Plant-based Hollywood

Plant-based has been extremely popular in Hollywood recently, as multiple award ceremonies have moved to ditch animal products from their menu in a bid to help the environment.

Among them was the recent Screen Actors Guild Awards, which released a statement about the decision saying: "As part of the show's long-standing commitment to sustainable practices, the 26th Annual Screen Actors Guild Awards will feature a plant-based menu at its ceremony on Sunday, January 19...

"The SAG Awards has also partnered for multiple years with non-profit environmental organizations such as American Forests. For the 25th Anniversary of the SAG Awards, American Forests planted 25,000 trees across the U.S. in a collaborative effort to improve the quality of air, water, and wildlife habitat."
