Since 1970, 4,392 mammals, amphibians, birds, fish and reptile species’ population sizes declined by 68 percent, according to a World Wildlife Fund report released this year. Animals living in Latin America and the Caribbean took the biggest hit; their population sizes decreased by 94 percent. Habitat destruction is cited as the leading cause of these massive losses. The United Nations’ Global Biodiversity Outlook report produced similarly grim results. The document took inventory of 196 countries committed to recovering biodiversity as determined by the 2010 Aichi Biodiversity Targets. As dictated by the Aichi agreement’s ten-year plan, countries were to achieve certain recovery milestones like preventing the spread of invasive species and conserving protected areas. Most of the goals were not achieved or only partially met.
