Major causes of biodiversity loss (the "evil quartet") include
- A
Excess rainfall, increased UV exposure, soil enrichment, atmospheric warming (and ozone)
- B
Genetic drift, balancing selection, gene flow, mutation accumulation (and inbreeding)
- Ccheck_circle
Habitat loss, invasive species, pollution, overharvesting (and climate change)
- D
Native predation, mutualism breakdown, parasite cycles, disease emergence (and exclusion)
Explanation
These anthropogenic drivers, plus climate change, account for most biodiversity decline.
