memories of Italy’s Sarno, India’s Ganga, and the Buriganga in Bangladesh, of
Brazil’s Doce and China’s Yellow River. And they harken to that ugly outflow of the
Mississippi, the pollution visible from space.

But they also portend what Brazil’s notorious Cubatao River,

might yet signal: significant ecological restoration. Somehow, on a cold
late afternoon, these thoughts serve up a fitting metaphor for yet another fundamental, if odd, biological paradox, the evolution of which occurred in water, before
transmigrating to land, good for some species, fatal to others, namely, oxygen
herself.
23.4 The Oxygen Paradox
The oxygen paradox pertains to its “conversion into oxygen radicals, and other reactive oxygen species, that cause damage to cells, organs, and organisms.”
42
A substance eukaryotes cannot live without, and, in many cases, cannot live with. Whether
liquid, gas, or solid, there are scores of explanations within the evolutionary biochemical canons for the realities of oxygen and dissolved oxygen, as well as all
those untidy reactions to O 2 which create potentially lethal “oxygen-based free radicals.” Despite the apparent fundamental dialectic, life herself, with all the seemingly
contradictory behavioral norms, provides for what we primates take to be a predictable lifespan, in an aggregate of multiples, and a confusion of senseless inflictions.
Is this merely one more example, among an infinitude, of the ecological paradox we
simply must accept? It was Galileo Galilei who said that “By denying scientific
principles, one may maintain any paradox.”
