Since Zach's passing, the Zach Sobiech Osteosarcoma Fund has raised more than $2.2 million to aid research efforts to treat osteosarcoma. While watching the Disney+ movie is great to raise awareness, there are more direct ways you can support the fund.

A simple way you can directly support the fund is by streaming or downloading the song "Clouds," as all of the revenue earned from the song will be donated directly to the fund. 

Laura says you can also buy her memoir, Clouds: A Memoir, and host a book club with your friends or buy the Clouds merchandise. A portion of the profits from all of these sales goes directly to the fund.
