Anthony Bourdain is raising awareness about a global issue in the trailer for Wasted! The Story of Food Waste.

The prolific chef turned TV personality produces, narrates and appears in the preview for the documentary, which explores the major yet widely unknown sources of food waste, from the farming and fishing industries to supermarket chains and school cafeterias. A lot of what's tossed out is due to lack of demand from the public — until it's trendy, that is.

Anna Chai and Nari Kye co-direct the eco-minded movie, which also features appearances by chefs Dan Barber, Mario Batali, Danny Bowien and Massimo Bottura. The Rockefeller Foundation, which last year made a $130 million commitment to cut food waste in half by 2030, supported Zero Point Zero Films and Bourdain to create the doc. It debuted earlier this year at the Tribeca Film Festival.

"I'm not an activist, but the intent of this film aligns with something that's very much personal," stated Bourdain. "I came up in kitchen regimes where you live by an absolute rule of using everything and wasting nothing. And of course, as a traveler, I see again and again how circumstances force people to cook incredibly well with often very little food available to them. One film isn't going to cure all of society's ills, but if a few people start thinking about what they're eating for dinner in a different way or think twice about throwing out what is often the best stuff, it's a good day."

Neon's Super LTD will release Wasted! in select theaters and on VOD on Oct. 13.
