Why Trees Are Out to Get You

Want to help plant 20M trees by 2020? Go to teamtrees.org #teamtrees
Huge thanks to all the ALthers 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.

    I was reading "the secret life of trees" and there is a whole chapter basically saying science doesn't yet know how trees channel water to the top, and I remembered that I had watched this video almost a decade ago. Veritasium is cutting edge scientific knowledge, explained in ways the masses can understand. Superb.

    I don't get it. The soil in the pot decreased by 60kg and the tree was 72kg..... so wouldn't that mean most of the mass DID come from the soil and like 20-ish % came from the air? Or maybe the tree somehow uses elements in the soil but looses them (like leaves falling off the tree, etc?)

    Why did you repeat the first video in this one? And if you recruited Hank and these other people to talk to, why did you end up just talking to your own video clone? (I wish it could do that in real time. I can never find anyone as good to talk to as myself, for someone to nobody else seems to know anything, which is strange, because they went to school, but it really didn't. So like trees, I really don't know where the stuff I'm made of really came from. Could it be CO²? Some people think I'm kind of a wind bag anyway.

    it almost true. the tree consist from celulosa: C6 H10 O5. So need CO2 - x6 and H2O x5. this is not 95% CO2... And I think about this if I look in table Mendeleyev, and calculate molecular mass, and find if we Weigh the dried wood and mult on 1.3 coeficient we have all oxigen mass producted this tree throw all life... And this is not all... The tree is not help in correction weather... The solution in ocean, in in artificial shallow water... It will better And yes this will drive out plankton and whales - but we no longer have a choice. Unfortunately, today's scientists are impostors. I hope humanity will be able to return the level of moral values without war and resolve this issue correctly and humanely ... people in science are not scientists, but simply bearers of these titles to a greater extent ... And this is one of the reasons why no one listens to them ... Ilona Mask is a real specialist and he hardly speaks nonsense. And that why people listens him, but he see this problem, and that why he wants fly avay on Mars. ) unfortunately - war, and only war, reminds people about morality... And he understand this too, so wants take best of the best -- for try create best world. And this good dream too... it's like the story with the Lomehuza and the anthill, the anthill can be saved if you take healthy ants and put them in a new place ... But personally, I believe and know that everything will be okay with the world and with people for some time, too, and with the climate too, people will reach everything, but sooner or later people are fucked up on Earth and on Mars @ George Carlin - he is also right in this regard)) Then when the artificial intelligence learns to create flora and fauna ideally adapted to the habitat in any planet in any biologic base... People will see this wonderful world, plunge into a much greater depression and give way ...

    You want some ideas for shows or you still have thousands? Check this out since you're talking about trees. On a absolutely quiet night with no breeze or wind or loud sounds are happening take a look at a tree with leaves. From a distance the tree is absolutely still. Now move closer. Now really close. Now REALLY close. You'll find every leaf is moving. That tree is busy! All of it! Id love to see you try it. I really love your shows!

    ok so I get the whole team trees thing, but unfortunately the study which everyone is citing to say that trees are some of the most efficient producers of oxygen is completely false. Low to the ground plants like grass and moss are many times more efficient. In conclusion, what we should be doing is having 1 dollar = 1 square meter of moss. Bazinga

You are a young adult and you eat, get water, sun and excercise and... You grow two more legs under your feet so you get taller. You grow two more arms so you can reach and grab further. You get my point? How do trees do thaat?

    So are we saying that we can grow trees faster it we plant them in a carbondioxide enriched environment? Say for example a warehouse with the right light spectrum, nutrient enriched water and the ware house allows for the oxygen to escape but allows for more carbondioxide to stay in the warehouse?

    Forests stabilize micro and macro climates by: • Photosynthesizing sunlight through green leaves • Absorbing carbon dioxide from the air • Accumulating carbon in standing biomass - roots, stems, branches, and leaves - growing tall canopies for more efficient photosynthesis • Providing energy for respiration, pumping out heat waste and disorder • Evaporating water through leaves, dissipating heat to improve photosynthetic efficiency and cool forest areas • Recycling water vapour across valleys and mountains, increasing precipitation in marginal areas • Minimizing soil erosion with layers of leaf litter and growing interlocking root systems that help stabilize seasonally unstable hills and mountains • Adding nutrient-rich fallen leaves to the soil which becomes humus enabling forest soils to store more water and carbon than most other soils • Increasing the capacity of a site to support life, building on itself, stabilizing the site and the biota. Mineral nutrients are conserved and re-circulated, offering opportunities for more life • Building climax communities that are stable, self-regulating, self-healing, and resilient • Assisting in the essential global recycling of water, oxygen, carbon, and nitrogen - without expending fossil fuels. • Influencing the wind, temperature, humidity, precipitation, soil, and water and energy flow in ways often discovered only after the forests are cut, and these functions are reduced or lost • Maintaining high efficiency, low entropy processes: matter and energy are moved around as little as possible to minimize entropy (waste and disorder), information is moved around as much as possible to maximize synergy (efficiency and cooperation), to reduce entropy (waste and discord) • Providing energy for biosphere system maintenance and stability.

    @Christof Bodendorf I understand that Energy and Mass are the same. Energy mass equivalence. I was just answering the question and energy-mass equivalence didn't seem to be relevant. This spacetime vortex idea seems interesting. But is dismissible for now. Quantum field theory and Quantum mechanics do better on a scientific basis, at describing particles. I just really wanted to specify, when answering, That matter is not energy. Or at the least, science indicates that matter is not energy. Of course, no one definitively knows what matter is beyond the scope of QFT or QM. So I chose to answer by saying that matter is a temporary state of the quantum fields. When he said the energy was not matter. He literally meant that the energy was not from matter. But from the Change* in chemical energy (eV/c² mass) of CO2 and also from the nuclear binding energy (MeV/c² mass) of the nuclei. And I guess from the net momentum and intrinsic mass of the individual electrons. But what is important to note, is the Change! Of these factors. All of these factors contribute to the mass of CO2. CO2 formation releases a lot of energy, as CO2 is thermodynamically favourable. CO2 with other reactants then receive light energy and go through a complex chemical procedure, to form glucose. Glucose is high energy because it stores energy in its covalent bonds which have many possibilities of forming different bonds. Glucose polymers like cellulose, like lignin, hold high energies because of these covalent bonds. And of course. Energy is mass.

    @Degenerate Deuterium Well, I guess you are talking about a qumantim-electromecanical point of view. From the view point of the general relativity, some people think of an elementary particle as vortex of the Spacetime. Actually it is a quite intuitive imagination and I like it, but it is not a finished physical theory. However, my point is that Energy and Mass are *one and the same* property of matter. They are simply linked by the universal constant c^2. We could remove one of them from physics and theoretical physicists sometimes do this by setting c=1. Now, coming back to the topic of the video: Where does the mass of trees come from? In the Vertasium video we learn, it is basically the CO2 from air. And I agree that this is the mayor part. But the tree contains energy. You can burn it. And this is energy from the sun and it is certainly associated with mass. So a (probably quite small) part of the mass-increase of the tree origins from sun energy. The same is true for all fossil energy like petroleum. This is - from a physical point of view - a fundamental contribution. That's why I wanted to point it out, especially because the video denies it. However, it is probably a quite small part. But: some sun energy ends up on the earth - and increases its mass :-). (I am aware that there are other effects which are larger.)

    Energy and Mass are a property of their matter. None of those two former are matter. Matter is just multiple perturbations (particles) in a range of quantum fields, that bond together for metastability, that eventually decay (On the scale of trillions of centuries to dozens of miliseconds, it really depends). Matter is just a temporary symptom of the universes quantum fields seeking stability. Energy and mass are examples of fundamental properties of matter.

    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.

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.
