Yup. See http://en.wikipedia.org/wiki/Food_vs_fuel
In that sense, we're lucky we've escaped the water-powered car (yet). It
always scared me to death to imagine that such a vital element for life
could be used as a fuel to propel cars, and be subject to all kinds of

Well, yeah, even without mentioning biofuels' efficiency and their
energy balance. There are numerous articles stating that it requires
more energy to produce biofuels than it produces.

Don't you get those?
They are mandatorily displayed under appliances on shelves, in France,
and people are paying more and more attention.

Worldwide production of vegetable oil and animal fat is not yet
sufficient to replace liquid fossil fuel use. Furthermore, some object
to the vast amount of farming and the resulting fertilization,
pesticide use, and land use conversion that would be needed to produce
the additional vegetable oil. The estimated transportation diesel fuel
and home heating oil used in the United States is about 160 million
tonnes (350 billion pounds) according to the Energy Information
Administration, US Department of Energy - . [...]
If the entire arable land area of the USA (470 million acres, or 1.9
million square kilometers) were devoted to biodiesel production from
soy, this would just about provide the 160 million tonnes required
(assuming an optimistic 98 gpa of biodiesel).

I do also believe that those prices rises are mainly due to speculation,
as oil price increases are, and that supply and demand regulations have
been long forgotten. But would anybody bother speculating to that scale
on the food markets if it wasn't for the biofuels, and the potential
benefits one can foresee in this fossil oil shortage context?
