War graves

[diverbrian]

Renewable resource sort of however the number of ships sinking is dramatically less than it was even 40 years ago with modern safety equipment and such.

2 world wars have contributed a lot of wrecks, we may not have another one (unless bush remains in charge!) and in general large scale naval conflicts are not a very common occurance these days.

Yes, we may be depositing some new wrecks all the time but the number will be lower than before.

Try far lower. In the Great Lakes, it is big news if something happens to a large ship. Up to about fifty years ago, it was far less common for a ship to go it's career without finding itself on the bottom of one of these lakes. With more rigid "Rules of the Road", modern radar, decent weather forecasting, GPS (helps on those shoal issues), and radio communications with other ships are more able to either stay out of bad weather conditions or navigate through them using "common sense" if they have to. No ship is unsinkable of course, but it doesn't happen near as often.
