The Biodiversity theme allows students to explore the diversity of life on Earth and understand the complex interactions between humans and the environment. The theme is broad enough to allow students to engage in a wide range of outdoor-learning activities.


The term “biodiversity” (from the Greek “bio”, which means “life”), refers to the diversity of living things in terms of species, ecosystems and genetic diversity. Conserving biodiversity both from a geographical perspective and over time has become one of the major issues in sustainable development.


Factors such as population growth, an increasing need for travel and ever-higher levels of consumption mean that people are constantly putting increasing pressure on ecosystems and steadily reducing biodiversity. Researchers are now talking about the sixth major extinction, highlighting the disappearance not only of terrestrial species but also aquatic organisms and plants. Yet even the most common species, which are not directly under threat, are also seeing a massive decline in their populations, threatening the fragile balance of ecosystems.


Locally, the creation of natural spaces for some threatened species, such as forming pools for toads and frogs, or making piles of branches or compost heaps for reptiles, etc., have helped smaller species to return. The creation of a garden is also a great initiative to promote biodiversity, to allow insects to come back and to think about the origin of our food.

Our consumption choices are critically important to our impact on ecosystems.  Encouraging more responsible consumption by prioritising local producers who respect the environment, avoiding waste and preventing it from being discharged into the environment are examples of simple, local actions that have a decisive impact at the global level.


Primary level: Sciences, Biology: Observe the various species living in the school’s environment (vegetal and animal)

Middle level: Biology: Learn about plants and animals benefitting from each other’s presence (using a memory game)

Secondary level: German/Italian/Spanish/…: Learn in another language the names of the plants and animals observed on an expedition, or even make a little presentation about them
