It's up to us whether the environment in which we live is clean and healthy and worthy of passing on to future generations or not. That's the lesson this song imparts. The marriage of Latin and EspaƱol flavors in this tune is infectious and encourages passion. The song includes rhythmic hand claps, which really add to the overall excitement.
The vocals can either be simple or not, as you prefer. The simple version is unison (with or without claps). The more challenging version would include parts 2 and 3, which enter the second time. The parts sound very cool together, and for older students in particular offer some great musical moments. Isolated rehearsal tracks for part 2 and part 3 are included in the kit, as is a unison version as well as an a cappella version with claps. (from Music K-8, Vol. 23, No. 4)
