Ecological and social footprint

GCSE Design and Technology revision notes, key terms and practice questions.

Ecological issues

  • Getting materials can damage the environment: deforestation for timber, mining for metal ores, drilling for oil (for polymers), and farming for cotton, which uses a lot of water and pesticides.
  • Products travel long distances (product miles), which burns fuel and adds to their carbon footprint.
  • The carbon footprint is the total amount of greenhouse gases produced by making, using and disposing of a product.

The 6 Rs

  • Reduce: use less material and energy.
  • Refuse: don't use materials or products that are bad for the environment.
  • Reuse: use a product again, for the same or a new purpose.
  • Repair: fix products instead of throwing them away.
  • Recycle: reprocess materials to make new products.
  • Rethink: design products in a new way to be more sustainable.

Social footprint

  • Working conditions: some products are made in factories with long hours, low pay and unsafe conditions.
  • Fair trade and ethical sourcing help workers get fair pay and safe conditions.
  • Products can affect communities, such as a new factory bringing jobs but also pollution.
