Waste Not, Want Not

Does Wasting Food Contribute to Climate Change?

Elementary, Middle, Secondary

Description

Waste Not Want Not is part of a compilation of local climate research from science heroes across Canada and climate actions that students can complete at home, in class or in the community. 

In this research feature, students learn how wasting food contributes to climate change. Wasted food may not come to mind when you think of major contributors to climate change, but it has a significant impact that can go under the radar. This impact is felt at every stage of the human food system, from farm to table.

As our planet's population increases, so does the demand for new food to be produced, increasing the need for land and water resources. This can lead to the destruction of natural habitats, such as deforestation, making the impacts of climate change even worse.

Students will:

  • Meet the local science hero of this edition, Farrah So, a Food Waste Researcher
  • Learn about the research as it relates to food waste management
  • Learn ways to fight food waste
  • Participate in a compost bin activity
  • Learn to make a difference in the amount of food waste with some simple changes
  • Learn more about climate change and how to take action

General Assessment

Recommendation of how and where to use it

This resource complements Grade 5-8 Science and Social Studies units exploring the causes and consequences of climate change and the connections between humans and global sustainability issues such as food waste, habitat loss, and deforestation. To extend the learning process, students could create a shared table in the school cafeteria to place unwanted food items that are intact or unopened. They could also create brochures with tips for sustainable food shopping for friends and family members. Older students might complete a community awareness project about food waste.  The class could make a book about the amount and types of food often thrown away and recipes for using items like overripe produce.
