Walls built around cities in good old times were for defensive purposes to protect citizens from enemies. With increased sophistication of destructive weapons at man's disposal, such wall are obsolete in our times. However, the solid waste wall being proposed is being mooted as a simple way of isolating the huge amounts of solid waste that is being generated in the cities. Such walls would ensure that cities do not destroy the environment with careless methods of disposing their wastes.
Folks this is the final page of Troff , but I hope it will be the beginning of a new chapter for many cities which seek to implement its concepts. It is my desire to jog on as many solid waste walls as may be be built in various cities of this world before my final comes!
