Loss of biodiversity
- The colonization of tropical Pacific Islands by humans is said to have led to the extinction of more than 2,000 species of native bird.
- The IUCN Red List (2004) documents the extinction of 784 species.
- Some examples of recent extinctions include the dodo (Mauritius), quagga (Africa), thylacine (Australia), Steller’s Sea Cow (Russia) and three subspecies (Bali, Javan, Caspian) of tiger.
- Loss of biodiversity in a region may lead to
- Decline in plant production
- Lowered resistance to environmental perturbations such as drought
- Increased variability in certain ecosystem processes such as plant productivity, water use, and pest and disease cycles.
