What are the causes of biodiversity loss?
The five principal causes of biodiversity loss are known by the acronym of HIPPO: Habitat loss Invasive species Pollution Population growth (and increased consumption of goods and services) Over-exploitation. Climate change is an emerging threat to biodiversity that will change temperature and water cycles, create pathways for new pathogens and insects, and alter ecosystem function. In Washington, scientists believe the most serious threats to biodiversity are habitat loss, invasive species, population growth, and climate change.
