Within the 1920s, pregnant women were motivated to
drink Guinness to increase their own iron intake.
For decades i was all told to avoid greasy butter and
eat artificial margarine. Both pieces of wellness advice have since already been
discredited.
We are now studying that millions of motorists that
have bought diesel cars thinking they were less harmful to the surroundings have
been equally misguided.
Diesel powered cars emit less co2 (CO2) than their
petroleum equivalent, we were told. Actually not only are CO2 emissions almost
identical on average, but in reality produce large quantities of other
contaminants linked with thousands of premature fatalities.
Carmakers say they have already used action to reduce
emissions significantly, while regulators are beginning in order to acknowledge
the problem, but the problem remains enormous.
The reason is easy: about half of all cars presently
sold in Europe are diesel powered powered.
As Greg Archer at Brussels-based think-tank
Transportation & Environment says: "The car industry is battling to keep
selling diesel since it has invested so greatly in the wrong technology".
