Vad ca greu intelegeti ca oamenii de rand nu prea au nimic de spus...Statul are cuvantul ... si fiecare stat tine cont doar de interesul oamenilor din acel stat si atat...!

Pentru acest interes "patriotic" sunt oricand in stare sa incalce interesele altui stat.

Din acest p de v e bine ca s-a creat UE si Romania face parte din aceasta uniune.

Cand va fi un singur guvern mondial probabil ca egoismul acesta nationalist va dispare ...asa ca nu mai criticati globalizarea ca are si efecte pozitive!

Despre petrol si agricultura :

http://www.harpers.org/archive/2004/02/0079915

Plato wrote of his country's farmlands:

What now remains of the formerly rich land is like the skeleton of a sick man. . . . Formerly, many of the mountains were arable. The plains that were full of rich soil are now marshes. Hills that were once covered with forests and produced abundant pasture now produce only food for bees. Once the land was enriched by yearly rains, which were not lost, as they are now, by flowing from the bare land into the sea. The soil was deep, it absorbed and kept the water in loamy soil, and the water that soaked into the hills fed springs and running streams everywhere. Now the abandoned shrines at spots where formerly there were springs attest that our description of the land is true.

Plato's lament is rooted in wheat agriculture, which depleted his country's soil and subsequently caused the series of declines that pushed centers of civilization to Rome, Turkey, and western Europe. By the fifth century, though, wheat's strategy of depleting and moving on ran up against the Atlantic Ocean. Fenced-in wheat agriculture is like rice agriculture. It balances its equations with famine. In the millennium between 500 and 1500, Britain suffered a major

Then the illusion slipped. On a whim I asked my hosts about another , older

oilfield called Ghawar. It is the largest field ever discovered, its deep

sandstone reservoir at one time had held perhaps one-seventh of the world's

known oil reserves, and its well produced roughly one of every 12 barrels of

crude consumed on earth. In the iconography of oil, Ghawar is the mythical

giant that makes most other fields look puny and mortal. . . .

"At Ghawar,' he said, 'they have to inject water into the field to force the

oil out,' by contrast, he continued, Shayba's oil contained only trace

amounts of water. At Ghawar, the engineer said, the 'water cut' was 30%."

"The hairs on the back of my neck stood up. Ghawar's water injections were

hardly news, but a 30% water cut, if true, was startling. Most new oilfields

produce almost pure oil or oil mixed with natural gas--with little water.

Over time, however, as the oil is drawn out, operators must replace it with

water to keep the oil flowing --until eventually what flows is almost pure

water and the field is no longer worth operating."

"Ghawar will not run dry overnight, but the beginning of the end of its oil

is in sight." Paul Roberts, "New Tyrants for Old as the Oil Starts to Run

Out, " Sunday Times (News Review), May 16, 2004, p. 8

Astea sunt din 2004.

Pe 11 septembrie OPEC se intalneste, sa vedem daca va creste productia. Nu cred insa ca vor spune " nu putem creste productia" - o asemenea stire ar afecta economia mondiala. Poate vor spune : "e destul petrol pe piata" sau "vom creste productia dar avem nevoie de investitii"

Aici sunt datele despre productia de petrol : http://www.eia.doe.gov/emeu/international/oilproduction.html

Maximul productiei de petrol a fost atins in iulie 2006, si eu cred ca nu au cum sa extraga mai mult. Daca productia va creste inseamna ca nu atunci a fost varful. Petrolul e un lucru finit :

New research by a University of California petroleum engineering professor suggests that worldwide crude oil supplies will start to run so low over the next nine years that resource-blessed countries like Saudi Arabia will begin to hoard them for domestic use instead of exporting -- and states with large reservoirs of natural gas, like Montana, will seek ways to avoid sharing with less-advantaged neighbors like Oregon.

Attempts to forestall the political and economic damage by turning aggressively to agriculture for "renewable" transportation fuel in the form of ethanol will prove futile, according to professor Tad W. Patzek, as new calculations show that the entire surface of the Earth cannot create enough additional biomass to replace more than 10% of current fossil fuel use.

Un raport de la Energy Watch Group in pdf:

http://www.energywatchgroup.org/fileadmin/...ort_10-2007.pdf

CONCLUSIONS

The major result from this analysis is that world oil production has peaked in 2006. Production will start to decline at a rate of several percent per year. By 2020, and even more by 2030, global oil supply will be dramatically lower. This will create a supply gap which can hardly be closed by growing contributions from other fossil, nuclear or alternative energy sources in this time frame.

The world is at the beginning of a structural change of its economic system. This change will be triggered by declining fossil fuel supplies and will influence almost all aspects of our daily life.

Deci ce crezi tu Harald e ca cineva ne pacaleste ca petrolul e pe terminate ca sa intelegem si sa nu protestam cand platim mai mult. Anume companiile petroliere si prietenii lor din politica aduc toate zvonurile astea cu Peak Oil ?

IEA - International Energy Agency minte ?

Nu exista tari in care productia a crescut, a atins un maxim si a scazut ? Romania de exemplu :in 1976 produceam 250000 barili/zi , azi 125000 barili pe zi. USA in 1970 vreo 20 milioane barili/zi, cel mai mult din lume, azi vreo 5 milioane

E ceva la fel de natural ca rasaritul soarelui. La fel cum se intampla in fiecare tara se intampla si pentru intreaga planeta. Daca in fiecare tara productia scade , poate totalul sa creasca ?

Acum suntem pe un platou, cand o incepe si Middle East sa scada o sa incepem sa coboram.

Daca spui ca toata treaba se face pentru profit asteapta sa vezi oamenii cum iau cu asalt benzinariile, cum se omoara pentru mancare si banii nu mai au nici o valoare, numai mancarea si armele. Ce profit o sa mai fie atunci ?

Indiferent de ce planuiesc aia de sus, e o realitate ca petrolul e un lucru finit, si e pe terminate, adica productia e in scadere.

1. Petrolul e un lucru finit, e singurul lucru cu care suntem de-acord. E o chestiune de bun-simţ.

2. Petrolul nu e "pe terminate".
