Awwwwee you are very thoughtful! Yes. Too many careless tourists is harmful. Whichever beach I go, I always cut my swimming time if I see plastics or trash floating. I pick them and throw it at the nearest garbage can. But I can only do so little if I'm alone.

Same thing when we hike. We bring bags to put garbage we saw along the way and dispose of them later on.
