Oil: too valuable to burn.
Some would argue that now is the time to make best use of petroleum based or petroleum reliant products for things such as super-insulation for retro-fits (in new construction thicker walls are an option not requiring the high R" of foam), or for infrastructure projects such as irrigation piping, PV panels, et al. Whenever remotely possible: local, renewable/regenerative, low-impact, and low toxicity should still always be the preferred technique. After all, there's only a limited supply. Just a thought.

Point taken.  I admittedly was thinking of products like Icynene vs. straw, but it seems fossil fuels really are part of our entire world.

I'm afraid that fossil fuels are used for the production of most straw and since some of it is coming from Canada, there's also transportation costs. "Natural" building materials are not necessarily immune from the environmental costs of other materials.
