A Google animation for 2021 Earth Day about planting something for the next generation

As the song plays, a new instrument is introduced to match whenever a new character appears on screen. Starting with a simple pizzicato, before blossoming into piano with a sparkling, cascading delay effect. This progression from one lonely instrument to an orchestra helps reinforce the idea that planting a tree is an action that will last throughout the years, growing eventually into a forest.
