Coca-Cola might be the world’s most recognizable brand. But what would it be with only half the name?

       An Indigenous business in Colombia, acting, it says, “in defense of the coca leaf,” is asking the government to revoke the beverage giant’s century-old trademark on the word “coca.”

       The coca plant, which is used to produce not only Coca-Cola but also cocaine, is a major legal crop in several South American countries.
