Want to help plant 20M trees by 2020? Go to teamtrees.org #teamtrees
Huge thanks to all the SVfromrs who organized this. My apologies for the repost.
These videos are from 2012 so my interest in trees goes back a long ways. I think these videos discuss two of the most interesting and amazing facts about our leafy friends: they are made mostly of CO2 (which comes from us breathing out amongst other sources) and they can transport water up a tube higher than any we can currently manufacture. So trees are out to get you. But we do much worse to them so we owe it to them to plant some more. 20 mil is a good start.

wish I wouldve known about you doing this.... I'm a nursery specialist I was waiting for you to talk about air bubbles!!! Keep in mind, if you buy a live (fresh cut) xmas tree, and it prematurely dies, i would say it 99% has air in the zylem tubes.... and you will see it more during periods of drought :) that is why it is very important to get them in water asap. Are you from florida??? my favorite trees in the whole world are banyan trees!!! I live in Pa :)

Is it corporate homophobia that required all males after the year 1988 to wear shorts like those? If he were female would the shorts be the same? Is this kind of sexist polarization rational? Hip hop is a homophobic movement

How many trees would it take in an enclosed environment to keep a human alive? Assuming of course food/water are a non-issue.

That's a really STUPID idea. When a tree grows it absorbs the carbon from CO2 and releases the O2 from CO2, we all know this. The problem is that people do not follow the carbon cycle, they just stop there. When the tree eventually dies (as they all do) it falls over and rots. Both bacteria and other life forms like Termites, consume the dead tree and all the CO2 goes back into the atmosphere. The termites also produce Methane which is 25x more or a Green House Gas as the original CO2. The result...the trees do absolutely nothing to mitigate CO2...got it now, good. STOP Planting Trees, unless you want to make furniture. If you want to know the real solution, look here >> svfrom.info/history/video/oJtsn4bQntaFqJU

I am unsatisfied. So I know trees emit oxygen, so are they breaking the co2 bond, emitting the oxygen and using the carbon?

nope.. they take from u right.. but they also give you clean oxygen so... u are not getting smaller qz u give and trees are not getting taller qz they give..

It seems, since the tree gives off oxygen, we are “borrowed life.” Borrowing from trees then giving it back. No matter whether we are the tree or the animal, our most basic purpose is the physical growth of the earth. All the rest is fun and games! It’s ALL just blowing bubbles.

Why they did not choose a project to plant let say 20,000,000 veggies instead and feed the world with it? are they not somehow like trees where they also need co2 to grow? Furthermore the rate of cycle form one seeds to a full mature organism would be faster. Maybe it is just another extreme, but something in between such as a much deeper algorithm which would take into account more than just trees would be maybe somehow much better.

How large of a tree would you need to provide enough oxygen for a single person if they're in a closed system together? Edit: also, would the person put out enough co2 for the tree to survive, or would the growth of the tree consume the carbon and eventually suffocate it?

About 16 years ago I owned a tree service business. Used to see some strange things in trees. Was doing a full dismantle one day and when the top third of the spar went down, I was getting shot in the face with streams of water pumping out from the face of the cut. One of them shot a couple feet in the air. And it was a lot of water, each jet was maybe 1/8" in diameter, and there were several. I'll never forget being so amazed by the pressure it was under, blew my mind. Another 2ft diameter tree had formed a void in the center somehow; when my chainsaw cut into it, about 15 gallons of water came pouring out and drenched me.

So if you cut the top off the tree will that allow air (oxygen) in and thus boiling the water at the top of the tree ?

Oh come on people! The structure of the tree is made by breathing in CO2, reducing it to CH2O by photosynthesis and building carbon chains. This is high school biology.

I just thought, if trees become less due to deforestation, and we also produce more CO2, wouldnt the trees of a certain age also be bigger than trees of the same age 200 or 2000 years ago because they have much more "nutrition"? Is there any Data on this?

Interesting bit about the negative pressure, but deceptive bit at the end about becoming the tree. The tree is also emitting freed oxygen, which becomes you, no? Also, there's the unspoken idea that by planting trees we're somehow helping with global warming or something, but not unless the tree dies and gets absorbed without being harvested as peat taking a very long time to capture carbon?

It's sad how many people couldn't realize that most of it was carbon dioxide, considering that burning logs make coals and burn to form more carbon dioxide.
David Meyer

But you eat the apple or the almond and you become bigger and the tree becomes smaller so there is really a beautiful balance that can exist between us and them or on a more general scale between oxygen using animals and green plants. The key is the summary equation for photosynthesis which can go both ways. 6CO2 + 6H20 yields 6O2 + C6H12O6 In green plants the sun provides the energy to drive this equation and the plant produces oxygen and glucose. The glucose can be chained together to produce starches and cellulose. The cellulose forms the structure of the plant up to giant redwoods and we can eat the starch as in grains or potatoes. Then is our bodies we reverse the equation, we digest the starch into glucose, breath in oxygen and metabolize the glucose and oxygen into carbon dioxide and water and get back the energy from the sun that was captured in the chemical bonds of the glucose. So that equation is fundamental to much of life on earth and glucose is an incredibly versatile substance. In us it is used for transferring solar energy. In plants it is used for building blocks (they also use some of it for energy - think of maple syrup).

It makes a lot of sense if you think about it. Organic mass is made of carbon. trees take in carbon dioxide and release oxygen, with the carbon portion of the molecule being kept to increase biomass.

If this blows your mind, take a step back and think about how humans breathe, and where both weight gain, and weight loss, occur. There are some studies going on around the concept that the only way you lose weight is by breathing enough (and your body properly utilizing breathing) to exhale it into the air (E.g. you don't poop out what you're losing in weight). I would say this is not necessarily a "new" idea; but, one that hasn't actually had intense study done around it, and isn't necessarily how most people understand weight loss. It's a bit more complicated than the description above; but, there's a TED Talk somewhere where he explains in more scientific terms and experiments why this is.

You can lose weight from losing water too through sweating, urine and breathing out water vapor, it is not the "thirst water" but water in fat and muscles as well that is lost while going in starvation mode or other causes.

I cant believe the dumbest & dopiest answers come from people that should know much better.I once asked some Engineers what do you think the Earth's mass is doing.Getting less more or always the same? One said more because the Human population is increasing.One said less because we are burning fossil fuels and so one.No one got it right.I asked a Highly Smart guy that ran a Gold Mine why do cyclones rotate clock wish in the southern hemisphere & anti- clockwise in the northern hemisphere.Wrong.I worked out the correct answer in 4 hours at work.But I was just a slow Learner at school.My hearing memory was below average .Not good at school. All you need in the modern world is a good robotic memory & you can go to uni & have any job you want.
