透過介紹世界各地新奇有趣的綠化設計，帶領聽眾認識「城市森林」這個具前瞻性的城市規劃概念，提倡透過有規劃地於城市種樹造林和綠化，減低市區的熱島效應，為都市人締造一個優美舒適的居住環境。

By introducing new and interesting green designs around the world, the programme educates the audience about "City Forest". It is a forward-thinking concept of urban planning which advocates tree planting in urban areas to reduce the heat island effect, as well as create a pleasant and comfortable living environment for urban citizens.
