Competition from invasive species
Global climate change
Population growth and over consumption
Unsustainable use of natural resources.
Consequences of loss of Biodiversity
A loss of ecosystem services- Protection of water resources, nutrient storage and cycling, Pollution breakdown and absorption
Loss of genetic diversity- Genetic diversity allows species to adapt to changing environmental conditions and stresses.
Reduced food security.
Preservation of Biodiversity
