Singapore- city state

It is one of Asia's busiest and most modern cities, yet it is also one of the Cleanest Cities in the World. The government has strong legislation in place to help support and keep the city immaculate in order to preserve its high status as a top tier city. Without permission from the authorities, you cannot uproot or cut down a tree. If you are detected littering, you will also be arrested.

It turns out that maintaining a city clean is a collaborative effort between residents and government officials. The eleven cities represented here have collaborated to provide a clean and safe environment for all. Any of these cities would be ideal for you if you were looking for a clean city to visit on your next vacation or if you wanted to relocate.
