How is climate change a threat to biodiversity?
AIt increases rainfall evenly across all regions, improving habitats, when rainfall instead becomes erratic
BIt has no effect on animal habitats, only on human agriculture, ignoring the habitat loss it causes
CIt only affects aquatic organisms, not terrestrial ones, ignoring the habitat loss affecting land animals
DIt causes adverse weather and habitat loss, forcing migration and reducing biodiversity
Explanation: Climate change causes adverse weather, habitat loss and forced migration, reducing biodiversity.
