Magnificent grafic, is an excellent and elegant design. Have you tried to contact environmental organizations, or even National Geographic? I imagine they would be interested in print it as posters.
Saddly, rhinos are side victims of the political problems in Africa. With the chaos resulting from the guerrillas, there's no how to control illegal hunting or traffickers. Even worse, guerrillla members often kill elephants and rhinos either to trade in ivory, or even for pleasure. Sick motherfuckers. Dictators are also a problem because they allow hunting, or they hinder the work of conservationists. It's all political bullshit.
