It seems that biodeisel was mentioned in the news a few times due to a promise John Kerry made to encourage the switchover to it. The story I heard made mention that biodeisel can be made from the recycled vegetable oil and animal fat from restaurants.
If it gets to the point where biodeisel becomes a mainstream reality but if there's no way to verify whether or not the biodeisel comes from an animal source or not, would you make the switch anyway?
It seems like this would be a more complicated case than at first glance; it appeases most of our other concerns about the environment (made from recycled materials, cleaner burning), the economy (made locally providing jobs sorely needed in the US), and global politics (reduced dependency on foreign oil, less need to control other countries to ensure free flow of oil), but would you spurn its use if it has the possibility of coming from animal fat?
