Person dons protective garb and gas mask to go outside

This is from the the late 1960's to early 1970's.  It may have been a TV special segment local to Chicago TV possibly shown on WGN-TV or WTTW.  I get the feeling it was locally produced although it might have been a student or activist film made to alert to the dangers of pollution and distributed nationally.

As I recall a primary theme was a person dressing in protective gear prior to going outside.  This included protective clothing, gloves, boots, and a gas mask.  Outdoors everything seemed rather dreary and devoid of other people and animals.  Mostly empty streets and empty playgrounds, and maybe some dead birds lying on the ground.  It's hard to remember why the person went outside.  Possibly to go to work, go shopping, or to just find food/water in a future dystopia.

This seems to be one of the earlier examples of pollution warning programs, maybe in response to the book "Silent Spring" or some other industrial activities of the time.  It certainly was very scary (to a small child) which is why I remember the main gist of the broadcast but I don't have many more specifics other than the primary visuals.
