(CNN)Earlier this week, I wrote a column for CNN Opinion about the climate cost of beef production — arguing we have to cut back on steak and hamburgers to avoid dangerous warming.

In response, Torben Ørvad Jensen, a reader in Denmark, asked why we don’t substitute a fairly unconventional protein source — grasshoppers — for cattle.

Would that help reduce human contributions to global warming?

“How can we get the governments around the world to see, that one of the the answer to both famine and climate change, is breeding new kinds of livestock like grasshoppers?” he asked.

“Insects are not the answer to everything,” he added, “but its one of the great changes that could be fundamental to fighting climate change in the long run.”

I’m not sure about the “convincing world leaders” part, but there is some research to show Jensen may have a point about insects having smaller carbon footprints than other protein sources, especially beef, which has an outsize contribution to global warming.
