Sustainable Food Practices

Sustainability is a critical theme in the modern food landscape. This topic explores the environmental impact of our food choices, including carbon footprints, food miles, and the problem of food waste. Students learn about Singapore's '30 by 30' goal, to produce 30% of our nutritional needs locally by 2030, and how supporting local produce contributes to food security.

Activity 01

• Inquiry Circle
• 50 min · Small Groups

Inquiry Circle: The Food Mile Map

Students look at the 'Country of Origin' on various supermarket items and plot them on a world map. They calculate the 'food miles' and discuss the environmental cost of importing fresh produce from far away.

How does food production contribute to climate change?

Activity 02

• Formal Debate
• 45 min · Whole Class

Formal Debate: Local vs. Organic

Students debate which is better for the environment: buying local produce that uses conventional farming or buying organic produce that has been flown in from overseas. They must consider carbon emissions and soil health.

What are effective ways to reduce food waste at home?

• Analyze
• Evaluate
• Create
• Self-Management
• Decision-Making

Activity 03

• Simulation Game
• 40 min · Small Groups

Simulation Game: The Zero-Waste Kitchen

Groups are given a list of 'leftover' ingredients (e.g., broccoli stalks, overripe bananas, sour milk). They must come up with a creative recipe to use these items instead of throwing them away.

Why is Singapore's '30 by 30' food security goal important?

A few notes on teaching this unit

Watch Out for These Misconceptions

• Food waste isn't a big deal because it's biodegradable.

  In landfills, food waste produces methane, a potent greenhouse gas. A 'composting vs. landfill' simulation helps students understand the environmental impact of improper food disposal.

• Singapore is too small to produce its own food.

  High-tech vertical farming and aquaculture are making the '30 by 30' goal possible. A 'virtual tour' or research project on local high-tech farms can help students see the potential of urban agriculture.
