(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.

Scientists Thrilled by Discovery of Rare, Mammoth 400-Year-Old Coral

A massive 400-year-old hard coral discovered on the Great Barrier Reef has scientists expressing their sense of surprise and excitement.

Named Muga dambhi by the Manbarra people, the Indigenous group who have traditionally taken care of the land, the “exceptionally large” brown and cream-colored coral is located off the coast of Goolboodi or Orpheus Island in the Great Barrier Reef.

It is believed that the coral was spawned some 421 to 438 years ago, meaning that its age predates the arrival of Captain James Cook and the advent of colonization in Australia, notes the Guardian.

The spectacular coral is about 35 feet wide and over 17 feet high, and is double the size of the nearest coral.

Scientists and members of the community participating in a marine science course discovered the specimen earlier this year.

While not the largest coral in the world, the huge find is of major significance to the local ecosystem, according to Adam Smith, an adjunct professor at James Cook University who wrote the field note on the find.

“It’s like a block of apartments,” Smith said. “It attracts other species. There’s other corals, there’s fish, there’s other animals around that use it for shelter or for feeding, so it’s pretty important for them.”

“It’s a bit like finding a giant redwood tree in the middle of a botanic gardens,” he added.

It is likely that the coral hasn’t been discovered for such a long time due to its location in a relatively remote and unvisited portion of a Marine National Park zone that enjoys a high degree of protection.

“Over the last 20 or 30 years, no one has noticed, or observed, or thought it newsworthy enough to share photos, or document, or do research on this giant coral,” Smith said.

The coral is in remarkable condition, with over 70 percent of its surface covered in live coral, coral rock and microalgae. No disease, bleaching or recently deceased coral has been recorded on the specimen.

“The cumulative impact of almost 100 bleaching events and up to 80 major cyclones over a period of four centuries, plus declining nearshore water quality contextualise the high resilience of this Porites coral,” the field note added.

The specific coral has been given the name Muga dhambi, meaning big coral, out of respect for the Indigenous knowledge, language, and culture of the Manbarra Traditional Owners.

Greenland Ice Washed Away as Summit Sees Rain for First Time in Recorded History

For the first time in recorded history, torrential downpours of rain have struck Greenland’s icy summit nearly two miles above sea level.

Greenland, an environmentally sensitive island, is typically known for its majestic ice sheet and snowy climate, but this is fast changing due to a massive melt taking place this summer.

However, the typical snowfall has been replaced in recent years not simply by a few showers, but by heavy rainfall. The torrential downpour last week was so huge, in fact, that it washed away a terrifying amount of ice across some 337,000 square miles of the ice shelf’s surface, reports Earther.

Temperatures at the ice shelf had simultaneously warmed to a significant degree, with the summit reaching 33 degrees Fahrenheit – within a degree above freezing and the third time that the shelf has surpassed freezing temperatures this decade.

The fact that rain is falling on ice rather than snow is also significant because it is melting ice across much of southern Greenland, which already saw huge melting events last month, while hastening rising sea levels that threaten to submerge whole coastal cities and communities.

To make matters worse, any new ice formed by the freezing rainwater will not last long. The ice shelf currently existing on Greenland was formed by the compression of snow over innumerable years, which shines bright white and reflects sunlight away rather than absorbing it, as ice from frozen rain does.

The huge scale of the melt and accompanying rainfall illustrate the growing peril of rapidly warming climate conditions across the globe.

“This event by itself does not have a huge impact, but it’s indicative of the increasing extent, duration, and intensity of melting on Greenland,” wrote Ted Scambos, a senior research scientist at the National Snow and Ice Data Center at the University of Colorado. “Like the heat wave in the [U.S. Pacific] northwest, it’s something that’s hard to imagine without the influence of global climate change.”

“Greenland, like the rest of the world, is changing,” Scambos told the Washington Post. “We now see three melting events in a decade in Greenland — and before 1990, that happened about once every 150 years. And now rainfall: in an area where rain never fell.”

South Korean Toilet Turns Poo Into Green Energy and Pays Its Users Digital Cash

What if your morning #2 not only powered your stove to cook your eggs, but also allowed you to pay for your coffee and pastry on the way to class?

It seems like an absurd question, but one university in South Korea has invented a toilet that allows human excrement to not only be used for clean power, but also dumps a bit of digital currency into your wallet that can be exchanged for some fruit or cup noodles at the campus canteen, reports Reuters.

The BeeVi toilet – short for Bee-Vision – was designed by urban and environmental engineering professor Cho Jae-weon of the Ulsan National Institute of Science and Technology (UNIST), and is meant to not only save resources but also reward students for their feces.

The toilet is designed to first deliver your excrement into a special underground tank, reducing water use, before microorganisms break the waste down into methane, a clean source of energy that can power the numerous appliances that dorm life requires.

“If we think out of the box, feces has precious value to make energy and manure,” Cho explained. “I have put this value into ecological circulation.”

The toilet can transform approximately a pound of solid human waste – roughly the average amount people poop per day – into some 50 liters of methane gas, said Cho. That’s about enough to generate half a kilowatt hour of electricity, enough to transport a student throughout campus for some of their school day.

Cho has even devised a special virtual currency for the BeeVi toilet called Ggool, or honey in Korean. Users of the toilet can expect to earn 10 Ggool per day, covering some of the many expenses students rack up on campus every day.

Students have given the new system glowing reviews, and don’t even mind discussing their bodily functions at lunchtime – even expressing their hopes to use their fecal credits to purchase books.
