      Climate change and human health

      Lesson details

      Learning outcome

      I can explain how climate change affects human health and the spread of diseases.

      Key learning points

      1. Human health is affected by nutrition, fresh water availability, pathogens, and environmental conditions
      2. Climate change affects fresh water availability and the growth of crops
      3. Heat-related ill health, malnutrition and communicable diseases are becoming more common as a result of climate change
      4. The spread and prevalence of diseases are influenced by climate
      5. Communicable diseases (e.g. malaria) may spread more easily and into new geographical areas due to climate change

      Keywords

      • Pathogen - a virus, bacterium or other microorganism that causes disease

      • Malnutrition - the lack of proper nutrition due to not having a balanced diet

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

      • Prevalence - how widespread something is, especially a disease or pathogen

      Common misconception

      Thinking that climate change affects the weather, but not human health.

      This lesson explores direct and indirect impacts of climate change on human health.

      Teacher tip

      Task B can be done as a physical card sort activity by providing pupils with printed word cards to build a concept map.
