Cuba

While watching the national news on NBC tonight, I heard the following facts about Cuba that I thought was interesting:
7,000 Cubans fled to America this year saying that the considers in Cuba are unbearable.
This week: 40 people, including children, may have died on a smuggler’s boat that disappeared.
A group of Cubans made a home-made boat to try to reach the U.S. No one has heard from them so their families do not know if they made it or not.

Hopefully, we'll hear about these missing people soon, but I wonder how many people try to take refuge or immigrate to the another country that just go missing...
