At present, now we live in the 21st centuries, the weather changes tremendously, the temperature keep on rising everyday. We able to feel the extra heat from our surrounding compared to last 30 years back.
During the 70th, there were more trees, these trees not like what we see now in the city so small and short. Big tall trees growth along the side of the road, very shady, can feel the fresh air. Even it was in the afternoon the heat was mild not like now, the heat can burnt skin.
Trees are very important, it serve many purposes, provide shade, convert CO2 to more O2. A place without trees have more CO2 which can contribute global warming.
