You are joking right?  Please tell me that you are not that confused about the role of FF's as the backbone of the modern lives we live?  Because no one is using Bitumen to heat their homes.  It isn't sludge, it is a High value product that is used to make:  Gasoline, Diesel, Jet Fuel, Petrochemicals,.  All of which, unless of course you live in a cave, you use daily in one form or another.  
Eat food?  You use FF's.  Use a computer?  You use FF's.  Heat your home?  You Use FF's.  Drive a car?  Fly to any destination? Have a Gore Tex rain jacket?  Take the bus?  I think you get my drift...
