And wipe out an insect population - remove it from the scene.
They call it a “gene drive system.” It involves cutting DNA
And injecting a choice sequence that would propagate away
Through an entire species, and thereby provide
Complete control of its offspring, as its organ cells divide.
An example: In the lab it changed fruit-fly generations
That continued to display the thusly- introduced mutation.
So far, scientists have been reluctant to try the system in the wild,
Even though some applications might appear to be worthwhile.
We have learned that to change Nature's balance, one should proceed with healthy fear,
For unexpected consequences may quite possibly appear.
If one would wipe out generations of malaria-causing pests,
What would happen to the species that millions of the pest ingest?
Will the move affect the food chain with consequences dire?
Will the newly-found technique some calamities inspire?
So, while geneticist their “gene drive” scheme enthusiastically extol,
There appears to be a need for some societal control...
