Biofuels, pollute, petrol, oil, kerosene, alternative liquid fuels, aircraft
Unfortunate if it is true. I would like to find out more about this (i.e. I am not sure I can agree with the claim that some biofuels may pollute as much as petrol/oil/kerosene).
It is good news that they are looking at development of alternative liquid fuels for aircraft, because, of course, oil (kerosene fuel for aircraft) is not going to last forever.
