Biodiversity Challenge – The Variety of Life

Biodiversity is the variety of life on Earth, from genes within species to whole ecosystems. About two million species have been described, but scientists estimate millions more remain unknown, especially insects, fungi and microbes.

Biodiversity is highest in tropical rainforests and coral reefs. Hotspots like Madagascar, the Andes and Southeast Asia hold many endemic species found nowhere else. Healthy biodiversity provides food, medicine, clean water and pollination.

Habitat loss, climate change, pollution, invasive species and overexploitation threaten biodiversity. Conservation efforts include protected areas, seed banks, breeding programs and the global goal to protect 30% of land and sea by 2030.
