The normally dry northern region of Argentina has a problem of biblical proportions.
Farmers there are struggling with a massive outbreak of locusts. Dark clouds of the green-brown bugs cast shadows when they fly overhead and when they land, they cover the ground.
"It is really, really, amazing when you see the locusts because you see millions of them together," said Juan Pablo Karnatz, who raises cattle in Santiago del Estero, about 600 miles northwest of Argentina's capital, Buenos Aires. "When you think they can be more millions flying around, it could be a disaster."
