A third of African tropical plants risk extinction: Study

The video discusses the risk of extinction faced by African plant species, with 33% potentially at risk. Researchers used IUCN criteria and developed an algorithm to assess over 20,000 species. Regions like Ethiopia, West Africa, Tanzania, and the Congo are most vulnerable, with over 40% of local flora threatened. Key threats include deforestation, climate change, and population growth, particularly affecting ecoregions in West Africa.
