global biodiversity
Earth's living variety
Global biodiversity refers to the total variety of life on Earth—the sum of all species, their genetic variation, and the ecosystems they form.
The term frames biodiversity as a planetary resource requiring international cooperation: Global biodiversity is declining at unprecedented rates.
Conservation efforts often invoke it when discussing species loss, habitat destruction, or the interconnectedness of life across borders.
