Joke of the Week:
What is (H2O)4?
Now the serious stuff:
This is no joke but a call to *BAN* dihydrogen monoxide, otherwise know as the invisible, killer
substance. Dihydrogen monoxide (DHMO) is colorless, odorless, tasteless, and kills thousands of
people every year. Most of these deaths are caused by accidental inhalation of DHMO in its liquid
form, but the dangers of dihydrogen monoxide do not end there. Prolonged exposure to its solid
form causes tissue damage and contact with its gaseous form causes burns. DHMO use is
widespread. For those who have become dependent on it, DHMO withdrawal means death. DHMO
can be an environmental hazard: it is a major component of acid rain, contributes to the
"greenhouse effect", leads to the erosion of natural landscapes and hastens the corrosion of most
metals. Being so prevalent (quantities are found in every stream, lake and reservoir), DHMO
contamination is at epidemic proportions. Despite the dangers, DHMO is often used as an
industrial solvent, as a fire retardant, in nuclear power plants and (can you believe this) in certain
food products. Companies dump waste dihydrogen monoxide into rivers and the ocean, and nothing
can be done to stop them because this practice is still legal. STOP THE HORROR NOW! The
American government and the United Nations have refused to ban the production, distribution or
use of this chemical due to its "economic importance." The navy and certain other military
organizations are highly dependent on DHMO for various purposes. Military facilities receive tons
of it through a sophisticated underground distribution network. It is also stored in large quantities
for military emergencies. BUT IT'S NOT TOO LATE! You can help. Act *NOW* to prevent
further contamination. Write your representatives. Start and sign petitions. Send e-mails.
Inform your friends about the dangers. What you don't know *CAN* hurt you and every individual
throughout the world.
