A simple question: When you buy something made of ivory, where does the money go? The answer may surprise you.

After guns, drugs, and humans, ivory smuggling is the world’s fourth-largest illicit trade. Poaching and illegal sales of ivory have grown so widespread — despite international condemnation — that we may see the end of elephants in the wild in our lifetimes. There’s really only one solution — end the demand. Stop buying ivory and spread the word about this trade, or say goodbye to elephants.
