<Gacs Ivan>-nak. Mindebek elott soha nem talalkoztunk,tehat "szoba
allas" a kerdesen kivulli.                                          A
Donnela Medowes soraira adtal cafolo adatokat.Ami az lukakat tett
Dr.Medowes allitasaban. Orulok hogy legalabb buszke vagy a
szamitasaidert tett megjegyzeseimre.
A megjegyzesimet azon cikkben a Dr.Medowes allaspontjaira volt
hangsullyozva. Sertodesed tehat talan "magas polci" szolidaritas Dr.
Medowes-al.Nem????                                 Megjegyzeseid a CO es
CO2 kemiai modon valo alkalmazasi koltsegeire,csupan csak emlekztetni
tudom az olasot,hogy nem reg ,alig mas fel ev szazada (Col.Drake
sikereig) meg a ko-olaj lete sem volt ismeretes.
Remeltem volna hogy tobb hited es remenyeid lennek a tudomany es
technoligia teren,megoldasokat kidolgozni sok mai problemakra.Csak
nezzunk vissza,mennyi dolgokat ma veszunk minden-napiknak,amik csak par
ev elott ismeretlenek voltak.
<Liptak Bela> Al Gore sorai elkabitott Teged,mert egyett ertett a Duna
problamairol.  De hajlando lennel az o meglatasai szerint minden
belso-egesu-motort a foldon fel adni????    S amiket irtam tobbszor a
magyarorszagi folyok szabalyozasirol es az erdok teljes
eltunteteseirol,ketsegtelenul Te soha nem olvastad.
Mit ad az L.Pinter altal kozolt cikk e-rovaton???? Mi jelentesseket ad a
folyok szabajozasai altal eltuntett nedves teruletek es az erdok
pusztitasairol.?????? Nem azokat predikaltam mar regen????
Mi tortenik most a csatornava alakitott Tisza-tokkal a "re-charge"
teruletek nelkul???? Mi lett a fatlan orszag befolyasolasa a climan???
Mind azt csupan a szantokka valtani,mar mas-fel-evszazad ota.
Mi itt azokat hamarabb belattuk a Kissimmee folyo szabalyozasaval.De az

Kedves Laszlo. Orulok hosszu ertelmes soraidnak,s kulonosen a tobb napi
ures lpok utan.                                                  Eleg
eggyett-ertoen mutattal ara amiben velekedek.
Soha nem mondtam hogy nincsennek problemak,s teljes gozzel elore
pusztitani a termeszetet.Epp ellenkezoen.                    De a
valosag,hogy a politikai on-erdeku celokra tett tomeg kabitast adataik
alapjan vizsgaljuk meg.                                            Al
Gore problemaja  a politikai compaign-ben hogy nem kepes az igazat
mondani.Hat hogyan lehetne ecologiai elkepzeleseit biztosra venni.
Minden ismert letezo adat bizonyitja hogy a Fold klimai allapota allando
valtozasokban volt mindeg.Pl.megbizhato adatok alig mennek vissza a mult
szazadba,de ketsegtelen hogy a Foldon egy "kis-jeg-kor"uralt a
kozepkorban.Az volt a vilag lakossag szamanak lappangasi oka, a 15-16-ik
szazadig.                                          Ugy szinten,a
vulkanik eruptions esete.A kutatok letezo adatai szerint azok ma
novekedok. S ha az tett volna magas sulfa altali pusztitasokat a
termeszeten,hogyan volt  az egesz fold felszine suru tropusi
novenyzettel takarva? Meg a mai Siberia es a sarkokon is? Mi okozta az
azonnali valtozast? Mert a szoros mammoth szajaban a legelt novenyzet
meg ma is eleg friss hogy salatadban fogyaszthato lehetne. Azonnali mely
fagyas ahol tropusi klima es novenyzet letezett orakkal elobb?
Soha senki nem adott valszt, pl. hogy honnan jonne az extra viz,az
eszaki (iceberg)jeghegyek olvadasa eseten? A jeg-hegy elolvasztasa nem
adhat egy extra molekula vizet sem mint amit ma ki terit/kinyom a viz
alatti elfoglalt reszevel.    A vizszint folotti resz az expension a
fagyas altal.De az eredeti viz-osszege mint sulyban ugyan az. S a
hegyeken levo ho es jeg takaro alig tudna az aquafer szaraz szomjas
hianyait helyre allitani.       A tengerszint emelkedese a viz
homersekleti emelkedese okozza,amit a mid-oceanic vulcanic eruptions
okoz.     Adatok es professional gyakorlatom szerint a potable (ihato)
viz hianyossaga fogja korlatozni az emberi leny szambeli
novekedeseit.Ami problema vilagszerti.
Fa-iapar,fa termeles.Ne feljtsed,eszak amerika aldva van me ma is a
fa-termeles lehetosegevel,csupan Scandinavia es siberia kivetelevel. S
fa,ugy mint gabona ismet termelheto cikk. Persze termelesi ideje  nem 6
honap,hanem 20-30 ev.De ha nem aratod,elrodhad,mint a gabona ,tehat
ismet termelheto termek.
Teljes foku termeszet vedelem es helyre allitas az eredti

Itt  egy ujabb adalek a GMO  vitakhoz
_______________________________________
By Sam Venugopal


Genetically modified foods have transformed agriculture and have shown
great promise for improving human health.  Through genetic engineering,
foods can now be enriched with vitamins and nutrients (?functional foods?).
Gene splicing has also shown promise for transforming pharmaceutical
discovery and production through plants that cheaply produce
difficult-to-manufacture proteins, peptides, genes, and small molecules.
In this article, Sam Venugopal takes a critical look at opponents of
genetically modified foods and urges that more science?good science?be used
to evaluate the costs and benefits of pervasive genetic manipulation of our
food supply.


Genetically modified (GM) foods are expected to revolutionize agriculture
by reshaping how society defines farming.  Genetics will transform farmers
into scientists and terms such as genetic recombination, bacterial
resistance, and tissue culture will become a standard part of their
vocabulary.  The agrarian roots that profoundly influenced the U.S.
economy and its social mores will come to depend as much as on gene
splicing as on classical breeding programs.

With the change that accompanies a revolution comes controversy that, all
to frequently, fails to separate truth from hype and the realities from
lies.  The inevitable change becomes even more painful when one considers
the romanticism associated with farming over the last 200 years.

The American farmer has generally been open to technologic change.  Much of
this attitude of openness is attributed to farmers? understanding of the
increased need to strive for methods that improve crop yields and,
subsequently, optimize the economics of an enterprise facing increased
corporate competition and shrinking margins.

According to Doug Doughty, a GM seeds dealer, ?US farmers embrace
technology very quickly.  Farmers want the newest thing on the market, the
latest technology.? Data from the U.S.  Department of Agriculture show a
6-fold increase in the use of GM seeds among farmers over the last two
years, during which time farmers planted 50 million acres with GM seeds.

However, under the guise of public education, special interest groups have
exploited the public?s fear of biotechnology and thereby impeded society?s
ability to take advantage of available technology.  The main argument of
these groups hinges on just two studies that show that GM crops are
harmful.

Arpad Pusztai, scientist at the Rowett Research Instituted (Aberdeen,
Scotland) conducted one of the studies, which found that rats fed GM
potatoes showed stunted growth and an increased vulnerability to disease.
What activists don?t mention are experimental flaws built into Pusztai?s
experiment.  First, the rat?s diet consisted exclusively of the GM potatoes
for a period of 110 days.  According to Scientific American, for this diet
to convert over to humans, individuals would have to be fed nothing but
potatoes for 10 straight years.  Another factor conveniently omitted from
protestor?s interpretation of this study was that both the control group of
rats showed similar health problems after eating ?normal? potatoes.

In addition, John Losey?s experiments at Cornell University (Ithaca, NY)
have been used to promote the fight against GM products.  Losey showed that
Monarch larvae died when fed milkweed leaves laced with pollen obtained
from GM corn (Bt-modified).  As was the case with the potatoes, the amount
of Bt-pollen that was given to the butterflies in no way represented the
realities the insects would face outside the experimental setting.  Losey?s
data, coupled with America?s seemingly newfound interest in butterflies,
helped add to society?s misunderstanding of GM foods.

This is not to say that society should blindly accept all GM organisms in
every circumstance.  Scientists should strive to present the pros and cons
of the GM foods debate rationally and impartially.  Systems should be in
place to test and monitor the safety of GM foods, both pre- and
post-marketing.  In his book, The Coming Biotech Age, Richard Oliver
writes, ?The lack of understanding [regarding GM foods] should lead to
calls for more science, not less.  The emotional and irrational outbursts
of the anti-biotech lobby is fear-mongering of the worse kind.  It clouds
and distorts the debate, and seriously impedes the scientific discoveries
that could be the key to so many of the world?s most pressing problems:
global hunger, disease, and overpopulation.?

Indeed, even the strongest proponents stress the importance of not
proceeding without proper thought and reflection that must accompany any
new promising and powerful technology.  The Biotechnology Industry
Organization (BIO) ?Statement of Principles? even states in its preamble
the need to approach biotech with, ?an appropriate mixture of humility,
enthusiasm, and caution?biotech should not be viewed as a panacea or as
miraculous.?
