With the same page of the newspaper lamenting flooding in Iowa and drought in Florida, it seems that nature has turned against us in an almost biblical way. A more biblical plague than locusts would be hard to conceive, however, so when my wife pointed me to a current video of a locust invasion in Russia, I took notice. In the United States we seldom consider locusts since they have largely ceased to be a problem with the extinction of the Rocky Mountain locust for unknown reasons, last century. One of the more interesting books I’ve read over the last few years was Jeffrey Alan Lockwood’s Locust: The Devastating Rise and Mysterious Disappearance of the Insect that Shaped the American Frontier. Because the locust is not an American problem, biblical literalists like to transform biblical locusts into something else. The transformation is not necessary. We’ve eliminated the large predators from our planet, and the small ones often go unnoticed.

Each year as I lecture on the book of Joel, I spend a little time with locusts. The Asian varieties of locusts tend to reproduce rapidly and prolifically in the desert. Quickly exhausting the sparse food supply, they take to the air and fly for, literally, greener pastures. They can fly for three days without stopping which means they are suddenly there and eating everything. They look like divine judgment. Each locust eats its own body weight in green matter daily, and when a swarm can contain over 100 billion locusts, that can add up to 50,000 tons of food a day. Like poorly mannered house guests, locusts stay until all the food is gone, then leave. They are fully capable of devastating entire nations.

Hal Lindsey famously converted Joel’s locusts into military helicopters, claiming that they presaged the end times. Decades later we are still here and so are, apparently, the locusts. They are part of evolution’s great machinery. The biblical view that we are the purpose behind that machinery has caused endless problems for the ecosystem. Locusts are a problem because they consume the food that we would otherwise eat or waste. In the struggle for survival, as Joel attests, it is not always the biggest that win.
