and the moron in the white house goes to spend BILLIONS on going to MARS instead of backing his hollow words of LEAVE NO CHILD BEHIND!.AHAHAHAHHA
he's going to Mars and the children are going to the dogs

and making the WRONG choice once again! Don't worry W...it's only WHAT KEEPS THE PLANET ALIVE!!!!
Great Depths of Knowledge Await Below
The ocean floor is more promising than Mars rocks.

By Amitai Etzioni, Amitai Etzioni is most recently the author of "My
Brother's Keeper: A Memoir and a Message" (Rowman & Littlefield,
2003).

You can't accuse the Bush White House of excessive
imagination. The president's latest "vision" is a replay of
a 40-year-old idea stolen from JFK: men (and women)
heading for the moon and beyond by 2030. Real
creativity would set that crew down in another place
altogether: the deep ocean floor.

Although oceans cover more than 70% of the Earth,
less than 5% of them have been mapped with the same
degree of detail as Mars, and that was before the two
most recent Mars rovers, Spirit and Opportunity,
landed. We have rarely ventured below 6,500 meters in
the oceans, although they reach more than 11,000
meters deep. We know much less about the ocean
floor and the deepest layers of the oceans than we
know about either side of the moon. And yet, the
potential payoffs are huge.

Pundits gush over the fact that space exploration has led to its share of new
technology — for instance, NASA says the coatings that allow space capsules to
withstand the heat of reentry have been used in building better pots and pans, and
the miniaturization demanded by the small quarters on space vehicles has
advanced such fields as laparoscopic surgery. But deep-sea expeditions could
yield similar and perhaps even greater benefits. In order to freely explore the
oceans' deepest reaches, we must learn to construct submersibles that can handle
extreme pressure, as much as 18,000 pounds per square inch. The resulting
materials and techniques might help us design and construct homes that can
withstand being buried in debris after an earthquake or a mudslide.

I hope you are not one of those Americans who hears NASA talking about life
on Mars and imagines that we may find little green men who will ally themselves
with us against the Chinese. The reference is merely to cells of organic material
that may be present in the planet's dust and rock. In contrast, the deep oceans
are packed with complex, mysterious, intriguing creatures. In fact, it is estimated
that there might be up to 2 million marine life forms that are yet to be discovered.
Whenever we venture deeper, we find new species such as lithistids, a rare kind
of sponge present only in deep waters. Such discoveries are likely to reveal
secrets of life on Earth and even make up for other species that are being lost due
to human expansion on the surface.

Mars' organic limits mean that it is hardly a place to look for new medicines,
unless one wishes to carry red mud millions of miles back to Beverly Hills so that
we can all get Martian facials. But like jungles, deep-water habitats teem with life
and contain the promise of new drugs and new cures for diseases. In what are still
largely unexplored deep-water reef communities, the Harbor Branch
Oceanographic Institution in Ft. Pierce, Fla., has already discovered what is
believed to be an anti-tumor agent (discodermolide); its value for humans is being
tested now in clinical trials.

And there may be other answers under the sea to Earth's pressing problems.
Scientists believe that organisms in the deep oceans can consume the methane
that is seeping through the ocean floor and convert it into energy for themselves.
Some theorize that we could learn to harvest such energy for our own use.

And how do Martian finds compare? I don't know about you, but the discovery
that dust on Mars is finer than previously thought or that water once may have
flowed down its barren craters doesn't bowl me over. Even the seas' more
obvious secrets are much richer — for instance, sunken ships. Consider the
Swedish warship Vasa, which sank in 1628. Raised in the 1960s, it now tells us
things about where we came from, what life was like for our forebears and how
far we've come.

Perhaps most important, the oceans are not merely the major part of our
environment — they are integral to its systems. They greatly affect the climate and
the conditions that allow life as we know it to survive. And yet we have almost
turned some seas — the Mediterranean, for instance — into garbage dumps. We
need to study and measure the health of oceans because it is essential for our own
well-being.

Those who believe that we can draw inspiration only from walking on the moon
and not from diving into the oceans may be too young to remember the
admiration with which many millions followed the explorations of Jacques
Cousteau. All we need is a good race with other nations — measured by how
much ocean we cover and who can find more goodies faster — and ocean
exploration will be all the rage.

So let's get going — down, not up. If I had a car, its bumper sticker would read:
"Blue yonder? Blue under!"
