Nowadays, major environmental issues are the object of large public
debates de- spite the fact that scientific knowledge is often
insufficient to draw unequivocal conclusions. Such is the case in
the ongoing debate regarding the specific contri- butions of
anthropogenic greenhouse gas emissions and of natural climate
changes to global warming. At least 10 to 20 years of additional
observations will be re- quired, before we will be able to
conclude, with certainty, on this subject. In the mean time, and as
directed by their immediate interests, people will continue to
promote contradictory opinions. The media are, in part, responsible
for perpetuat- ing such debates in that they convey
indiscriminately the opinion of highly credi- ble scientists as
that of dogmatic researchers, the latter, unfortunately too often
expressing working hypotheses as established facts. Naturally, in a
similarly mis- informed manner, pressure groups tend to support the
researcher whose opinions most closely represent either their
particular ideological battles or their economic interests and,
hence, in their own way, add further to the confusion and obscurity
of the debate. Only a few years ago, mercury (Hg)contamination in
hydroelectric reservoirs was the object of such media and social
biases. At the time, analytical data used to support the discourse
were themselves uncertain and numerous hypotheses, often times
fanciful, were proposed and hastily "delivered" to the public.
