Is COVID A First World Problem? We Are Killing Ourselves With Chemicals

COVID has overwhelmingly affected the first world worst, developing nations least, by almost every metric. Total cases, cases per capita and deaths per capita, why? Why is the same true for food allergies, sperm counts and obesity? I have my theory - we are killing ourselves with chemicals.

 

*I meant to make a distinction with South-East Asian countries that are still first world but fit the same paradigm of the developing nations.
