Biodiversity is the variability among living organisms from all sources and the ecological complexes of which they are part1, ranging from birds in the air, fish in the sea, and microorganisms in the soil to genetic variety within agricultural crops and diversity of ecosystems. This variability is essential for ecosystems to function efficiently. Ecosystems provide ‘ecosystem services’ to organizations and society as a whole, including food, fresh water, wood and fibre, medicines, soil fertility, climate regulation, building materials, inspiration for scientific and technical development, genetic resources, flood regulation, and recreation facilities. There is no organization that does not make use of one or more of these ecosystem services, either directly through their own activities or indirectly through supply chainpartners.
