Cruise ships are getting bigger, and the smaller ships are looking for other ways into land via ports that haven't even been established yet. These smaller ships (3000+ people) are older and lack the cleaner set up of the newer ships. These ships are not well maintained and have a history of pollution and accidents. We do not need to cause further harm to our environment and the precious Chesapeake Bay. Please protect our air and our precious ecosystem from these monstrosities.  Putting bans on scrubbers would help protect our fragile ecosystem and forcing the ships to use shore power if they came into port would also help protect us from being overrun by these foreign flagged ships that evade U.S. taxes, labor laws, and exploit the poor cities that host them.
