To help prevent or reduce the speed of global warming, adding a green open space with a garden on the roof of houses, buildings, hotels and offices is one effective way. Although the condition of the urban region largely filled by a high rise building, the designers (architects, and landscape architect) must create a green open space to add plants that have been taken over when the building was constructed.
By creating a garden on the roof, high-rise buildings can still have a green open space, because there is space efficiency. Park on the roof (roof garden) is as an alternative reforestation to improve the quality of big city environmental health.
