For more than a century, we have relied on chemical cures to keep our bodies
free from disease and our farms free from bugs and weeds. We rarely consider
human and agricultural health together, but both are based on the same ecology,
and both are being threatened by organisms that have evolved to resist our
antibiotics and pesticides. Patients suffer fromC.diff, a painful, potentially
lethal gut infection associated with multiple rounds of antibiotics; orange
groves rot from insect-borne bacteria; and the blight responsible for the Irish
potato famine outmaneuvers fungicides. Chemical warfare is failing us.
Fortunately, scientists are finding new solutions that work with, rather than
against, nature.
