To my surprise, they say the sand in Sahara desert is being transported to Amazon rainforest by wind.
NASA Satellite Reveals How Much Saharan Dust Feeds Amazon’s Plants

Sahara desert is considered as once was a dense forest millions years ago.
There are some theories for the reason why it turned into desert.
One of them is a theory of “Earth experienced a dangerous tilt in axis about 84 million years ago”. Because of that dynamic and huge scale of the impact, Sahara could not keep its forest.
The Sahara swings between ‘lush’ and ‘desert’ every 20,000 years, in sync with the Earth’s tilt

So, substances that were essential to vegetation became sand.
In a cave around Florida, stalactites and stalagmites are found, that contain a layer of ash content. By chemically analyzing the layer, something detected is specific chemical components that is likely originated from vegetation in Sahara.
Then the layer can represent when the layer was formed.
From this finding, they guessed that there might have been large scale forest fire in Sahara. The timing then is found to be consistent with the start of desertification.
I forgot the exact article from which I learned it but here put the similar one as reference.
Stalagmites Help Scientists Trace Ancient Wildfires

African savanna was once a natural pasture field dense with grass for herbivores.
But the grass were almost lost, turning the field into savanna. Herbivores consumed the grass field into savanna.
So, what has recently been done by Human can also be the same as those done by nature. Therefore its only the matter of short term or long term, anyway eventually something would be lost after all. Then, why we have to preserve eco-system? It’s not necessary!
Oh ——– I am such an extremist!
Let’s see the difference between “By Human” and “By Nature”.
The example of Sahara, you see, its resource for sustaining bio-flourishing eco-system is now being transferred to Amazon rainforest. Maybe this flow of vitality is part of dynamic servo or feedback loop that is keeping any such shift within reversible balance..
Nature knows the precise balance for reversible.
In case of savanna, though an extent of grass field have disappeared, animals are surviving there. Maybe now balance between supply and demand have well been settled.
Probably, Nature knows here again “how”.
OK then, what about mass-extinction, our mother Earth have experienced so far?
Are they all being that balance state of reversible, or say sustainability?
After such mass-extinction, lifeform always were able to show its resilience. That’s why we are here on the earth right now.
All right, so if natural mass-extinction is permitted, then can another mass-extinction be allowed even if it is caused by human?
No matter how rapid the change is, everything destined to change and lost. Therefore, is there any point in keeping things as it is? Even if things get irreversible, being complete opposite of reversible state after natural mass-extinction, nevertheless there is nothing being forever. So, we do not need to care about anything like balance or reversible or sustainable.
I disagree with myself!
What matters most is our bond with nature. If we do not care about it then we will lose the meaning of ourselves. Nnnnnnn, I can’t have clear idea of justifying the superiority of “By Nature” against “By Human”. It’s like justifying the meaning of life like something conveyed by Albert Camus. Maybe the bond are the rock of Sisyphe.
Sorry Mr. Albert Camus, I just refer to your great work in this kind of idle talk.
Today, the theme of this article is now getting quite a bothering but I am able to insist that I love nature as presently is so I do not want to lose it, in my life at least, the beauty of nature found in Amazon Rainforest, Sahara Desert, Savanna field etc.
Oh another sip of sake can be the only salvation to me.
(Don’t drink too much of it anyway L.O.L)
