. . . The sudden public awareness of air pollution as 
environmental change is matched by the public 
awareness of “space pollution” by the manmade 
environments of roads and motor services. These 
environments had been relatively unnoticed until the 
arrival of the new electric information environment 
that eliminates all partitions and divisions. A new 
environment of services renders the old one visible 
for the first time, as it were.
