Anyone who has been hanging around for any amount of time over here knows that I am a major fan of Bitmoji Boards as an edtech way of sharing resources.
Here is a great that I ran across for Earth Day, created by @MissHecht. You can find this and approximately 80 more of her Bitmoji creations at her LinkTree Account. She has one on Recycling, Biomes, and Animal Adaptations too, which might also serve your environmental needs here this Earth Day. You can also buy her (aka Bridgette) a cup of tea as a way of saying thanks, or follow her Creative Teaching with Miss Hecht page on Facebook.
