Weekly reflections venis, T1 W7

Kia Ora, this morning we had to write about one of the questions we had in our weekly quiz we had just before, the place im talking about is Venis, Venis was recently on the news for their canal going through there town ship/city. Their canal is much cleaner with the corona virus and Italy on locked town so there in no more tourists. My opinion is that that's really good that its cleaner but they should get a sewer system.  What do you think about this, and what do you think they could do to keep it clean?
