    I already wrote to your similar question that the premise that we *need* copper, chromium, nickel, tin and tungsten is already wrong.
    We (and/or our food species + symbiotes) need only trace amounts of
    copper, chromium and nickel, there are way more of it in nature around
    us than any imaginable size of population needs. Tin and tungsten are
    not known to be needed.

    If it wasn't covered before, we "need" vitamins
    in our diet that other living things produce
    in their own organism, maybe needing them
    in the sane way that we do. It seems that we
    /had/ a gene for making our own Vitamin C,
    it's still there, but it doesn't work any more.

    Some substances, it is hard to see how biology
    could work if they didn't exist. But many
    substances that human biology currently
    relies on, if they had never been available
    then our bodies could have become very
    much what they now are by using a different
    chemistry instead. For that matter, conceivably
    a better biology than ours could have been
    designed, and we would have been out-competed,
    except for the absence of a designer.

    Then again, maybe dodos thought like that
    about their place in the world. And now
    we're here and they are not.

    We don't really "need" most of it. But living in some cyberpunk toxic
    wasteland would be sad. So we should not allow thriftless misuse
    and mismanagement of our resources/riches. Like I've already said
    most of problems with it is because of wasting.

    Nature is not damaged by population but heartless greed-based
    industries.
    Look in Africa ... one business took land to cut down forest, other
    overtook to grow oil palms there then third came to use it for (or
    to block others from) mining something. Result is disappeared
    forest, burned down palm plantation and extinction of lot of local
    species.

    Local people live anyway in bad poorness in huts made of clay mixed
    with cattle dung, they got nothing from those "deals". Their country
    competes in "poorest" lists. Some get killed or wounded as the
    "business" there is often violence-based. It is not Russian "Wagner
    Group" dealing there anymore ... Yevgeny Prigozhin is dead.

    Then lets look from here. Whatever the industries gained there
    cheaply, wastefully and unfairly they manufactured some horrible
    "goods" from it perhaps using child labor in somewhere. Those
    "goods" are designed to deteriorate and break down soon.

    All the damn retail "super" markets are full of those "goods". If you
    kept the cheques then can easily find reason to require replacement
    1 to 4 times during up to 2 year warranty. If not, just throw it away
    and buy new one ... will be at least as shitty.

    All that trash then goes to "landfill". Oh so sweet way to "fill the land" indeed. Licence to manufacture and to sell should be taken away
    from Apple, Intel, Huawei, Sony, Dell, Samsung, Lenovo etc. and
    people who organised that insanity should be personally sent to
    manually recycle the trash and repair the damage done to nature.

    Depends what times you compare to get that "double". 10000 years ago
    Sahara was all savanna, 100 years ago it was "only" 10% smaller.
    Were these really locals or overall climate change? Hot weather just
    dries everything out, chlorophyll stops working around 45°C and
    water is anyway needed to make glucose from water + carbon dioxide.

    If it wasn't covered before, we "need" vitamins
    in our diet that other living things produce
    in their own organism, maybe needing them
    in the sane way that we do. It seems that we
    /had/ a gene for making our own Vitamin C,
    it's still there, but it doesn't work any more.

    Some substances, it is hard to see how biology
    could work if they didn't exist. But many
    substances that human biology currently
    relies on, if they had never been available
    then our bodies could have become very
    much what they now are by using a different
    chemistry instead. For that matter, conceivably
    a better biology than ours could have been
    designed, and we would have been out-competed,
    except for the absence of a designer.

    Then again, maybe dodos thought like that
    about their place in the world. And now
    we're here and they are not.

    Not entirely true. By the 1970s, the Sahara had doubled in size not due
    to industry, but because pastoralists on its edges kept cutting down
    whatever plant life they found for firewood.

    Depends what times you compare to get that "double". 10000 years ago
    Sahara was all savanna, 100 years ago it was "only" 10% smaller.
    Were these really locals or overall climate change? Hot weather just
    dries everything out, chlorophyll stops working around 45°C and
    water is anyway needed to make glucose from water + carbon dioxide.

    Climate warming was not significant by the 1970s. The doubling in the
    Sahara Desert's area in the 20th century was human-caused.

    Let me try again?
    Claim of size growth of desert takes two dates.
    Without it "doubling by 1970" makes no sense. Should I assume from 1900?
    Yet between 1920 and 2018 growth of Sahara has been about 10% or at
    least so that propaganda site of an evil imperialist country tells: <https://www.nsf.gov/news/news_summ.jsp?cntn_id=244804>
    So how there was doubling between 1900 and 1970?
    When the bad local people did collect all plants on 1,5 million of square
    miles to turn it into 3,5 square miles it currently is?

    I've read that big part of its desertification during last 10,000 years explained by the Earth "wobbling" on its axis. So by that how where
    the Earth points moves in a circular fashion every 26,000 years and
    so causing wetter or dryer North Africa. It can be of course also
    wrong story, I don't know.

    I wanted to become forest ranger in youth but figured that it does not help. So then I tried to help biotechnological equipment manufacturers but saw that
    they are also using it more for to spoil things. So I've put big part of my last
    two decades into helping to make electric motors, solar batteries, wind generators and heat pumps more efficient and better controlled. I still love nature, still read articles about biology and still prefer to walk to my workplace instead of driving a car. Prudence towards nature has gradually become more popular here in Europe. There are still those who go madly
    too far with their tree hugging and plenty of those who just slyly "green
    wash" their garbage but it is fact that our next generations have no better place to escape.

    Without it "doubling by 1970" makes no sense. Should I assume from 1900?
    Yet between 1920 and 2018 growth of Sahara has been about 10% or at
    least so that propaganda site of an evil imperialist country tells: <https://www.nsf.gov/news/news_summ.jsp?cntn_id=244804>
    So how there was doubling between 1900 and 1970?
    When the bad local people did collect all plants on 1,5 million of square miles to turn it into 3,5 square miles it currently is?

    I've read that big part of its desertification during last 10,000 years explained by the Earth "wobbling" on its axis. So by that how where
    the Earth points moves in a circular fashion every 26,000 years and
    so causing wetter or dryer North Africa. It can be of course also
    wrong story, I don't know.

    I may have misremembered the number, or perhaps the writers of the
    article I'm think of (circa 1977 in the _Bulletin of the Atomic
    Scientists_) were using different standards of measurement. There's no hard-and-fast line delimiting where the desert ends, and they may have
    been including the desertification which is causing famines in the
    Sahel. At any rate, the desertification is certainly man-made, mostly
    from fuel gathering, and it has affected a very large area and continues
    to grow.

    My impression from both memory and cursory research just now is that the
    Sahara has been mostly unaffected by climate changes since at least 2000
    BCE until rising temperatures starting roughly in the 1980s or 1990s. I further doubt that human impact was severe before industrialization and
    modern medicines, so I would guess that the starting time for the
    doubling (if it was that) would be about 1850.

    If it wasn't covered before, we "need" vitamins
    in our diet that other living things produce
    in their own organism, maybe needing them
    in the sane way that we do. It seems that we
    /had/ a gene for making our own Vitamin C,
    it's still there, but it doesn't work any more.

    Some substances, it is hard to see how biology
    could work if they didn't exist. But many
    substances that human biology currently
    relies on, if they had never been available
    then our bodies could have become very
    much what they now are by using a different
    chemistry instead. For that matter, conceivably
    a better biology than ours could have been
    designed, and we would have been out-competed,
    except for the absence of a designer.

    Then again, maybe dodos thought like that
    about their place in the world. And now
    we're here and they are not.

    Depends what times you compare to get that "double". 10000 years ago
    Sahara was all savanna, 100 years ago it was "only" 10% smaller.
    Were these really locals or overall climate change? Hot weather just
    dries everything out, chlorophyll stops working around 45°C and
    water is anyway needed to make glucose from water + carbon dioxide.

    Climate warming was not significant by the 1970s. The doubling in the
    Sahara Desert's area in the 20th century was human-caused.

    Sahel.

    There may be indeed different definitions. Still I can find no such drastic studies. For example this study that uses less than 100 mm/year of rainfall
    as desert definition ... <https://www2.atmos.umd.edu/~nigam/Desert.Biome.Final.published.Nigam-Thomas.16October2019>
    ... gets even smaller than 10% change:
    "The Sahara Desert has expanded by 2–4% over 1920–2016."
    So by what standard there was that almost doubling between
    1850 and 1920? Can be you misremembered indeed.

    My understanding so far was that 10,000 years ago Sahara was all forested savanna. That humid period ended around 6,000–5,000 years ago leading to severe "pan-tropical environment change" (IOW drought) and about 4,000
    years ago that caused collapses of civilisations in Africa, Asia and Middle East.

    At any rate, the desertification is certainly man-made, mostly
    from fuel gathering, and it has affected a very large area and continues
    to grow.

    That was rather recent massive metallurgy -> lot of forests cut out -> massive coal and petroleum mining and transportation with the new iron toys.
    That caused current greenhouse, some overall heating and drying.
    But so short effect has resulted with perhaps 5-15% of growth of Sahara
    and desertification in other parts of planet too.
    That is also huge, 5-15% of Sahara is like 10 to 30 territories of Estonia. OTOH beduin herders being in difficulty to find wood for cooking and
    warming their tent at night sounds clearly like an outcome of it not cause.

    My impression from both memory and cursory research just now is that the Sahara has been mostly unaffected by climate changes since at least 2000
    BCE until rising temperatures starting roughly in the 1980s or 1990s. I further doubt that human impact was severe before industrialization and modern medicines, so I would guess that the starting time for the
    doubling (if it was that) would be about 1850.

    Yes that 2000 BCE is the 4000 years ago. There sure were some further developments between 4000 ya and 2000 ya in that huge region, lot of it is probably studied. Lakes becoming more and more salty and drying out entirely, vegetation changing etc. that all goes slowly and leaves evidence.
    Nature can change very rapidly only when humans redirect or close whole rivers, cut out whole forests, make large farmlands. Those remarkable projects always go with significant propaganda and investments. Sudden sharp jump between
    1850 and 1920 because people gathering firewood just does not fit with
    how anything works on this planet.
