Thanks Greg, I actually found that topic after I had posted mine. I am not talking about all the trash thats in the water but more like artifacts or fossils.Here is South Carolina you can get a hobby diver licence to be able to collect artifacts and fossils from state waters. The state requires you to report any find, the state will then release title to all find to the licensee.
Which brings me to another point about the trash. When diving do you try and bring something up to clean the water for the next diver. Yes we have lots of interesting items that can be found. If everyone brings up a small piece of trash it will definitely help.
