A pile of food waste in a container, featuring various items such as cheese, tomatoes, orange and banana peels, lettuce, apples, a tin can, bread, and a bottle of milk.
A lot of food is wasted every day all around the world for many different reasons. Nearly one-third of all food produced in the world goes to waste. How much food is that exactly?
Humans waste an estimated 1.3 billion tons of food every year. That is roughly the same weight as 217 million elephants!
When we waste food or don't use it all up, it can make it harder for everyone to have enough food to eat. This can also make food cost more because there's less of it available.
While many people on Earth experience food insecurity, the amount of food waste produced is roughly enough to feed the entire planet. Food insecurity is a term used when individuals do not have access to enough safe to eat and nutritious foods to meet their daily needs. It is estimated that one in every four Canadian children experience food insecurity.

The climate cost of food waste
Wasted food is not just a social injustice , it is also an environmental hazard . When food gets thrown out, all the human effort that goes into it, as well as the water, fuel, and materials used to grow, transport, and pack that food is also wasted.
Student Remy is talking.
Student Remy is saying:
“So that means humans are using land, water, and fuels to produce a lot of something, and then half of it ends up being thrown away?”
Teacher Chelsea responding to learner Remy's question.Teacher Chelsea says "Yes. Land is cleared, water is used, and fuels are burned to produce food that sometimes doesn't make it to being eaten. Also, the wasted food releases a gas called methane while it rots, and methane is one of the greenhouse gases that is causing warming of our planet's atmosphere."

- “Wasting food is bad for the environment because you’re wasting a ton of resources, which helps climate change keep going,” said Asha. “All the greenhouse gases that go into [making something], all those people’s hard work, it just ends up in the trash.”
- “See what’s being thrown in the garbage and think of creative ways that you could use it in a soup, stew, chili or a beverage,” said Gordon.
- “Just because a piece of fruit or vegetable is imperfect doesn’t mean it’s useless. Just cut off the bad bits and chop it up.”

Creative uses for food waste
There are many creative ways that people in Canada and all around the world are reducing food waste and living more sustainably.
Explore the following video clip from the TVO Kids show Green Squad to learn about Vikram and his family and how they are adapting cultural practices from India in their home in Canada.
Were you surprised by any of the items that Vikram and Lisa sorted for composting?
What can and cannot be composted depends on where you live. Some individuals manage their own composting, while some communities and regions have recycling and composting services that collect waste and deal with it for them.
Every waste management service has their own rules and guidelines for items that can and cannot be composted depending on the facilities and technology they have available to them
It’s important to check with a trusted adult about what composting can be done in your community. If you’re not sure, together you could do a little research to learn what items can be easily composted in a home, school, or business and which items might be able to be composted using a local waste management service!
Pause and Reflect
Pause and reflect
In a notebook or using another method of your choice, answer the following questions:
Do you have composting available?
If so, what items listed in the video do you think may or may not be compostable in your community?
Reducing our carbon footprint
Indigenous Peoples throughout the world have long studied and taught their younger generations about the interconnectedness of all things on the Earth.
Indigenous communities have a deep understanding of their local environment as they have lived off, and learned from, the land for generations. The knowledge that derives from this understanding is called Traditional Ecological Knowledge or Traditional Knowledge.
Indigenous Peoples have always observed the changes in their environments and through observations, responded in ways that aim to protect the Earth for future generations.
Historically, not all people have considered this perspective and understanding and now our planet is changing at a rate faster than many life forms can keep up with.
How can we take action to reduce our carbon footprint and help the sustainability, or long-term health, of our planet?
One way is by trying to give back to the land and growing our own food. This helps us remember our close relationship to the land and how we are dependent on it for our survival.
Check out the following clip from an episode of the TVO Kids show Green Squad, where 13-year-old Malik visits a community garden near his home and learns how to create an indoor garden in his apartment.
Pause and Reflect
Pause and reflect
What did you learn by exploring Malik’s experience in the video? What are two actions you would recommend for someone to take to reduce their food waste or carbon footprint?
Record your thinking in a notebook of using another method of your choice.
When people are able to eat food grown locally by farmers or in home, backyard, or community gardens, this helps to reduce our carbon footprint. Locally raised foods don’t have to travel long distances and they use limited packaging. Gardens also help add greenspaces to urban areas. Gardens can be private or shared, such as a community garden. Gardens can exist anywhere such as in backyards, on balconies, or in sunny rooms indoors.
Exploring food recovery
When planting or gardening is not an option, it is important to consider other ways to reduce food waste and help the world.
When food is saved and shared instead of wasted, humans and the Earth benefit. Saving food that might have been wasted and sharing it with people who can use it is called food recovery.
Press the following tabs to explore some of the innovative food recovery solutions that exist in Canada.
Rescues food from farmers, stores, and restaurants and distributes it to organizations like food banks, shelters, and school food programs.
Companies like Odd Bunch, Second Life, and Peko Produce rescue fruits and vegetables that are oddly shaped or coloured making them “ugly” or not visually appealing enough to be sold in grocery stores. They then include these foods in grocery subscription boxes that are sold to Canadians.
A Los Angeles organization that rescues fruits and vegetables from backyard trees, community orchards, and farms and distributes it to people experiencing food insecurity.
An app that helps shoppers find deals and discounts at their local grocery store on food that is near its sell-by date or needs to be eaten soon.
A Toronto non-profit organization that collects excess food that would otherwise go to waste from restaurants, grocery stores, farms, and food producers, and then transforms it into healthy meals. They sell foods and meals in a pay-what-you-can store, serve soup to college students twice a week, and they stock free community fridges across the city.
An app that allows restaurants, hospitals, and other organizations to call a driver to pick up food that is going to go to waste. The food is then delivered to places that need food or to the homes of people experiencing food insecurity. They also visit neighborhoods with their free mobile grocery store and have free grocery shops located inside schools to serve students and their families.
"Ugly Food Companies" are food manufacturers who buy fruits and vegetables that aren’t "pretty" enough to be sold in grocery stores and use them to create their own products. A few Canadian examples include Outcast Foods who make plant-based protein powders, Pretty Ugly Company who makes salsa and corn chips, and Loop who makes juices, smoothies, and sodas.
