Years of abuse and misuse of the Earth’s forests have resulted in the tropics now emitting more carbon than oxygen, says a new study. This is alarming because tropical forests have always been considered a vital carbon “sink” that consumes carbon from the atmosphere and turns and releases it into oxygen. Today, however, tropical forests already emit almost twice as much carbon as they consume. Scientists say stopping deforestation and degradation in the tropics could help reverse this trend.
In a paper published in the journal Science, scientists from Boston University and the Woods Hole Research Center said there is a limited window of opportunity to reverse the troublesome trend, and that’s by restoring forested areas.
The researchers used a new method to assess carbon density in areas affected by deforestation and degradation.
Dr Wayne Walker, a member of the research team, said:
“It can be a challenge to map the forests that have been completely lost. However, it’s even more difficult to measure small and more subtle losses of a forest. In many cases, throughout the tropics, you have selective logging, or smallholder farmers removing individual trees for fuelwood. These losses can be relatively small in any one place, but added up across large areas they become considerable.”
The researchers found that the tropics now release more carbon than they take in.
While 862 teragrams of carbon are emitted, only 437 teragrams are consumed.
Dr. Alessandro Baccini, who led the study, was quoted as saying:
“These findings provide the world with a wake-up call on forests. If we’re to keep global temperatures from rising to dangerous levels, we need to drastically reduce emissions and greatly increase forests’ ability to absorb and store carbon. Forests are the only carbon capture and storage ‘technology’ we have in our grasp that is safe, proven, inexpensive, immediately available at scale, and capable of providing beneficial ripple effects—from regulating rainfall patterns to providing livelihoods to indigenous communities.”
More than 60 percent of carbon emissions in the tropics comes from Latin America
Meanwhile, 24 percent comes from Africa and 16 percent from Asia.
The study comes as a reminder for individuals and organizations to work together and do their part in preserving our forests.
Scientists Restore Consciousness in a Man Who Spent 15 Years in a Vegetative State
This breakthrough challenges the belief that disorders of consciousness lasting more than a year are irreversible.
Scientists at the French National Center for Scientific Research have made a major breakthrough in the study of consciousness disorders. A 35-year-old man who had been in a vegetative state for 15 years after a car accident has shown signs of consciousness after neurosurgeons implanted a vagus nerve stimulator into his chest. The man is still a long way from full wakefulness, but his case challenges the belief that disorders of consciousness persisting for more than a year are irreversible.
The vagus nerve connects the brain to the gut and other parts of the body. Stimulation of this nerve has been shown to benefit people suffering from depression or epilepsy and to help in the process of waking up and staying alert. Angela Sirigu of Institut des Sciences Cognitives Marc Jeannerod in Lyon, France, co-author of the study titled "Restoring consciousness with vagus nerve stimulation," wondered if the vagus nerve can help restore consciousness to patients with unresponsive wakefulness syndrome.
Sirigu and the rest of the research team wanted to pick a difficult case to test the theory.
ADHD Is A Complete Hoax, Claims Renowned Harvard Psychologist
According to Harvard professor and acclaimed psychologist Jerome Kagan, “ADHD isn’t real. “
Aside from teaching at one of the most respected universities in the world, Jerome Kagan has likewise made a name for himself in the field of psychology. In fact, he has been listed at #22 among the most eminent psychologists of the 20th century, putting him a rank higher than Carl Jung, famed Swiss psychiatrist and psychoanalyst, who is at #23.
With his impressive background in mind, we can all assume he knows what he's talking about when he says something. Recently, he did come up with a pretty bold claim saying ADHD is not a real condition.
According to Harvard professor and psychologist Jerome Kagan, ADHD is a big hoax.
Lab-Grown Leather Might Just Be the Next Big Thing in Fashion
The fashion staple is getting an upgrade.
When you talk about fashion staples, a trusty leather jacket is always on top of the list. It's a style classic and a flexible piece of clothing. While some may still prefer genuine leather when filling up their closets, the movement to a more responsible consumer culture has encouraged even the pickiest shopaholics to go for alternatives to genuine leather.
And soon, a new, science-backed option could become available to all. A New York-based company is saying bye to the cow and hello to the lab as they create lab-grown leather.
Modern Meadow is a biofabrication company that grows animal-free leather made from living cells.
