Safe code can run in any situation where you can run C# code (Silverlight, shared hosting ASP.NET, XNA, SQL Server, etc.), while unsafe code require elevated trust. This means you can run your code in more places and with fewer restrictions.
Also, it’s safe, meaning you don’t have to worry about doing something wrong and crashing your process.
