Diesel engines: some misconceptions remaining

It's not unusual to see a bunch of "unadvised" people taking some lies about diesels as a postulate. The problem is more about the currently-available diesel fuel, petroleum-based and sometimes with an enormous ash content that increases its particulate matter emissions visibly, and sulphur that leads to the acid rain. What some dumb asses forget is that diesels don't need expensive changes to run on an alternative fuel currently too neglected: biodiesel. Even the great Rudolf Diesel, PhD, predicted these engines could help a sustainable agricultural development in areas like Africa and wherever there is a rural settlement. After some failed attempts to use coal dust, due to safety issues, he had an idea: using peanut oil, and it worked. But petroleum-based fuels like kerosene and then a heavier oily one named "Diesel fuel" were also used, and since there was never too much intention to really develop the "under-development" world in a sustainable way, the petroleum-based fuel started to be the standard. But the Arab Oil embargo opened the world's eyes for a while, when the phenomenon we currently know as downsizing had its roots. Once again, biodiesel was neglected.
And currently a war in the Middle East. Some dictators are getting out of scene, but lefties are always intending to blame on the United States for all the evil in the world. But since American troops went to Afghanistan, for example, men can shave their beards and not be beheaded for this, women can use those islamic veils instead of the burqa, and there were not just "nice Arabian guys" who had their lives changed in the war.

So, how many nice guys would need to die or get mutilated just for some drops of gasoline?
