      Lesson details

      Learning outcome

      I can critique the global food challenges we all face.

      Key learning points

      1. Globally, food production produces around one-third of all greenhouse gas emissions.
      2. The global population is expected to reach 10 billion by 2050, putting additional pressure on food systems.
      3. Climate change can cause extreme or unusual weather, which can affect food production and impact food security.
      4. The environmental impact of food varies, but there are principles that can be followed for more sustainable diets.
      5. Sustainable diets are good for the planet and health, balancing nutrition, environment and socio-economic factors.

      Keywords

      • Greenhouse gas emissions - gases in the earth's atmosphere that trap heat, leading to climate change

      • Food systems - a complex web of activities involving the production, processing, transport, and consumption of our food

      • Climate change - long-term shifts in temperatures and weather patterns

      • Socio-economic - the interaction between the social and economic habits of a group of people

      • Food security - having reliable access to a sufficient quantity of affordable, nutritious food

      Common misconception

      Biodiversity is not important in growing food, only the plants growing are important.

      Biodiversity is important in growing food by promoting a healthy and balanced ecosystem, e.g. encouraging insects and birds to live near fields can help keep pests under control.

      Teacher tip

      While dealing with global issues, engage and motivate pupils by introducing these themes within familiar (local) contexts. For example, selecting local foods (saving food miles), reducing food waste in the home, and making pragmatic changes to diets based on the Eatwell Guide.
