Hi @kikenexum, yes, I can imagine that under water we can see everything that human just thrown into water so that we can not see, but those garbage not disappeared but are there on the bed of seas and oceans, many sea inhabitants getting trapped or swallowing all those stuff and can die. Seas need to be protected equally like any other natural spaces. I think it is very good idea to have a net with you and collect some garbage when you are diving. I hope it did not spoil your mood of diving. Thank you for stopping by :)
