What is the current wisdom about having an android device always plugged in? Some people say that it will kill and pillow the battery, but does it really?

It’s not only about the pollution: Cruise ships are also bad for cities as cities. A cruise ship will vomit 5000 people into your city center. Most european city centers are quite small, so 2-3 cruise ships will totally overcrowd the city. People might buy some tourist shit, but they will get their breakfast & dinner on the cruise ship. That’s bad for local restaurants. They will not stay overnight, which is bad for local businesses, hotels etc. And they will push out other tourist, because who wants to stay in Dubrovnik when the experience is like this?

It really does make sense for cities to ban cruise ships and advocate other types of tourism, where the tourists are “doing” more for the local economy.

This can start a death spiral - the more cities & ports are banning cruise ships in the Mediterranean, the more traffic the other cities will get. That will increase the problems there, leading to demands to also ban cruise ships there and so on.
