Its cultural attraction can be attributed to its cultural diversity that reflects its colonial history and Chinese, Malay, Indian and Arab ethnicities. It is also environmentally friendly, and maintains natural and heritage conservation programs. As English is the dominant one of its four official languages, it is generally easier for tourists to understand when speaking to the local population of the country, for example, when shopping. Transport in Singapore exhaustively covers most, if not all public venues in Singapore, which increases convenience for tourists. This includes the well-known Mass Rapid Transit (MRT) system.
