Drowned do not drop copper

I do not have access to the Bedrock Edition of the game, however, I can confirm that drowned zombies do not drop copper in the Java Edition version of Minecraft.

yes, they do not drop cooper in java.

does this mean copper will be renewable?

Yes it does, but keep in mind that the bug tracker is not for discussions. If you want to discuss something, feel free to that on the mojira discord server.

There are a lot of suggestions against Drowned dropping Copper over on the Minecraft Feedback site, and there are some with the idea of renewable Copper. You can vote and join the discussion there as well.
