The terms Anthropocene and Homogenocene are frequently used to describe our current epoch, which is characterized by strong human impacts on the environment. One defining feature of the Anthro- or Homogenocene is biodiversity loss – experts say we are heading for Earth's sixth mass extinction. A crucial weapon in the battle against threats to biodiversity is education, particularly biodiversity literacy. Raising awareness of the social and environmental value of biodiversity, providing education on the concept of biodiversity, and promoting the ability to act may lead to active and responsible citizenship. We developed a biodiversity education teaching unit to promote biodiversity literacy through formal education. To make the topic of biodiversity tangible for students, our approach involves them in a citizen science project and uses the forest ecosystem to illustrate the relations between economic, ecological, and social aspects of biodiversity.
