I have a split reaction to the rapid spread of Zika virus.
On the one hand, it’s terrifying, especially for the young and fertile. (I don’t have grown children hoping to reproduce, but I do have many nieces and nephews in that demographic.) Our natural self-interest as living organisms and members of a beleaguered species makes it imperative that we understand and control this threat: through immunization, genetic mosquito control, whatever it takes.
On the other hand, through a cold eye, such outbreaks, as well as the cancer plague that now afflicts about one in three Americans during their lifetimes, look like Earth’s immune system trying to control the cancer that is us — sometimes with whatever blunt instrument comes to hand, sometimes with an uncanny laser-guided focus: Zika targets the brain, which is, after all, the source of the trouble. It also appears to be transmitted by sex, the other source of the trouble (being, as it is, what makes more of us).
This leaves me, as a childless human who’s had my three score and ten — so anything more is gravy — feeling that if one of those natural killers came for me, I could have no hard feelings. Why me? Why not? From the host organism’s point of view, I’m one more cancer cell, or locust, or virus. Nature doesn’t care whether you hold environmentally correct views (which would make a difference only if they actually became widespread enough to re-subordinate our collective behavior to the health of the whole and rein in the metastatic human impact). It doesn’t discriminate one human from another. To the ecosystem equivalent of a natural killer cell, it’s not who you are, it’s what you are.
I fear for the young, for whom the stakes are so much higher. Owing their existence to our explosive success as a species, they are also slated to pay its price. They place their hope and faith in the continuing acceleration of our success — specifically, in science’s ability to shield us from Earth’s immune system long enough for us to proliferate and innovate towards some kind of breakthrough. Can we ever be as smart as cancer, which does such a brilliant job of outwitting OUR immune system? Can we be even smarter — figure out how to be fruitful and multiply and still keep our host alive?
We can now say that we HAVE scratched the surface. That is something. But that’s about it.
