I assume the author meant that the tree stores about 48 pounds of carbon. Two mature trees can provide enough oxygen for a family of four." - Environment Canada, Canada's national environmental agency Ah well. "On average, one tree produces nearly 260 pounds of oxygen each year. doesn't add up to me? (And I definitely lost myself, doing all those conversions) = Ok, found the other statement too. Or, a pound and a half to just under two pounds/day." is one answer So assuming that the first statement is correct, and one tree is able to sustain oxygen for two persons, per year, then assuming that those use between 1000 to 1200 liters oxygen per day, then one mature tree should produce the same amount, possibly? And I'm getting a headache Arrggh.

That may sound like a lot, but there are only 1.42 grams of oxygen/liter at 0C, 1ATM. "Somewhere between 500-600 liters of oxygen (at 1 atm pressure) a day. Take a look here Ok, but how much would a average human consume per day then? That one seems possible to answer. So, how much oxygen is produced by one tree, per day? I don't know really? It's a complicated question it seems. (all depending on if I'm doing the conversions correctly here:). But the first number seems plausible, the second? 82600 liter per tree, per year, right? Divide with 365 and we get. To get to the carbon content you multiply that dry weight (in kg:s, please) by 50% and there kg seems a good choice too.

And then there is the question of what a weight means here, the dry weight of a tree is what's used in the pdf and that is apparently about 72.5 times its weigh, growing in its natural 'wet' state.

Then we have using kg:s O2, instead of using liters? One kg oxygen is about 700 liter so converting it to liter that will make 118 x 700 = 82600 liter oxygen if I got it right. Arguments for Land Conservation: Documentation and Information Sources for Land Resources Protection, Trust for Public Land, Sacramento, CA, December, 1993 How correct that is? Depends on what tree, I would guess? and the soil, and the weather locally. So what he suggest is that "1 mature tree can store 21,772416 kg CO2 per year and give 118 kg O2 per tree per year," right? The first number seems to come from "A single mature tree can absorb carbon dioxide at a rate of 48 lbs./year and release enough oxygen back into the atmosphere to support 2 human beings." - McAliney, Mike. I now looked at lbs and found it to be a pound? 0.453592 kg. But the pdf gives a estimate in the same eh, indecipherable terminology. I'll blame it on me being to lazy to convert it into meaningful numbers, as kg, for me. You're perfectly correct, I definitely missed to check his numbers and taken together they make no sense to me either. So, the CO 2 absorbed is about 3 times the value calculated above, or somewhere around 100 gigatons on the continents (with the caveat that most is released again, as mentioned). So, I presume you are saying that they are storing 2400 – 3600 lbs of CARBON per acre, not CO 2. The trees generally store hydrocarbons (chains in the form of CH 3(CH 2) nCOOH, and various other similar compounds, but mostly carbon and hydrogen). Are your numbers off a bit? The plants and trees absorb Carbon Dioxide (CO 2) + Water (H 2O). So, while about 36 gigatons of CO 2 is absorbed every year, the vast majority is released again by the plants in a cycle. Even the trees eventually die, and are decomposed. However, All plants are balanced with decomposers.

However, if you say 1 ton of CO 2 per year per acre, then one comes up with 36 gigatons of CO 2 being absorbed on the continents, plus what is absorbed in the oceans. That gives about: 36,677,592,320 acres, including forests, farmland, deserts, and glaciers. There are about 57,308,738 square miles on the continents on Earth. It is not quite clear what you are asking.
