IRON MAN #25 
(May, 1970) "This Doomed Land--This Dying Sea!"

When Stark's Meridian Island Project (headed by a well-meaning but misguided manager) wreaks havoc with the local atmosphere, it's up to Iron Man and special foe-turned-friend Namor the Sub-Mariner to end the vile pollution. Lots of bad Marvel science is on hand to drive this heavy-handed, "relevant" eco-tale.

xkot's Recommendation: 1 1/2 repulsors!
