Bangalore, the city of gardens is slowly losing it's sheen. Namma metro rail project, is causing lot of disturbance to the environment. Due to the construction, which is mainly through the arterial roads of Banglaore the level of dust pollution has increased. Owing to the construction trees are been cut down. Even trees in Cubbon Park are be felled. In present scenario of Global climate change, this can be avoided. Otherwise, trees should be planted at a ratio of atleast 1:10 trees that are felled. Hope, Bangalore will return to the time of tree lined avenues and the sulubrious climate.
