Biodiversity can be described as the variety of life, usually on some specific scale. This can be within your back garden, a droplet of water or even the entire earth. All living organisms on that scale are included, from animals and plants to microorganisms. And all those organisms play one or more roles there, for example as a decomposer, pollinator or food source.

Unfortunately, biodiversity is globally under pressure due to human activities. According to the International Union for Conservation of Nature (IUCN), more than 35,000 species of plants and animals are threatened with extinction. Scientists at Utrecht University study biodiversity in a variety of research groups, and they are eager to share their expertise.
