(TMU) – While 2020’s global pandemic has clearly revealed that the world is increasingly gripped by instability and social strife, the worst may only be yet to come as experts want that human civilization as a whole is fast approaching its “irreversible collapse” within the next 2 to 4 decades.
A new study published in peer-reviewed journal Scientific Reports has warned that if human economic activities continue at their present rate, our forests will become massively depleted and trigger the fall of civilization as we know it. And even the most optimistic forecast shows that there is less than a one in 10 chance that humans will be able to survive “without facing a catastrophic collapse.”
The research paper notes that if current deforestation trends around the world are allowed to continue, the planet’s very last forests could disappear in a matter of only 100 to 200 years – essentially rendering the Earth unable to sustain human populations.
And because humanity continues to rely on basic raw materials and food resources – not just for the sake of the world economic system but for basic survival – the crash could come in stages but would be unstoppable once forests are depleted beyond a certain point.
“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,” reads the study. “The progressive degradation of the environment due to deforestation would heavily affect human society and consequently the human collapse would start much earlier.”
According to the researchers, our window to prevent this terrible possibility could be closed within only 20 or 40 years.
Indeed, our successive civilizations have long relied on forests for many of the essentials of human life. As the study notes, trees play an essential role in planetary life-support systems ranging from carbon storage to oxygen production, water cycle regulation, oxygen production, support for natural and human food systems, habitats for a diverse range of species who also play a role in maintaining ecological health, and even the building material of our homes.
However, in the absence of forests, the paper reads, “it is highly unlikely to imagine the survival of many species, including ours, on Earth without them”
The research paper was written by theoretical physicists Dr. Gerardo Aquino from the Alan Turing Institute in the U.K. and Professor Mauro Bologna of the Department of Electronic Engineering at the University of Tarapacá in Chile, both of whom have long and accomplished careers as physicists.
Before the dawn of human civilization, the earth was covered in roughly 60 million square kilometers of fest. However, indiscriminate deforestation driven by human activities such as industrialization, clear-cutting of forest land, and urbanization has resulted in only 40 million square miles remaining.
However, while the paper clearly lays out the doomsday scenario in an impactful way, Motherboard notes that global deforestation rates have actually decreased in recent years. However, there has still been a net loss of forest land, and newly-planted trees are hardly a substitute for the old-growth forests and lush, biodiverse rainforests in regions like the Amazon.
“Calculations show that, maintaining the actual rate of population growth and resource consumption, in particular forest consumption, we have a few decades left before an irreversible collapse of our civilization,” the study concludes.
More than 5,000 baby seals wash up on Namibia beach in unprecedented die-off
Thousands of dead seal pups have washed ashore on the coast of Namibia, raising grave concerns from conservationist groups.
Locals were in shock after an estimated 5,000 premature cape fur seal pups washed up along the coast of Pelican Point peninsula, turning the popular tourist destination known for its thriving schools of dolphins and seal colonies into a pup graveyard.
Cape fur seals are often referred to as the “dogs of the ocean,” owing to their playful nature and abundant energy. However, the seals are known to desert their young or suffer miscarriages when food supplies are scarce.
The unprecedented die-off of the 5,000 Cape fur seals is now being probed by the country’s fisheries ministry, reports Bloomberg.
Nearly all were born prematurely before quickly dying, according to marine biologist Naude Dreyer of Ocean Conservation Namibia.
“When the pregnant female feels she does not have enough reserves, she can abort,” he explained. “A few premature deaths is a natural event, but thousands of premature dead pups is extremely rare.”
Dreyer noticed the masses of dead seal pups while flying his drone over the Pelican Point seal colony on Oct. 5.
“This is the situation at Pelican Point, Namibia,” his non-profit group wrote in a Facebook post. “All the little red circles mark dead seal pups. A rough estimate brings the numbers to more than 5,000 at our seal colony alone. This is tragic, as it makes up a large portion of the new pup arrivals expected in late November.”
The seals are commonly found across the southern Atlantic coastlines of the African continent, spanning Namibia and South Africa to the southern tip of Angola.
“Normally cape fur seals would give birth from mid-November until early December,” Dr. Tess Gridley told Africa News. “That’s the height of pupping that we would normally expect but what has been happening this year is there has been an increase in abortions that was first seen starting in August and really sort of peaked just last week in October.”
However, female cape fur seals are increasingly appearing emaciated and starving, raising alarm among conservationists about the long-term health of the typically thriving seal population.
“There are about 1.7 million cape fur seals in total and about a million of those are actually in Namibia so in terms of the overall number of animals, they are quite resilient to these effects,” Gridley explained.
“But one issue that we do think might happen in the future is you will see a dip in reproduction potentially going forward particularly now for those animals that have unfortunately died,” she continued. “They are not going to be recruited into the population, so you might see a localized effect at the Pelican Point colony and also we are trying to monitor to see whether there is a wider scale impact that might affect other colonies as well.”
An absence of fish in the region and the spread of disease and toxins in the water are among the possible reasons behind the die-off.
“The seals look a bit thin and it could likely be caused by a lack of food,” Dreyer said. “Other seal colonies at other beaches look much better and they do not record the same amount of premature pups.”
The Amazon rainforest is coming dangerously close to permanently converting into dry savannah
(TMU) – A vast swathe of the Amazon is teetering on the brink of disaster and risks crossing the tipping point of transforming from a closed canopy rainforest teeming with life to an open savannah with few trees as climate conditions deprive the region of rainfall and effectively kill its unique ecosystem, scientists have warned.
Rainforests are extremely sensitive to even the slightest changes in rainfall and moisture levels, and extended periods of drought and fire can be devastating in areas that rely on rain for sustenance. In the Amazon, such conditions would transform the lush rainforest into a semi-arid savannah-like mixture of woodland and grassland while also boosting the risk of fire.
While such dramatic changes to the Amazon were believed to be worst-case scenarios that could happen decades away, a team of Europe-based scientists warned on Monday that the tipping point is now dangerously close.
A new study published in the journal Nature Communications found that as much as 40 percent of the existing Amazon rainforest is already seeing so little rainfall that it could exist as a savannah-like environment, deprived of its canopy-like tree coverage and with far less biodiversity.
Researchers at the Stockholm Resilience Center used computer models and data analysis to stimulate the effect of continued climate change resulting from emissions from burning fossil fuels from now until the end of the century to find the results.
Rainforests typically create their own rainfall through water vapor, which then sustains and even extends the reach of tree levels.
However, when rain levels plummet, forest land also begins to fade away and degrade – resulting in a drier landscape that becomes more susceptible to the ravages of fire, drought, and ultimately, total deforestation.
The situation in the Amazon has only grown worse as Brazilian President Jair Bolsonaro has stubbornly pushed forward the opening of the rainforest to economic development, unleashing a wave of human-caused fires meant to illegally clear one of the region so that it can be exploited by miners, cattle ranchers, loggers, and big agricultural interests.
This year’s fires in the Brazilian Amazon are the worst in a decade, marking a dizzying 60 percent rise in fire hotspots compared to last year’s infamous blazes.
The rainforest is so delicate that even the most subtle changes in climate conditions can have an outsized impact on the ecological balance of the environment, said the study’s lead author, Arie Staal.
“As forests grow and spread across a region, this affects rainfall,” he told The Guardian. “Forests create their own rain because leaves give off water vapor and this falls as rain further downwind. Rainfall means fewer fires leading to even more forests.”
However, the loss of large areas of rainforest mean a precipitous drop in rainfall levels across the region.
“Drier conditions make it harder for the forest to recover and increase the flammability of the ecosystem,” Staal said.
At that point, the rainforest crosses a threshold and converts into a savannah-type environment – a conversion that is difficult, if not impossible, to reverse.
“It is harder to return from the ‘trap’ caused by the feedback mechanism in which the open, grassy ecosystem is more flammable, and the fires, in turn, keep the ecosystem open,” Staal said.
Experts have warned that the Amazon rainforest is a crucial barrier to the catastrophic breakdown of global climate conditions. Without the Amazon rainforest, carbon dioxide (CO2) emissions could become out of control and drive global warming to intolerable levels while the change in rainfall patterns could impact the entire Western Hemisphere.
Tragically, the loss of rainforests like the Amazon would also entail the extermination of a huge portion of global species.
“We understand now that rainforests on all continents are very sensitive to global change and can rapidly lose their ability to adapt,” said study co-author Ingo Fetzer of the Stockholm Research Center. “Once gone, their recovery will take many decades to return to their original state. And given that rainforests host the majority of all global species, all this will be forever lost.”
Hurricane Sally brings massive destruction to Gulf Coast in “epic proportion flooding event”
(TMU) – While Hurricane Sally has weakened to a tropical storm, it has also unleashed massive destruction on the Gulf Coast at a steady, drawn-out rate while bringing “catastrophic and life-threatening” flooding to the Florida Panhandle and southern Alabama, reports the National Hurricane Center.
A bruising storm surge and torrential rain has already demolished infrastructure, knocking down a section of the Pensacola Bay Bridge – also known as the Three-Mile Bridge – and inundating the city’s downtown in about 3 feet of rain while flooding neighborhoods, homes, and businesses across the region.

Authorities are urgently warning residents to flee however they can as high water vehicles and boats conduct rescue efforts to help people escape their flooded homes.
“We believe that this is an epic proportion flooding event,” Escambia County Public Safety Director Jason Rogers told WEAR. “There is extremely high water, moving water that is very dangerous. We don’t believe that we have yet seen the worst of the flooding.”

Sally, which managed to reach the level of a Category 2 hurricane with sustained winds of 105 mph, downgrade to a tropical storm early Wednesday after it made landfall near Gulf Shores, Alabama.
However, the storm’s impact remains deadly as winds hit 70 mph as of Wednesday afternoon while the eye of the storm was roughly 30 miles west-northwest of Pensacola.
Authorities are warning about the ferocity of the storm, which is creeping north-northeast at an excruciatingly grueling pace of only 5 mph, ensuring thorough destruction across the region as it threatens to potentially produce almost three feet of rain in areas as well as seven-foot-high storm surges, ensuring floods across the region.
“We anticipate the evacuations could literally be in the thousands,” warned Escambia County Sheriff David Morgan.
Upwards of half a million homes and businesses across Southern Alabama and the Florida panhandle had lost power as of Wednesday afternoon, according to poweroutage.us.
The National Weather Service declared a flash flood emergency for “severe threat to human life & catastrophic damage from a flash flood” The warning covers sections of coastal Alabama and the Florida Panhandle, as well as Gulf Shores and Pensacola.
Emergency services have been deluged by 911 calls across Alabama and Florida all Wednesday, according to several local governments, but first-responders have struggled to rescue residents due to the treacherous conditions, according to Santa Rosa County Public Safety Director Brad Baker.
Boats across the area have been crushed or unmoored amid the raging storm, with some boats being slammed into tourist shops and restaurants along marinas. One dramatic photo shared on Instagram showed a loose boat siting in the flooded courtyard of an Orange Beach condominium building, while flooded streets are filling up with debris and downed tree limbs.
Sally’s landfall came 16 years to the day since Category 3 Hurricane Ivan slammed the same area.
Many residents, well aware of the dangers of such storms, have prepared by purchasing essential supplies and preparing their generators for bruising storm surges.
However, the intensity and trajectory of the slow-moving tropical storm is likely to have unpredictable results.
