Biodiesel made from dead animals

Every time biodiesel is mentioned, everyone thinks of vegetable as its source. For this reason, environmental activist George Monbiot argued against it, stating the farming of crops such as palm trees would be worse than using fossil fuel in damaging the ecosphere.

But what would he say about running a car on a cow?

A Canadian company near Montreal has produced biodiesel from the remains of farms animals such as cows, pigs, and chickens. Remains include bones and inedible entrails.

We can't wait to read Mr.Mobiot's response on recycling gizzards. Personally, we don't want to be downwind of such a car.
