      How is plastic damaging the environment?

      Lesson details

      Learning outcome

      I can describe the environmental impacts of plastic pollution and the challenges in reducing plastic use and propose strategies to reduce plastic waste.

      Key learning points

      1. Plastic pollution harms ecosystems, oceans, and wildlife by causing ingestion and entanglement.
      2. It can take thousands of years for plastic to break down and so it accumulates in landfills and natural environments.
      3. The convenience, affordability, and durability of plastic make it difficult to replace.
      4. Strategies to reduce plastic waste include recycling, cutting single-use plastic and policy change.

      Keywords

      • Plastic - an artificial material mostly made from oil or natural gas which can be moulded and shaped

      • Pollution - when harmful substances or waste are released into the environment, causing damage to nature and living creatures

      • Recycling - the process of collecting and turning used materials into new products

      • Sustainable - using resources and making choices in a way that does not harm the environment

      Common misconception

      There are no alternatives to plastic.

      There are lots of alternatives to plastic that are easier to break down or recycle and therefore have less of an environmental impact, for example, glass and metal.

      Teacher tip

      Encourage pupils to consider how their actions can reduce plastic waste and discuss ways they can influence those in power, like local councillors, to support policy changes.
