Lesson details

Key learning points

  1. Growing crops to feed animals and humans requires significant land use
  2. Converting land for agricultural use is one of the major causes of deforestation
  3. Deforestation results in habitat loss for many species
  4. Conversion of land for agriculture is a major cause of habitat loss and biodiversity loss
  5. Mitigation strategies include changing diets and positive land use change (e.g. reforestation and rewilding)

Keywords

  • Agriculture - using land to raise farm animals and grow crops to feed humans and farm animals

  • Deforestation - the removal of trees, often to use the land for agriculture or building

  • Habitat - the place where an organism lives, which provides the organism with food, shelter and a place to reproduce

  • Biodiversity - the range of different living organisms (species) in an ecosystem

  • Ecosystem - all the living organisms in a place interacting with each other and their non-living surroundings

Common misconception

Thinking that agriculture just means growing crops.

The lesson explores the idea that agriculture also includes using land to rear animals, and that this has destroyed more habitat than using land to grow crops.

Before starting this lesson, pupils should be familiar with some key ideas in ecology such as what is meant by the terms 'habitat', 'species' and 'ecosystem', and the interdependence of species (e.g. through food chains and pollination).
