Compared to previous years, sea glass is getting more challenging to find for various reasons. One positive reason is that there is less dumping of glass in the oceans. Note that less trash means less glass. Also, manufacturers replaced the glass with plastic, which cannot turn into sea glass. So, even with tons of trash in bodies of water, plastic still does not break down the same way. On top of these two, more people are now searching for sea glass along shores and banks. So, chances are, someone already got the sea glass pieces before you.
