Yesterday I traveled From Faridabad to Delhi Domestic Airport via Karan Singh Shooting range road , Greater Kailash and found that foot path is being constructed on both side of road near shooting range and open space around tree is left, which is a good construction practice. In Greater Kailash and Airport area it is very hard to see trees, you are surrounded by all the concrete jungle. Instead of cutting the trees it is better to relocate the big trees if possible.
I think in view of Commonwealth Games some greenery must be maintained near airport area as it will not only help in maintaining environment and reduce pollution but also increase beauty of area.
