"Nuestro Mundo" ("Our World") is a Plaza Sesamo song about respecting nature, performed by Abelardo, Lola, Pancho and some kids. They sing over scenes of animals, plants and the gang planting trees and cleaning litter.

Scenes from the song were later used during the performance of "We Are All Earthlings" in episode 828.

Ocassionally, the song was shown during the end credits of the show.
