Except the bulk of deforestation is not caused by locals needing space to live, but by big entrepreneurs investing in wood trafficking, soy plantations and livestock production.
I don't think that was the point of the OP though. It was more that even with people trying to protect the forest through legal means of property ownership, there's an apathetic, and sometimes antagonistic government that won't enforce that, and will even go so far as to help those entrepreneurs against owners trying to protect the forest.
After setting up a space to live, the invasion kept cutting down more jungle to sell the wood and turn it into farmland. This is when they lost their support. I'm not a journalist, though. I saw the clearings and town myself. The rest is stories I heard by the fire.
If anybody really knows how much deforestation is of what kind, they are not sharing it very publicly. Much less the economic power of the people doing it, so one can claim they are "big entrepreneurs".
Anyway, that thing on the link you posted is not a forest, and really not the Amazon.
This explosion of growth we are seeing is relatively recent, and is due not only to advances in technology, but also to cultural changes which may perhaps have been more important to enable this relentless expansion.
What was the most recognized traditional means to become rich if not by pillaging and military conquest? The idea that you could (and should!) become rich by individual economic effort was not common at all. To the contrary, it was frequently taken to be immoral, like the Medieval condemnation of usury, or the ostracism of rich people in Ancient Greece.
I recommend you take a look at the topics in Stanford's Encyclopedia of Philosophy and see if any subject matter interests you, and then use their bibliographic references for your readings:
Only in cataclysmic scenarios? I'm sorry to inform you, but in such scenarios most probably cryptos won't work either, as they all depend on proper working of the internet.
It doesn't even need to be a Madmax situation: just imagine a war between the US and China, with one of the involved causing an prolonged interruption in the communications between the two countries, as they have significant numbers of nodes/miners in most blockchains.
I'm afraid blockchains actually depend on the normal functioning of society with all its governmental structures in more ways than most crypto enthusiasts are ready to admit.
The US and Canada could block each other and it wouldn't affect Ethereum at all. Everyone in the world including those two countries could still use it.
