Now that COP28 has concluded, it’s time for a quick climate-change quiz. See if you can identify the climate hero in the scenario below:

Jared and Annette arrive at a potluck, each bringing a mixed salad with the same ingredients. By a strange coincidence, they’re also wearing identical Christmas sweaters. They compare notes, and it turns out Annette’s salad ingredients were all bought from Vermont farmers, while Jared’s are supermarket ingredients shipped here from California, Mexico and Chile. Annette’s sweater was knit by a local crafter using Vermont wool. Jared’s came from Walmart, and was produced in a Chinese sweatshop using electricity from a coal-fired power plant.
