Do vegans realise that biodiesel is made from dead animals? Does that mean they can't take the bus?

I would think if someone is Vegan, they will have thought it through.

If it was to bother them, the plastic for their shoes/sandals will have come from the same source,

so they will be walking bare foot.

Actually they will be staying off roads because the surface will also have been made with oil which came from the same place as the Bio Diesel started off.

There was on this planet,

only earth/minerals, H20 and air/gasses and everything else that follows is vegetation or living beings, or the remains of those.

So is normal diesel, technically...
