Sea Change

The UK invests 45m pounds for Sea Change for three years.
I think how to keep the cities clean is also very imoprtant as well as their design.
If sea side cities become beautiful, many people come and they flourish, but at the same time visitors bring a lot of rubbish. It can make them dirty easily...
