"A Secret Weapon In Agriculture’s Climate Fight: Ants"

"Ants — yes, ants — could protect apples, nuts, cocoa, and other beloved crops from disease and climate change."

"The ant scurries along on six nimble legs. It catches up to its peers, a line of antennaed bugs roaming the winding surface of a tree, perpetually hunting for food. While doing so, each unknowingly leaves antibiotic microorganisms secreted from its feet.

That trail of tiny footprints, indiscernible to the naked eye, is remarkably effective at protecting the tree from pathogens and pests. That makes ants, in the eyes of Ida Cecilie Jensen, a legion of unlikely warriors — one humans should consider enlisting in the fight to grow food in a warming world. “Ants are a Swiss Army knife,” said Jensen, a biologist who studies the symbiotic relationship between ants and agriculture at Aarhus University in Denmark. “Kind of like a multitool for farmers.”

With an estimated 20 quadrillion ants on Earth at any given time, the bugs are found just about everywhere on the planet. They are also among the species that humans, which they outnumber at least 2.5 million to one, have most in common with. Ants have extraordinary collective intelligence, their colonies weaving robust community networks and dividing labor. The social insects even wage war with one another and build complex agricultural systems."
