- In whatever way you define biodiversity, humans are part of it.
- Humans obtain services from ecosystems to survive, make a profit, or increase their own well-being. In doing so, little effort is made to ensure long-term (inter-generational) well-being or equity; the focus is on maximising short-term well-being.
- To extract services, humans often adapt and simplify existing ecosystems or replace existing ecosystems with simpler ones. Humans thus increase their well-being by reducing the diversity within and between ecosystems; that is, by reducing biodiversity.
