You forgot about the looming ice age in the 1970s, you also failed to mention our dying oceans (by mid 90’s due to acid rain), ditto our forests, lakes and streams...
The oceans are dead - fish are dead and the algae that gives oxygen to the waters are dying. Thanks, I forgot that liberal horror...
And acid rain also killed off trees and most of the crops... the horror... the horror...
Oh wait....
