"Two theoretical physicists specializing in complex systems conclude
that global deforestation due to human activities is on track to trigger
the “irreversible collapse” of human civilization within the next two to
four decades.
If we continue destroying and degrading the world’s forests, Earth will
no longer be able to sustain a large human population, according to a
peer-reviewed paper published this May in Nature Scientific Reports.
They say that if the rate of deforestation continues, "all the forests
would disappear approximately in 100–200 years.”
"Clearly it is unrealistic to imagine that the human society would start
to be affected by the deforestation only when the last tree would be cut
down," they write.
This trajectory would make the collapse of human civilization take place
much earlier due to the escalating impacts of deforestation on the
planetary life-support systems necessary for human survival—including
carbon storage, oxygen production, soil conservation, water cycle
regulation, support for natural and human food systems, and homes for
countless species."
Via Irreverent Monk, who wrote "Shades of Asimov’s Foundation series.
But, with top soil depletion in 60 years, global warming heating up
places where a billion plus people live… Back in the 1980s, North
America was already seeing a 30% oxygen deficit (it’s made up by oxygen
generated by the oceans)."
