    TUHOKlimaticka zmena / Thank you so much for ruining my day


    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."


    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?
    Ale take jak funguji masove dezinformacni kampane ropneho prumyslu a boj o verejne mineni na prahu noveho klimatickeho rezimu post-holocenu.

    LINKOS: najdes mi srovnani, kolik da krava krmena sojou? :]

    'ta sója z jižní Ameriky jaksi není určena pro lidskou populaci, ale právě pro ty krávy ve velkochovech'
    z udaju co jsme nasli to vypada, ze z pulky je urcena pro lidskou populaci, z casti pro technologicky procesy a jakozto krmivo je naprosto marginalne pro skot. nebo mas jine udaje?

    LINKOS: jde o slozeni potravy. do krmny smesi nebo k pastve jim muzes pridat trochu nejakejch obilnin [spatny pro populace bachoru, spatny pro klima], soji, kukurice, atp. ale hlavni je objemova slozka, tzn. to 'malo vyzivny' co spasou, nebo jim je dovezeno - slama, travy, atp. nebo nejaky jejich formy.

    pro koho pestujeme ta krmiva?

    Study predicts the oceans will start emitting ozone-depleting CFCs
    https://phys.org/news/2021-03-oceans-emitting-ozone-depleting-cfcs.html

    By the time you get to the first half of the 22nd century, you'll have enough of a flux coming out of the ocean that it might look like someone is cheating on the Montreal Protocol, but instead, it could just be what's coming out of the ocean," says study co-author Susan Solomon, the Lee and Geraldine Martin Professor of Environmental Studies in MIT's Department of Earth, Atmospheric and Planetary Sciences. "It's an interesting prediction and hopefully will help future researchers avoid getting confused about what's going on."

    tak na ty produkci ty taxiformis rasy pracujou dva startupy, symbrosia na hawaii a volta ve svedsku, ty to maj asi rozjetejsi



    A startup out of KTH Royal Institute of Technology; Volta Greentech and Symbrosia from Yale University, are both working to grow A. taxiformis. Symbrosia is looking to integrate the cultivation with whiteleg shrimp on land, using a patent-pending technology


    Volta GreenTech
    https://www.voltagreentech.com/production/

    Volta Greentech is developing a scalable, sustainable, and automated land-based seaweed cultivation system - tailored for the selected species of seaweed that are crucial ingredients in Volta Seafeed. A land-based factory enables optimization of temperature, light, and nutrients to maximize the seaweed's growth rate while ensuring a high and standardized quality of the feed supplement.

    To meet the increasing global demand for the solution, we are rethinking how to produce seaweed at scale. Volta Seafeed has an immense impact potential, but as no one has been growing this type of seaweed at scale before, the global demand far exceeds the supply. Looking at existing production methods for seaweed, we quickly realized that we needed to take a different approach to reach the scale we are aiming for. Therefore, we went to the drawing board and looked at what would be necessary to produce Asparagopsis at scale for global implementation.

    ...

    The seaweed is grown in vertical bioreactors with sensors and automation in a controlled environment to maximize seaweed growth and quality to lower production costs

    Seawater is used as cultivation media and is naturally rich in nutrients. The seawater is recirculated in the system, and extra nutrients and CO2 are added to boost seaweed growth.

    The LED lights and the rest of the facility are powered by 100% renewable electricity. Waste heat from nearby industries is used to heat up the seawater and facility to the right cultivation temperature.

    LINKOS: 'Tráva je nutričně mnohem méně výživná než krmiva co pro ně pěstujem, proto se to tak dělá'
    pro koho?

    TADEAS: že intenzivní pěstování na ha má rozhodně vyšší výnos než když se tam ta kráva pase. Ano to je pravda.
    Že je sója z JA na krmiva a ne pro vegany, to je taky pravda.
    Tráva je nutričně mnohem méně výživná než krmiva co pro ně pěstujem, proto se to tak dělá. To je taky pravda.

    LINKOS: myslel jsem si, ze je v amazonii dulezitej celej ten cyklus, tzn. vytezit drevo, pak soja, pak zvirata jako posledni faze. mozna to tak i je, ale vypada to, ze to financujou cely hodne kvuli tem zviratum, coz jsem nevedel.

    urcite jsem to cely nikde neobhajoval :))

    kvuli veganum se to urcite nedeje, deje se to kvuli agroprumyslu, kterej dodava maso.

    a deje se to proto, ze nemanagujeme ekosystemy, ale produkujeme potraviny, coz je prilis reduktivni pristup k managementu ekosystemu.

    SHEFIK: ad 'Soybeans produce at least two times as much usable protein per acre than any other major vegetable or grain crop, except for hemp... They produce 5 to 10 times more protein per acre than land set aside for grazing animals to make milk, and up to 15 times more protein per acre than land set aside for meat production'

    tohle muze bejt pravda, ale zaroven je to az prilis zjednoduseny tabulkovy uvazovani. protoze ty land-uses nejsou volne konvertibilni.



    hezky to na vic mistech rozebira moje oblibena studie [fakt doporucuju, z hlediska zpusobu jak o tom celym premejslet]

    2016 Carrying capacity of U.S. agricultural land: Ten diet scenarios
    https://online.ucpress.edu/....elementa.000116/112904/Carrying-capacity-of-U-S-agricultural-land-Ten

    While livestock production is the largest land user on Earth, simplistic thinking about dietary change must be avoided (Herrero and Thornton, 2013). Reviews of life cycle assessments of livestock systems and protein products show, definitively, that land use per unit of protein is generally lower with plant than animal sources (de Vries and de Boer, 2010; Nijdam et al., 2012). However, they also demonstrate a wide range among individual livestock products and among different systems producing the same livestock product. In addition to this variability in area of land required, the quality of land required differs as well. Modeling studies suggest that the largest fraction of land needs for ruminant animals are from forages and grazing lands (Wirsenius et al., 2010; Peters et al., 2014), which are often grown on non-arable land. Thus, reducing the most land-intensive products in the diet does not necessarily equate to freeing up land for cultivation.

    TADEAS: a opět, protože tobě to asi nedochází - rozšiřování polí se sojou není kvůli veganům. Rozšiřování polí se sójou je protože se tím krmí zvířata. Je o dva odkazy níže kolik potřebuje prohnat bílkovin zvířetem, aby si dostal to samé množství v masu.

    Psal si, že kvůli chovu hospodářských zvířat se Amazonie nekácí a naznačovals, jako by za to mohli snad vegani. To je naprosto objektivní nepravda.

    btw treba soja je inspirativni v tom, ze pred 100 lety si nejaka mensi skupina farmaru rekla ze s tim neco udela a vyslechtila tuhle hyperplodinu.

    z hlediska regenerace a agrolesnictvi maj podobnej potencial lisky :) ... za par dekad muzeme mit produktivitu jako soja z hektaru, ale v uplne jinejch ekosystemovejch meritkach, tj. trvala plantaz, rozmanita genetika [ne klony], agrolesnickej [resp. agrokerovej] system, odolny proti ohni, nezavisly na pocasi danyho roku.
