I got this idea from a server plugin
what if there was a small chance that every time you destroy a dirt, sand, or gravel block above layer 42 you have a small chance of receiving a
-opened tin can
-an empty cell
-uninsulated copper or tin wiring
-Weed-EX. (maybe, really small chance)
-RE battery(not charged)
basically stuff that you'd expect people had discarded into the environment.
obviously you wont be getting these every 5 dirt, sand, or gravel blocks. maybe <5% chance
maybe the chance of getting a drop doubles in beach biomes?
or have the world gen a generate trash blocks that are disguised as a
dirt blocks and drops either normal dirt or trash when broken (also have
this happen for dirt at any height think of using it in superflat)
