Climate change and food production

I can explain how food production is affected by and contributes to climate change, and how changes in diet can help to limit climate change.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Food production is at risk due to global warming and climate change
  2. Climate change makes extreme weather events more common, and this makes it more challenging to produce food
  3. Emissions of greenhouse gases from various stages of food production add to the carbon footprint of foods
  4. Changes in our diet can help us reduce emissions from food production and limit climate change
  5. Comparing emissions data for different diets helps us understand the impact of food choices

Keywords

  • Global warming - an increase in Earth’s average surface temperature

  • Greenhouse gases - gases in the atmosphere that keep it warmer than it would be without them

  • Emissions - releases of greenhouse gases into the atmosphere

  • Climate change - a long-term shift in weather patterns

  • Carbon footprint - the calculated total amount of greenhouse gases emitted by an activity

Common misconception

Thinking that what we eat has no impact on climate change, or that all foods have roughly the same impact.

This lesson explores in detail the impacts of different foods and dietary choices in terms of their carbon footprint of greenhouse gas emissions.


To help you plan your year 9 science lesson on: Climate change and food production, download all teaching resources for free and adapt to suit your pupils' needs...

Pupils may not feel they have much agency in being able to change their diets to help limit climate change. This issue is addressed in Task B through the idea of communicating with parents as an example of positive action.
