Why is Sentosa Beach in Singapore man-made?

Does the questioner want to ask "Why is Sentosa Beach in Singapore artificial?"

1. Geographic conditions: Singapore is located in tropical Asia and lacks natural beach resources. Because Singapore's geographical environment is mainly land and islands, the coastal areas are mainly sand and gravel, lacking naturally formed beaches.

2. Island planning: Sentosa is a specially planned and developed tourist attraction in Singapore. In order to provide tourism and entertainment facilities, including luxury hotels, resorts and beach experiences, the Singapore government decided to build an artificial beach in the Sentosa area.
