How many people cruise per year?

Millions of people cruise each year, but with the recent cruise liner accidents interest in cruises have gone down a bit, especially with the Carnival company. Cruising is a safe thing most of the time, but just like on land, something could go wrong, and people need to understand that. I think that people shouldn't stop going on cruises because a problem like the ones that Carnival ships have had don't happen very often. Cruising is safer than crossing the street most of the time.
