Biodiversity – Setting the Scene
summary
Biodiversity breaks into three concrete layers: genetic diversity, species diversity, and ecosystem diversity, each needed for pollination, carbon sequestration and fertile soils. Current facts: about 150 species every day go extinct, a patch of rainforest the size of a soccer pitch every five seconds disappears, and background extinction is accelerated by ~1,000×; humans already use roughly half of the planet’s habitable land. Five main drivers are land‑use change, overexploitation, invasive species, pollution and climate change, and companies across food, finance, fashion and hospitality start adapting because ecosystem loss breaks supply chains and food security.
