La obsesión de EE. UU. con el aguacate está acabando con los bosques mexicanos
La deforestación ilegal para cultivar el preciado fruto apunta a un comercio sangriento de exportación que involucra amenazas, secuestros y asesinatos.
Yes, I think it comes from the same rule. Estados Unidos is plural, so the abbreviation is doubled single letters. Sometimes English does this too (pp. for pages or §§ for sections). There are other examples in Spanish too.
americans are a disaster on this planet: drive a pick-up truck, grow lawns, eat exotic fruits, smallest state to state trip is done by airplane, and probably would choose 'drill baby drill' Trump in the next elections. Tbh the rest of the world need to have a say on US elections too, like maybe allow europeans to vote too ?
