It is so hot when walking under the sun in the afternoon. There are barely trees or other plants on the street to shade the pedestrians. Only few particular spots in town would find big trees like this, but normally these are some isolated places. Although trees always give way for urbanization but I am sure the architects and town planners will not prefer to walk under the direct skin-burning sunlight. If they can face the challenge to build a city which is balance between green & concrete, just to put a little more thought in building design & town planning, the environment we lived will certainly become better.
