Have you ever heard of the Antiquities Trade? That's the buying and selling of cultural art and artifacts. This is done every day legally by museums all over the world as they enrich their collections. But it is also done illegally and on a far greater scale by looters and thieves on the Black Market.

Artworks are often looted during wartime. Some important pieces are also damaged or lost forever as a result. During WWII, the Nazis took thousands of paintings and sculptures, and even though many have been recovered over the years, most are still on the long list of lost, stolen, or looted works of art.

Topic: Many museums today are faced with a dilemma about returning works that are discovered to be stolen. Should there be an immediate obligation to return culturally significant art treasures, even if it means returning them to where they were looted from in the first place? Who decides what can be returned and what can't? Can a museum keep another country's artifacts and cultural heritage just because the art could still be in danger?
