Rhino poaching persists despite a slight decrease worldwide over the last three years, driven by relentless demand for their horns in East Asia, according to a recent report by TRAFFIC and the IUCN. Three of the world's five rhino species are still in decline, the report finds, with white rhinos in Africa dwindling to an almost two-decade low. Greater one-horned rhinos in India and Nepal are recovering well, while Indonesia's Javan and Sumatran rhinos - both critically endangered species - continue to teeter on the brink of extinction. Experts say increased intelligence and cross-border cooperation, stronger community programs and enforcement, and stricter sentences for traffickers are needed to save these megaherbivores.
