here goes another wannabe scientist thinking he knows it all.
yes they do take it into account of course, you ain't the smartest you know, and CO2 capture from its biological mass has its limits, obviously.
and since obviously CO2 is still increasing, obviously plants are not enough ...
funny you pointing at the lack of education of scientists, you have high opinion of yourself, so why don't go write a paper and got yoursellf peer-laughed at?

clearly you seem to categorize yourself in the 5% retard every group contains?

like... her army ? http://en.wikipedia.org/wiki/Commander-in-Chief_of_the_Canadian_Forces
The Commander-in-Chief of the Canadian Forces is the supreme commander of Canada's armed forces. Constitutionally, command-in-chief is vested in the Canadian sovereign, presently Queen Elizabeth II.

I agree with you this situation would not happen, especially with King Harper's rule... yet... If she has NO power, WHY is she our Queen ? Why when do you become canadian, do you have to pledge ALLEGIANCE to the queen of England ?
Serfdom is serfdom, however non present or innocuous it seems.

How exactly could you revoke the Queen decision when her kingly hand has the power to veto any canadians laws that would be voted to that effect...
The PM and the representative are officially bringing suggestions to the Queen. Wether used or not, whether at the good will of the current king or not, power is power, nothing prevents from misuse... and that's precisely the danger of kingdoms...
I do agree canadians don't think that much of her, she has small impact, yet her power remains...
when doing defense contract in IT, every official document is written for one person, her majesty the Queen. and intellectual property belongs to her...

French Canada here... Ya the Queen is just a "title" whose picture is on every 20$ bill, on every stamp, and we have to pay millions for the living fees of the hard working royal family. Title yes but she is officially our master and her governor signs every law before being in effect... she has possibility to interfer, because she is officially the Queen of Canada, our Queen, period. She has power to refuse a PM, Every official paper or court order is in its name. Whether she looks like a inoffensive figure, she is still our master by law... and Canada belongs to Her.

to escape Earth dying athmosphere, enlist yourself for an endless life of slavery for the Mars Minig Corporation to pay for your oxygen and food.

So let's not risk anything on our territory. Our kind and over-nuclearised french neighboor will kindly produce for us. All safe now.

We have all elements deposit we might ever need for a long time on this very planet, we won't find new energy sources either (no biologic form to create rich deposits) and sending it back ressources would be costly. Trend is to develop industrial capabilities to use resource on site ( water, oxygen) to avoid the huge cost of lifting them. This is an human adventure and as long as we stick to one planet our survival is not assured with the usual statistically periodic & cataclysmic asteroid fallout or most probably die before of choking on our own air.. Mars is a dream of potentially being a whole constructive adventure, when we bring life and try to terraform a whole palnet with vegetation and I hope some day in future, will show greater value of "natural" ressources. gogogo!!!
