How to green the world’s deserts and reverse climate change | Allan Savory

Translator: Joseph Geni
Reviewer: Morton Bast
The most massive
tsunami perfect storm
is bearing down upon us.
This perfect storm
is mounting a grim reality, increasingly grim reality,
and we are facing that reality
with the full belief
that we can solve our problems with technology,
and that’s very understandable.
Now, this perfect storm that we are facing
is the result of our rising population,
rising towards 10 billion people,
land that is turning to desert,
and, of course, climate change.
Now there’s no question about it at all:
we will only solve the problem
of replacing fossil fuels with technology.
But fossil fuels, carbon — coal and gas —
are by no means the only thing
that is causing climate change.
is a fancy word for land that is turning to desert,
and this happens only when
we create too much bare ground.
There’s no other cause.
And I intend to focus
on most of the world’s land that is turning to desert.
But I have for you a very simple message
that offers more hope than you can imagine.
We have environments
where humidity is guaranteed throughout the year.
On those, it is almost impossible
to create vast areas of bare ground.
No matter what you do, nature covers it up so quickly.
And we have environments
where we have months of humidity
followed by months of dryness,
and that is where desertification is occurring.
Fortunately, with space technology now,
we can look at it from space,
and when we do, you can see the proportions fairly well.
Generally, what you see in green
is not desertifying,
and what you see in brown is,
and these are by far the greatest areas of the Earth.
About two thirds, I would guess, of the world is desertifying.
I took this picture in the Tihamah Desert
while 25 millimeters — that’s an inch of rain — was falling.
Think of it in terms of drums of water,
each containing 200 liters.
Over 1,000 drums of water fell on every hectare
of that land that day.
The next day, the land looked like this.
Where had that water gone?
Some of it ran off as flooding,
but most of the water that soaked into the soil
simply evaporated out again,
exactly as it does in your garden
if you leave the soil uncovered.
Now, because the fate of water and carbon
are tied to soil organic matter,
when we damage soils, you give off carbon.
Carbon goes back to the atmosphere.
Now you’re told over and over, repeatedly,
that desertification is only occurring
in arid and semi-arid areas of the world,
and that tall grasslands like this one
in high rainfall are of no consequence.
But if you do not look at grasslands but look down into them,
you find that most of the soil in that grassland
that you’ve just seen is bare and covered with a crust of algae,
leading to increased runoff and evaporation.
That is the cancer of desertification
that we do not recognize till its terminal form.
Now we know that desertification is caused by livestock,
mostly cattle, sheep and goats,
overgrazing the plants,
leaving the soil bare and giving off methane.
Almost everybody knows this,
from nobel laureates to golf caddies,
or was taught it, as I was.
Now, the environments like you see here,
dusty environments in Africa where I grew up,
and I loved wildlife,
and so I grew up hating livestock
because of the damage they were doing.
And then my university education as an ecologist
reinforced my beliefs.
Well, I have news for you.
We were once just as certain
that the world was flat.
We were wrong then, and we are wrong again.
And I want to invite you now
to come along on my journey of reeducation and discovery.
When I was a young man,
a young biologist in Africa,
I was involved in setting aside marvelous areas
as future national parks.
Now no sooner — this was in the 1950s —
and no sooner did we remove the hunting,
drum-beating people to protect the animals,
than the land began to deteriorate,
as you see in this park that we formed.
Now, no livestock were involved,
but suspecting that we had too many elephants now,
I did the research and I proved we had too many,
and I recommended that we would have to reduce their numbers
and bring them down to a level that the land could sustain.
Now, that was a terrible decision for me to have to make,
and it was political dynamite, frankly.
So our government formed a team of experts
to evaluate my research.
They did. They agreed with me,
and over the following years,
we shot 40,000 elephants to try to stop the damage.
And it got worse, not better.
Loving elephants as I do,
that was the saddest and greatest blunder of my life,
and I will carry that to my grave.
One good thing did come out of it.
It made me absolutely determined
to devote my life to finding solutions.
When I came to the United States, I got a shock,
to find national parks like this one
desertifying as badly as anything in Africa.
And there’d been no livestock on this land
for over 70 years.
And I found that American scientists
had no explanation for this
except that it is arid and natural.
So I then began looking
at all the research plots I could
over the whole of the Western United States
where cattle had been removed
to prove that it would stop desertification,
but I found the opposite,
as we see on this research station,
where this grassland that was green in 1961,
by 2002 had changed to that situation.
And the authors of the position paper on climate change
from which I obtained these pictures
attribute this change to “unknown processes.”
Clearly, we have never understood
what is causing desertification,
which has destroyed many civilizations
and now threatens us globally.
We have never understood it.
Take one square meter of soil
and make it bare like this is down here,
and I promise you, you will find it much colder at dawn
and much hotter at midday
than that same piece of ground if it’s just covered with litter,
plant litter.
You have changed the microclimate.
Now, by the time you are doing that
and increasing greatly the percentage of bare ground
on more than half the world’s land,
you are changing macroclimate.
But we have just simply not understood
why was it beginning to happen 10,000 years ago?
Why has it accelerated lately?
We had no understanding of that.
What we had failed to understand
was that these seasonal humidity environments of the world,
the soil and the vegetation
developed with very large numbers of grazing animals,
and that these grazing animals
developed with ferocious pack-hunting predators.
Now, the main defense against pack-hunting predators
is to get into herds,
and the larger the herd, the safer the individuals.
Now, large herds dung and urinate all over their own food,
and they have to keep moving,
and it was that movement
that prevented the overgrazing of plants,
while the periodic trampling
ensured good cover of the soil,
as we see where a herd has passed.
This picture is a typical seasonal grassland.
It has just come through four months of rain,
and it’s now going into eight months of dry season.
And watch the change as it goes into this long dry season.
Now, all of that grass you see aboveground
has to decay biologically
before the next growing season, and if it doesn’t,
the grassland and the soil begin to die.
Now, if it does not decay biologically,
it shifts to oxidation, which is a very slow process,
and this smothers and kills grasses,
leading to a shift to woody vegetation
and bare soil, releasing carbon.
To prevent that, we have traditionally used fire.
But fire also leaves the soil bare, releasing carbon,
and worse than that,
burning one hectare of grassland
gives off more, and more damaging, pollutants
than 6,000 cars.
And we are burning in Africa, every single year,
more than one billion hectares of grasslands,
and almost nobody is talking about it.
We justify the burning, as scientists,
because it does remove the dead material
and it allows the plants to grow.
Now, looking at this grassland of ours that has gone dry,
what could we do to keep that healthy?
And bear in mind, I’m talking of most of the world’s land now.
Okay? We cannot reduce animal numbers to rest it more
without causing desertification and climate change.
We cannot burn it without causing
desertification and climate change.
What are we going to do?
There is only one option,
I’ll repeat to you, only one option
left to climatologists and scientists,
and that is to do the unthinkable,
and to use livestock,
bunched and moving,
as a proxy for former herds and predators,
and mimic nature.
There is no other alternative left to mankind.
So let’s do that.
So on this bit of grassland, we’ll do it, but just in the foreground.
We’ll impact it very heavily with cattle to mimic nature,
and we’ve done so, and look at that.
All of that grass is now covering the soil
as dung, urine and litter or mulch,
as every one of the gardeners amongst you would understand,
and that soil is ready to absorb and hold the rain,
to store carbon, and to break down methane.
And we did that,
without using fire to damage the soil,
and the plants are free to grow.
When I first realized
that we had no option as scientists
but to use much-vilified livestock
to address climate change and desertification,
I was faced with a real dilemma.
How were we to do it?
We’d had 10,000 years of extremely knowledgeable pastoralists
bunching and moving their animals,
but they had created the great manmade deserts of the world.
Then we’d had 100 years of modern rain science,
and that had accelerated desertification,
as we first discovered in Africa
and then confirmed in the United States,
and as you see in this picture
of land managed by the federal government.
Clearly more was needed
than bunching and moving the animals,
and humans, over thousands of years,
had never been able to deal with nature’s complexity.
But we biologists and ecologists
had never tackled anything as complex as this.
So rather than reinvent the wheel,
I began studying other professions to see if anybody had.
And I found there were planning techniques
that I could take and adapt to our biological need,
and from those I developed what we call
holistic management and planned grazing,
a planning process,
and that does address all of nature’s complexity
and our social, environmental, economic complexity.
Today, we have young women like this one
teaching villages in Africa
how to put their animals together into larger herds,
plan their grazing to mimic nature,
and where we have them hold their animals overnight —
we run them in a predator-friendly manner,
because we have a lot of lands, and so on —
and where they do this and hold them overnight
to prepare the crop fields,
we are getting very great increases in crop yield as well.
Let’s look at some results.
This is land close to land that we manage in Zimbabwe.
It has just come through four months of very good rains
it got that year, and it’s going into the long dry season.
But as you can see, all of that rain, almost of all it,
has evaporated from the soil surface.
Their river is dry despite the rain just having ended,
and we have 150,000 people
on almost permanent food aid.
Now let’s go to our land nearby on the same day,
with the same rainfall, and look at that.
Our river is flowing and healthy and clean.
It’s fine.
The production of grass, shrubs, trees, wildlife,
everything is now more productive,
and we have virtually no fear of dry years.
And we did that by increasing the cattle and goats
400 percent,
planning the grazing to mimic nature
and integrate them with all the elephants, buffalo,
giraffe and other animals that we have.
But before we began, our land looked like that.
This site was bare and eroding for over 30 years
regardless of what rain we got.
Okay? Watch the marked tree and see the change
as we use livestock to mimic nature.
This was another site
where it had been bare and eroding,
and at the base of the marked small tree,
we had lost over 30 centimeters of soil. Okay?
And again, watch the change
just using livestock to mimic nature.
And there are fallen trees in there now,
because the better land is now attracting elephants, etc.
This land in Mexico was in terrible condition,
and I’ve had to mark the hill
because the change is so profound.
I began helping a family in the Karoo Desert in the 1970s
turn the desert that you see on the right there
back to grassland,
and thankfully, now their grandchildren are on the land
with hope for the future.
And look at the amazing change in this one,
where that gully has completely healed
using nothing but livestock mimicking nature,
and once more, we have the third generation of that family
on that land with their flag still flying.
The vast grasslands of Patagonia
are turning to desert as you see here.
The man in the middle is an Argentinian researcher,
and he has documented the steady decline of that land
over the years as they kept reducing sheep numbers.
They put 25,000 sheep in one flock,
really mimicking nature now with planned grazing,
and they have documented a 50-percent increase
in the production of the land in the first year.
We now have in the violent Horn of Africa
pastoralists planning their grazing to mimic nature
and openly saying it is the only hope they have
of saving their families and saving their culture.
Ninety-five percent of that land
can only feed people from animals.
I remind you that I am talking about
most of the world’s land here that controls our fate,
including the most violent region of the world,
where only animals can feed people
from about 95 percent of the land.
What we are doing globally is causing climate change
as much as, I believe, fossil fuels,
and maybe more than fossil fuels.
But worse than that, it is causing hunger, poverty,
violence, social breakdown and war,
and as I am talking to you,
millions of men, women and children
are suffering and dying.
And if this continues,
we are unlikely to be able to stop the climate changing,
even after we have eliminated the use of fossil fuels.
I believe I’ve shown you how we can work with nature
at very low cost
to reverse all this.
We are already doing so
on about 15 million hectares
on five continents,
and people who understand
far more about carbon than I do
calculate that, for illustrative purposes,
if we do what I am showing you here,
we can take enough carbon out of the atmosphere
and safely store it in the grassland soils
for thousands of years,
and if we just do that on about half the world’s grasslands
that I’ve shown you,
we can take us back to pre-industrial levels,
while feeding people.
I can think of almost nothing
that offers more hope for our planet,
for your children,
and their children, and all of humanity.
Thank you.
Thank you. (Applause)
Thank you, Chris.
Chris Anderson: Thank you. I have,
and I’m sure everyone here has,
A) a hundred questions, B) wants to hug you.
I’m just going to ask you one quick question.
When you first start this and you bring in a flock of animals,
it’s desert. What do they eat? How does that part work?
How do you start?
Allan Savory: Well, we have done this for a long time,
and the only time we have ever had to provide any feed
is during mine reclamation,
where it’s 100 percent bare.
But many years ago, we took the worst land in Zimbabwe,
where I offered a £5 note
in a hundred-mile drive
if somebody could find one grass
in a hundred-mile drive,
and on that, we trebled the stocking rate,
the number of animals, in the first year with no feeding,
just by the movement, mimicking nature,
and using a sigmoid curve, that principle.
It’s a little bit technical to explain here, but just that.
CA: Well, I would love to — I mean, this such an interesting and important idea.
The best people on our blog are going to come and talk to you
and try and — I want to get more on this
that we could share along with the talk.AS: Wonderful.
CA: That is an astonishing talk, truly an astonishing talk,
and I think you heard that we all are cheering you on your way.
Thank you so much.AS: Well, thank you. Thank you. Thank you, Chris.

  1. We brought back the buffalo. I agree with you but some are using this as an excuse to burn the rain forest. We also need trees and forest. We have cut all those down and need to replace them.

  2. He is probably right about how to make the land green but it's not co² from plants that heat the earth.
    We know this since plants has some C14 but that has not increased, it's included in the normal carbon flux. But it's interesting and it can also be used as argument for those who will save the wolfs that people only see as pest. They may prevent elks and deers to stay on the same spot too long.

  3. Any one that thinks Humans have the power to effect the climate on this planet is seriously deluded. Humans do NOT have the power to create an Extinction Level Event (ELE). The forces and time scales involved are way beyond Human capacity. On the 13th of April 2029 you might find out what can and does change the climate. Apophis is its' name. It should come within about 30,000 Km. About 1/12 of the distance to the moon. If something influences the orbit of Apophis by a tiny fraction of a degree then we have an impact. Another ticking time bomb is Yellowstone. If this went off with a VEI of 8 the entire planet would be poisoned and frozen. Supervolcano called Toba in Indonesia blew up 74,000 years ago with a VEI of 8. There were somewhere between 600 and 10,000 Humans left on this planet. We came within a gnats whisker of extinction.

  4. Indian farmers have been using this since forever to improve farm productivity. The owner of life-stocks are paid by farmers to make the herd of animals "sit-in" in the farm land. I'm surprised, this effect had to be rediscovered like that.

  5. Fantastic research and brilliant results. Nobody ever talks about the taboo of reducing the worlds human population though? Imagine what a better place the world would be with our population gradually reduced to 5 billion humans instead of 10 billion.

  6. The problem isn't fossil fuels but with the exponential rise in population! No one is addressing this and to LIMIT population growth!

  7. This actually wouldn't help climate change, estimates put it at a 25% reduction in carbon in the atmosphere at today's levels…. But it would take 4 decades minimal to get this to that number using water desalination plants, but building and fueling those plants would cause more damage to the planet that this would help, using livestock also hurts the atmosphere and would take tens of thousands of people hundreds of years to do.

  8. I hope he doesn't decide there are too many humans on the planet. We'll all be shot. Later, he could regret it and take his sorrow to the grave, but the rest of us will already be there waiting for him.

  9. Greening the desert is easy, just load the atmosphere with 1000 ppm of CO2. Just as greenhouse gardners do with the greenhouses

  10. climate change is a conspiracy theory by government tyrants to spread fear mongering among the ignorant population so they can impose a carbon tax….stupid much?

  11. Why don't the Dem-o-Craps START by rounding up all ILLEGAL guns before attacking innocent 2nd amendment rights ??? Also this is not a "democratic" debate it is a "Democrat" debate. Nothing about these morons is democratic. Hill-ray will be back.


  12. Frozen lands turning to farm land is outpacing farmland to desert, crop yields are setting records. It is the cold that destroys more than heat and its not even close.

  13. This is a great idea, but he is missing a large point, CO2 is NOT the enemy.Do you want the earth to look like mars? Keep reducing CO2 and thats exactly what you will have. When CO2 reaches 180 PPM we will be on the verge of human extinction. We are at 400-415, we are so close to killing ourselves its unreal. CO2 actually increases plant yields, accelerates "re-greening" and improves reforestation of the planet. Those that call this a Myth are lairs and /or do not understand the developmental process in which plant growth is stimulated. More "Fake News" The earth produced the largest plants along with giving the largest diversity of plant life that the largest animals that ever existed lived, the dinosaurs. CO2 was 5000 to 10,000 PPM Greed has created a problem reaction solution social game and with the help of the blackmailed scientific community creating the foundation it has spread into a false fear based illusion to extort money through taxation and handing over more governmental and corporate control. For more : and

  14. Just about any gardner knows that when you put animals such as chickens, sheep ,cattle ..or wild animals on land ..they will fertlize the soil with their "waste " and by eating part of  the plants ..these plants will grow bigger and faster ….

  15. if this isn’t proof nature knows exactly what it’s doing, i don’t know what is. it’s like it’s intelligent, like it was created by something intelligent…because it was.

  16. So in other words this dumbass has gone full circle. He took cattle out of the equation, doing so he wiped out the land and 40 thousand elephants (which are on the endangered species list) and then realized the cattle were good for the land.
    He’s done more damage to the planet than he could ever repay, the starvation in his country, the death of some of the most magnificent creatures on earth and yet, he’s still lecturing about what he thinks, he obviously is a flawed thinker and the world would be better off had he gone into the janitor business. The saddest part is, he’s not alone, there are more boneheaded scientists like him that are damaging our planet at alarming rates, yet we are the ones they try and blame.
    There are some pretty smart people in the scientific community, he’s obviously not one of them.

  17. @Allansavory the only thing missing for me was measurements of CO2. Is the soil reclamation lowering carbon emissions, and if so, how, and is there any realistic way to measure how much carbon is reclaimed/sequestered by the reclaimed grasslands? In other words, how does the soil reclamation method you explain help to slow global warming?

  18. I applaud any scientist who is willing to admit his theory is wrong. Congratulations for finding that livestock are not harmful, and also finding a simple solution to what is a significant problem.

    Now I would implore you to rethink the popular assumptions that carbon is poison and carbon dioxide is pollution. Carbon is the building-block element for all animal and plant life on earth. The scientific definition of "organic" is something that contains carbon, and i,s or was at one time, a living organism.

    And carbon dioxide is a crucial molecule which all plant life on earth "breathe." It is as crucial to them as oxygen is to humans and all animal life. In America, we have experienced the most green, lush and beautiful Summer in recent history. Not only has CO2 not harmed our environment, its seeming abundance have resulted in the exact opposite.

    The fear and anxiety produced by actors and politicians over climate change is significant and harmful.

  19. We need to mass develop this idea so as to cover the entire Earth. Pure genius and great use of the First Principle to deduce seemingly counterintuitive ideas

  20. Aún no termino de ver la conferencia sin embargo no estoy de acuerdo con lo que dice del ganado en el minuto 4:14 no es culpa del ganado, es culpa del propio humano que no sabe nada sobre el pastoreo. Esto afecta el suelo, más no el ganado.

  21. I’m willing to bet that CO2 has played a role in the greening of the earth. NASA satisfies have shown the expanding of aired areas.

    CO2 is the building block for life. From oxygen to water, plant growth, higher yields at harvest time.

    Solar cycles and the number of flares or sunspots have been the greatest determinate of our climate. Research solar cycle 14-17. Take note of the third year in solar cycle 17.

  22. A fine example of true science being used for the benefit not just of the elite with the benefits of the people of those countries a fine example of our real science works in the real world

  23. so keeping in mind Brazil’s new President, Jair Bolsonaro, an unapologetic exploitation of the Amazon – since his inauguration in January, the rate of deforestation has soared by as much as 92%, according to satellite imaging. ack – STOP! What is happening to the earth by human hands IS NOT NATURAL and it WILL be the death of humanity! Start listening to Scientists – there are real things we can do to manage it properly for all humans not just the 1%!

  24. That weird global map portion is really wrong. a huge part of that is going into the Russia and even my hometown Novosibirsk. Which is a really woody, humid and cold area. I understand trying to get your point across about how important this is. Though it's obvious this is very motive driven and that takes away a lot of your punch.

    Anyways, it's nice to see we can stop deserts.

  25. So are cow farts going to kill us or save us? The only thing that can be said about scientist is that they are always the first to be wrong about everything.

  26. To what extent would the Albedo effect offset the gains in terms of global warming? Not a reason to deny these regions the benefits of vegetation, but still an important question. Moreover, increased livestock will increase atmospheric methane concentrations (and methane is a more potent greenhouse than CO2). But anyway, afforestation has been the subject of interest for many years, but for some reason the idea never gained traction, even though it's probably the most cost effective carbon sequestration technique available.

  27. Lmao. Same old crap. Climate change is a hoax fact. The earth does not have to many ppl fact. They are lieing. That's an these clowns know.

  28. Geoengineering never works and every time the European interferes with natures will you always have traumatic consequences the white men needs to leave well enough alone, nature will decide the fate of this planet

  29. climate change utter bullshit the earth has heated up and cooled down over the last 1000s of years had it happen in the last 200 years had written accounts from the thames river had a market on the ice every year then warmed up ,the earth needs carbon monoxide without it we die ,these folks go on and on whats the catch ? land cant feed folks then folks need to stop haveing kids too many of us we leave the planet it will heal all by its self she dont need us

  30. Going to leave this here too. Droughts in Australia are devastating the landscape and again it is some people on the land that have proven how to manage flood plains through drought cycles, again mimicking natural processes.

  31. In Pakistan, they planted 1 billion trees in a matter of a year or so. Pakistan has been hit real hard by climate change with extreme melting of glaciers. Pakistan has the world's largest number of glaciers, 10,000 of them and they are all melting fast. Every nation can do the same…. It's fairly easy, and armies of volunteers can be mobilized via social media apps.

  32. "We though desertification was caused by elephants…We had too many elephants, so we decided to shot dead 40,000 Elephants… but unfortunately was a mistake…"

  33. Nature has its own cause. Follow the cause, the balance force is right there. 14K ? ? because of a research ? proposal is not a little lesson. Now mimic the nature?️ instead, a good thing at least we can try.

  34. I was only commenting on the ideas to repair damage to the earth…. we humans create too much bare ground. What people eat is not really the issue. How we treat the earth is. If you think that you’re always helping the planet with a vegan diet, you may want to think again!!

  35. Why isn't this being trumpeted from the highest heights. This man is a saviour. Hail and honour him. Heed him or be damned. I wish my dad could've seen this.

  36. BLOWN AWAY! Well, if this isn't one of the most important revelations humanity could have right now, aside from God, I don't know what is! WOW!

  37. Better yet why not make fish grow legs idiot… its all junk scidnce pure and simple but seeing youre attitude you are a
    Abject blithering idiot you're self
    You could spend you're
    entire life trying to distroy his planet and you would fail miserably
    Nature will out live us all
    Except for those with the brains of a retarded GOAT

  38. Ok that's great as it undergo desertification, but why does he says nothing about enteric methane emited by ruminants. I want to know if the greenhouse gas emited by holistic grazing could really make its carbon footprint negative.

  39. Thousands of livestock die in the desert's of Australia every time there is a drought but apparently when you introduce livestock in huge quantities to barren land they don't need to be fed.. mmmmm. Australia is also a perfect case study in that livestock production is only 200 years old and we have the highest rate of mammal extinction in the world. Sigmoid Curve is not very complicated it just means that that initial growth in a healthy environment/ system is not linear and that it accelerates over time – i find it hard to see how introducing the livestock in greater numbers can reverse the desertification and destruction of the Australian landscape when it is the primary cause. Further as a South African this man's ideas around "culling" resulted in the deaths of 40,000 Elephants – just think about how much that affected the natural balance. I love the idea of sustainable practice but livestock and meat consumption in a world of 7 Billion people is a fantasy.

  40. Also, use a few SoilKee Renovators:

  41. You can't REVERESE climate change. Mankind has zero impact on climate change. Man has not created climate change. It's a scam, a hoax. Climate change is a perfectly natural phenomenon. The world heats and cools and heats and cools. It currently is beginning it's warm season. Perfectly natural, and organic. Nothing whatsoever to do with man.

  42. According to climate scientists he is wrong on CO2. Prof Happer, one of the leading scientists on the subject states, that contrary to the alarmists, the world has a CO2 FAMINE. On everything else he is almost certainly correct, but he has a battle on his hands with the vegan / vegetarian community, who want to do away with farm animals.

  43. "What's that? My credentials? I was an ecologist and had 40,000 elephants shot 'cus of some theory I had… now let me explain my new theory!"

  44. This is along the same line as our "fire management" of the forests of North America. Always putting out every fire makes it a haven for super fires. We have learned that mimicking nature is the best course.

  45. Australian native tribes have conducted large scale annual rotating burn offs in the arid desert and semi desert grass lands for 40,000 years . They know that this is good for the health of the land .

  46. the solution to mankind's actions is quite simple. whether or not we'll be able to learn, and apply it, remains the question…..

  47. There is a much better and permanent solution to this. he stated his opinion as fact. Thank god government is not listening. We can turn the land into forests
    This man is literally too dumb to have tried comparing and observing types of growths. A scourge upon the Earth

  48. It is not possible for mankind to reverse climate change. There is NO VALID PHYSICS that can be used to explain ANY warming by carbon dioxide, water vapor or methane etc. Learn why:
