Mexico’s disappearing mezcal worms

Across Mexico, and in many world capitals, people are increasingly raising a glass of mezcal, a traditional Mexican liquor.

Connoisseurs of the strong drink say it tastes best when served the traditional way– with a worm in it.

But the worm population is being pushed into decline, due to the drink’s growing popularity.
