Genetic engineering could unleash a deadly pandemic or lead to a “new eugenics” with very sharp teeth.
If nature has rights, that means everything does, which devalues “rights” just as a wild inflation deflates the worth of currency.
Having ourselves turned into dirt — or worse — reflects at least an implied philosophical view that it doesn’t ultimately matter that we ever existed.
