Water hyacinths wreath a hippopotamus in Mana Pools National Park, Zimbabwe. Across Africa, hippos are targeted for their ivory teeth, and populations are in decline. This November, the 19th meeting of the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) convenes in Panama. Nations of the world will weigh proposals to strengthen (or weaken) protections for species adversely affected by international trade. One positive proposal would ban international commercial trade in hippos and hippo parts.
