17 Resources for Teaching About Food Waste

“Every day, we’re teaching kids that food is trash.” ~ Jonathan Bloom

Our school food systems in the US are not set up to minimize waste or encourage healthy habits.

Students are often rushed at lunchtime, may have unappetizing food options, may be given (or take) much more food than they’ll eat, and then they often only have the option to throw their leftovers (and sometimes their single-use plastic trays) in the trash.

According to a 2018 study, worldwide we’re wasting more than 30% of our food (about 1.6 billion tons), and that number could increase to 2.1 billion tons annually by 2030.

Another 2018 study shows that young adults, ages 18-24, tend to waste more food, in part because they don’t understand the impacts of food waste.

And the impacts of such waste aren’t just hurting hungry people and bolstering dysfunctional systems.

A 2013 FAO report shows that there is a significant “environmental footprint of food wastage” that affects “climate, water, land and biodiversity.” Food waste also negatively impacts wild animals and farmed animals.

According to the book and website Drawdown, which looks at solutions to reduce the impacts of global warming, reducing food waste is #3! So the potential to do a lot of good is significant.

Since food is a daily part of our lives, food waste is a valuable issue to explore with students, so that they can develop and enact meaningful habits and solutions.

Here are 17 resources to get you started on teaching about food waste.

(Note that most of these resources leave animals as individuals out of the circle of concern.)
