What Goes In Must Come Out

Creating and consuming food requires a wide variety of inputs, while also producing 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 gasses, 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.

Grades: 7-10

Investigate and Explore
Take what you've learned to the next level to learn more and explore the possibilities.

As the global population continues to grow, our food systems are facing a great challenge to meet the increasing food demands of billions of people. Even though the earth is large, not every land is suitable for growing food. Plus, traditional agriculture consumes a lot of energy and has many negative impacts on the environment. Fortunately, scientists and researchers are finding new, sustainable ways to increase food production given limited land and resources.

We encourage you to do some exploration to find some examples of food production innovations around the world and learn how these new technologies or approaches contribute to food systems sustainability. You’ll be amazed at what you find.
