Dianna Cohen

 Dianna Cohen''' is an American visual artist and activist. She is the CEO and co-founder of the Plastic Pollution Coalition, an advocacy group and social movement organization which seeks to reduce plastic pollution.

Early life and education
Cohen grew up in Los Angeles. Her father was a filmmaker, and her mother the director of the Los Angeles Free Clinic. She attended UCLA, where she studied biology before shifting her major to art.

Career
Following her graduation, Cohen began working in collage, initially using deconstructed brown paper bags, and later incorporating plastic. Her first solo exhibition of the bag series was in 1994.

After eight years of working with plastic bags, Cohen realized the plastic was degrading. In a 2015 interview she said: “At first I got excited because I thought that it meant the plastic bags were ephemeral and organic like us, and that they had a finite lifespan.”  In researching the subject, she discovered that "plastic photodegrades or heat-degrades by breaking apart, but does not disappear." In 2009, after learning about the Great Pacific garbage patch, she founded the Plastic Pollution Coalition (PPC) with her sister, Julia Cohen, Manuel Maqueda, Daniella Russo and Lisa Boyle.

In 2010, Cohen was invited to give a TED Talk on Mission Blue in the Galapagos Islands. Entitled “Tough Truths About Plastic Pollution,” it has been viewed more than 1 million times. She was named Environmentalist of the Year by SIMA in 2019.

Personal
Cohen and her partner, Jackson Browne, live in Los Angeles. They were co-executive producers on the 2020 documentary The Story of Plastic. She has surfed since 1996.
