Breathing air is being a consumer, now?
I guess the trees have finally gotten organized to charge us for our use of their waste products... do they threaten an embargo? They gonna keep it in if we don't pay up?
Anyway, our most important economic activity is not consuming goods. Consuming goods is just the way the economy of individuals is interconnected into an economy of nation.
Our most important economic activity (unless we're blue-blooded inheritor class leeches), is to do work. Work creates value, and value is what we exchange for money, which we then exchange for goods and services. No work, no consuming.
