Lead and Mercury is simple, They are neurotoxic so we stopped putting lead in paint! Kids in the US have gone from 7.5% having concerning levels of lead in their blood in 1990's to under 1% today
AIDS has killed 35 million people world wide and only by sustained effort globally been walked back from certain death to somewhat manageable but is still a crisis in many parts of the world today.
Ebola again has only been halted from mass spread by concerted global efforts to stop it's spread during outbreaks AND we now have treatment protocols
