybe increases in 'forever chemicals' are having some effect.
