Of course roads are needed. But there are at least two problems with such a deceptively simple statement: 1) Road construction is constantly expanding. They create their own demand by diverting resources away from many things including affordable housing -- the number of people I know that commute for over an hour because they cannot afford to live near their work is non-negligible. At some point this becomes a planning/resource issue and at the moment the decision is to carry on as usual with a system that is causing major problems. 2) The amount of traffic makes a huge difference. It is well documented that roads create ecological bubbles affecting animal populations negatively. The speed and frequencey of the traffic (type of vehicle) makes a difference.
