This destruction of large areas of trees has: Explain what peat is and why it is important to preserve of peat. Explain why peat should not be burnt. Observe a block of peat and some peat compost. Discuss what peat is used for and why. Demo burning peat. Show images of a peat bog, peat drying and peat burnt. Explain why the destruction of peat bogs is harmful to the environment. Investigate the growth of plants in ‘peat free’ and peat based composts. Describe deforestation using evidence from images or video clips of deforestation taking place – clearing, burning, rotting and destruction of habitats. Consider the need for cheap fuel and cheap compost for food production, against the need to conserve peat bogs as habitats and reduce carbon dioxide emissions.
