I think that conventional, store-bought fertilizers are regarded these days as a no-no. They're derived from fossil fuels in an energy-intensive process, and in the long term are bad for the soil. Composting all the way!
But you're right - burning soil does sound like too much trouble.
Also: I recently read a comic called "As the World Burns". I got it from my local library, and was surprised to find that it echoed many of the apocalyptic thoughts from this thread, and called for an armed uprising! One of the heroes of the story is a cute widdle bunny who bombs dams and burns down animal testing labs.
I'm a pacifist (or just a pussy, maybe) so can not really get down with the revolution, but the book was an eye-opener in many ways, and worth a look. Did you know that in urban areas golf courses use as much water as people do? Remarkable!
