Singapore is one of the most densely-populated states on earth. It's also growing. Through reclamation its landmass has grown by an estimated 24 percent since 1960, with 5 percent (37 square kilometers or 14 square miles) added in the past 15 years alone. This artificial growth is fueled by materials from its own hills, the sea bed and imports from other countries. Along with creating new areas for residence, the reclamation has allowed Singapore to create large public spaces and entertainment complexes, including the Gardens by the Bay, a lush parkland created under the remit to turn Singapore from a "Garden City" into "A City in a Garden."
