Marielle’s lawsuit reflects a broader trend among consumers—especially young ones—favoring nondairy alternatives. Teens and young adults in Generation Z grew up ordering milk alternatives at coffee shops and toting water bottles everywhere. Turned off by the no-fat and low-fat milks served at school, worried about the climate, and steeped in the criticism of the dairy industry they see on social media, many young people never embraced milk, even though their parents may have.
Last year, Generation Z (born from 1997 to 2012) bought 20 percent less milk than the national average, according to the consumer research company Circana.
“[Dairy] milk on its own is something that most of my peers don’t drink,” Marielle says. She’s surveyed hundreds of students at her school on their milk preferences, “and every single one of them wanted to have plant-based milk in our schools.”
Both the U.S.D.A. and the Los Angeles Unified School District declined to comment on the lawsuit.
“When it comes to statutes regarding fluid milk substitutes, the U.S.D.A. is limited by law, and any statutory changes would require legislative action by Congress,” a U.S.D.A. spokesperson said.
Already the lawsuit has gained national attention. Marielle hopes it will shed light on the benefits of plant-based milk. But she also hopes the lawsuit will bring young people more freedom to fight for the issues that matter most to them.
“In order to be able to change the world, we need to be able to have important and even controversial conversations without this sort of silencing or canceling,” Marielle says. “People need to be able to express themselves, and without that. . . we’re not going to advance as a society.”
