What Goes In Must Come Out
Creating and consuming food requires a wide variety of inputs and outputs, including some that are wasteful and harmful to the earth.
About the Activity
In this activity, you will learn that modern food systems require major inputs (such as water, labor, fossil fuels) and produce major negative outputs (such as greenhouse gases, air pollutants, wastewater, and solid waste). You’ll come to see that modern food systems can be wasteful and that making informed food choices can eventually contribute to impactful changes.

The only supply you need for this activity is the interactive content on this page!
Use the interactive module here to learn about the inputs and outputs of modern food systems – like how an apple becomes a breakfast bar.
Bonus questions to inspire wonder.
- Why does what we choose to eat have an impact on the environment?
- How should consumers help reduce negative outputs in modern food systems?
- How would thinking of food as a system with six activities, many inputs, and various outputs help you support a food system to become more sustainable?
Investigate and Explore
Take what you've learned to the next level to learn more and explore the possibilities.
People talk a lot about ‘processed foods’ and how their creation and evolution in the last 60 years changed how the world eats. Now that you’re familiar with this idea, think about all of the things in your home that you grandparents or great grandparents never would have eaten growing up, like cereal, protein bars, boxed macaroni and cheese, and other things you’re probably familiar with. Then look at what is in your house that they would have eaten, like fruits, vegetables, and milk. Imagine what they would think if they could set foot inside your home today!
