Today is La Hora del Planeta when people are asked to consider their impact on our planet and, a s symbol of their willingness to look after our world, put out their lights from 8.30pm local time for an hour.
La Familia Tellerín and WWF have produced a little video to promote this:
You could use this video to practice using Se debe and No se debe

And then Peppa Pig has added her voice, offering advice (and there’s a colouring sheet too!):
I also liked the video below from WWF that explains the initiative in a more detail for older learners.
¿Quién apagará las luces a las ocho y media esta tarde?
