By Anjum Altaf The proposal to transform the greenbelt along the Lahore canal into an expressway in order to relieve the congestion of traffic has predictably divided citizens into two camps. The environmentalists bemoan the damage to nature while the developmentalists consider it the price for progress. Both sides rely on highly emotive sentiments and there seems no prospect of either convincing the other based on refutable evidence or logical argumentation. This outcome would be understandable in the Age of Faith but seems strikingly bizarre in the Age of Reason. In the previous post I proposed one way to resolve this dilemma. In this post, I use the work of Jane Jacobs, perhaps the wisest urban scholar of the twentieth century, to further advance an analytical approach to the issue.
