Let's put it in perspective. Transportation makes up roughly 14 percent of the emissions. Let's use extremely conservative figures.

Let's take the most efficient mid-size car as an example and the heaviest breathing that you're likely to do. (get your mind out of the gutter Smiley )

Over 60,000 km, a Toyota Prius will emit 3.8 tonnes of CO2.
A person who cycles that distance (average fitness, average cycling speed) instead will produce about 0.38 tonnes of CO2.

Now while cycling, a person consumes oxygen at up to 10 times the rate of a person at rest.

Now the CO2 emissions per kilometer are negligible for a Toyota Prius compared to other forms of transport. We'll be really conservative and use a factor of 10.

Strenuous exercise is still 1/10 of that of driving the most fuel efficient mid-size car on the road. Normal breathing is about 1/100 of that emission rate.

So can you see that CO2 emitted from breathing doesn't really figure in the exercise? At the absolute maximum, it's 1/1000 of the transport sector or about 0.014% of total emissions, and that's being really conservative. It's probably 1/100 of that again.  It's negligible. I'll summarise with the following equation, where CO2(B) is the CO2 given out by the world's population while breathing:

CO2(B) = 4/5 x FA.    Grin

Good work Muso, very interesting pie charts and I especially liked your equation CO2(B) = 4/5 x FA.     Grin

But you didn't mention the 'regeneration' of the Oxygen by the now depleted forestations ...I reckon more than 60% reduction, just like a near 80% reduction in freshwater sources like Lake Chad, Baikal, etc - since 1900.
6 Billion people may be putting out smaller percentages of C02 in comparison to a toyota's emmission ...but I think the regenerative process has diminished considerably.

It didn't take much to make a giant Ozone hole (wonder how thats going these days?).

All out Thermocuclear Warfare/Holocaust was a REAL threat this this planet not so long ago and I tend to think Environmental Crises (be it warming or cooling or just flipping from one extreme to the other) is just as much as a REAL threat.

Yeah, that's usually factored into the Land Use and  biomass burning section, but you're quite right.

The last I checked, it's past its peak which was in 2006. Back to late 80's levels, but it will probably take up to 2050 to get back to normal, if it ever gets there.

The question is then -
how long have we got?

I would say about 1000 years left.


I don't think we'll die out, but the next 300 years or so will be a major test.  

I'd like to think that we'll start colonizing the galaxy.


I think we should be making a very large space telescope with a mirror
big enough to resolve planets.
See link:
http://rayvillard.com/articles/Beyond_hubble.pdf

If we could prove that earth like planets were around nearby stars then
an interstellar mission would find more encouragement.
The closest star is 4.2 light years away.
If we could make a spacecraft go 10% of the speed of light then a robot
mission would take 42 years to get there.
It could then transmit data back to earth which would take 4.2 years.
We could therefore have results in about 46 years.

Still - accelerating a space craft to 10% of C is beyond us right now.
It's a project that will happen when we get the technology one day  -
maybe in the next 100 years.



I'm not 100% sure that 1/10th of C is impossible......especially in a robot probe ship....it's just a matter of fuel load more than anything else...

In the overall scheme of things, both per capita & Total size are important.

Oh yes, we can see that if Australia cuts down it's emissions by half then that will save the world!

Why not fit a device to the arse of all our cloven hoofed beasts that converts methane into clean and pure oxygen. Why not get Australian of the Year recipient Tim Flannery to fit the devices with a little help from high priestess Penny Wong?

Why not just fit one TO Tim Flannery??
After all, he IS a horse's arse anyway..

You may find that Penny Wong would only fit the device to women, and then for fitting the device to men would exclusively be done by Bob Brown.

If the government was really serious about cutting emissions then they'd ban all Indian restaurants.
