Class Activity: Divide learners into small groups and give each a tray with soil, leaves, and paper scraps. Each group chooses an animal (dung beetle, earthworm, pangolin, or vulture) and acts out how their creature cleans or recycles waste — for example, dung beetles bury waste, earthworms mix it into soil, pangolins eat ants that damage plants, and vultures eat dead animals to help prevent the spread of disease.
