Back in 1969, air-pollution researcher Alfred Hulstrunk had arrived at the pessimistic conclusion that pollution levels were getting so bad that within 10 to 15 years every man, woman, and child would need to wear a breathing helmet to survive outdoors. And within 20 years, he predicted, everyone would have to live in domed cities.
Part of the problem, Hulstrunk believed, was all the stuff that society produced, such as "plastic beer containers that can be burned instead of just discarded." When burned, the beer cans added to air pollution. He noted, "Aesthetically you improve your area so that you don't have beer cans along the road, but now you are breathing beer cans."
Therefore, Hulstrunk had prepared for the future by designing an air pollution survival suit "to prevent inhaling beer cans or any other matter."

It looks like Hulstrunk is still around, now aged 90. He recently gave a talk at Cedars of Lebanon State Park
