The concept of "City in the Garden" makes small islands with limited resources become the country with the highest green space per population in the world or 66 square meters per person. 

        A City in a Garden is a policy that Lee Kuan Yew has set as a goal. Gather multiple experts from architects, engineers, arborists to help design the city plan systematically for the most efficient use of space. Massive tree planting has become a national agenda. 

        This was followed by the issuance of a policy to preserve the trees and strict enforcement of laws. 

        Trees with a diameter of 30 centimeters or more are considered conservation trees, can't cut even if it is a tree planted in a private area. If necessary cut, must apply for permission and pass an arborist assessment first. 

        If necessary, cut down the tree. The cutter is always responsible for replanting and may need to be planted in a ratio greater than one to one.
