Debby Lee Cohen, Who Helped Prune Plastic From Schools, Dies at 64

As an artist who liked to play with scale, Debby Lee Cohen created monumental pieces, like the giant puppets she designed for Manhattan’s annual Village Halloween Parade, as well as miniatures, like the tiny forest she once made for a work by the interdisciplinary artist and compose Meredith Monk, with whom she often collaborated.

A decade and a half ago, she became a plastic activist when she learned the scale of waste in New York City’s public schools.

Her daughter Anna, then in second grade at a school in the East Village, had announced that she was boycotting lunch after seeing an exhibition on climate change at the Museum of Natural History that included a diorama of polar bears atop a mountain of what she recognized as her school’s lunch trays. It was then that Ms. Cohen learned that school lunches were served on foam trays — and that the city’s more than 1,800 public schools were using and throwing out at least 800,000 of them daily.

Ms. Cohen, an artist, animator, performer, puppeteer and environmental activist whose campaign to eliminate foam trays from New York City’s public schools paved the way for similar bans in the city and state — and who taught students how to advocate for themselves at school and at City Hall — died on April 7 at her home in Manhattan. She was 64.

The cause was colon cancer, said her sister, Ellie Cohen.

In 2009, after her daughter’s school lunch boycott — which she solved in the short term by making her daughter’s lunches herself — Ms. Cohen looked for organizations that were dealing with the tray issue. There were none. But she found like-minded parents who were also working to reduce the staggering amount of plastic waste in their children’s schools, and they banded together to push for citywide action.
