Thanks to the Public Broadcasting Service of the USA for the video above and these links to sustainability-focused terminology, in this case related to Food Waste:

Nearly 40 percent of the food we grow, distribute, put on store shelves then ultimately buy as consumers never gets eaten. It’s called food waste and people are doing something about it by gleaning, composting, and learning to eat from head to tail to eliminate waste.

Food Terms

Food waste
“Forty. That’s the percentage of food in this country that never gets eaten, or that’s grown and never comes to market. It’s the food we distribute that never reaches a destination or sits on grocery store shelves without finding a consumer. And it’s food consumers buy but never eat. “

Gleaning
A type of food rescue that involves collecting leftover fruits and vegetables from farms, with the food usually donated to school lunch programs, non-profits and food banks. By performing food rescues, communities can help re-distribute food that would otherwise go wasted, helping to turn food insecurity into food security.

Compost
Turning food waste into valuable nutrients that can improve soil and feed plants.
