This is what complicates the whole issue of “socialized medicine”.
A large number of diseases and deaths are caused by collective problems. Why should the individual have to pay the externalized costs of others? This is particularly problematic as the poor live in the most polluted areas while it is the rich living in the least polluted areas who benefit most from the externalization of costs.
I’ve never come across a conservative or libertarian who can offer a useful response to this kind of data:
“About 40 percent of deaths worldwide are caused by water, air and soil pollution, concludes a Cornell researcher. Such environmental degradation, coupled with the growth in world population, are major causes behind the rapid increase in human diseases, which the World Health Organization has recently reported. Both factors contribute to the malnourishment and disease susceptibility of 3.7 billion people, he says.”
