lots and lots of green cover of Lahore was lost with expansion of roads and the last govt. preference of decoration, decorative shrubs and flower beds instead of local big, shady and verdant trees...trees are needed and not decorative stuff.
This is a vicious cycle, expansion of roads>more cars>traffic gridlock>further expansion and less tree cover.
Ideally a robust public transport system with buses, a large number of them and not BRTS will help a lot, coupled with cycle tracks all over the city and walk ways and better footpaths.
Buses in all roads is the solution and not one or two corridor of BRTS.
