Scientists Warn Humans Are Pushing Earth Outside 'Safe Operating Space'

Scientists Warn Humans Are, Pushing Earth Outside , 'Safe Operating Space'.

According to scientists, several key indicators of planetary health show that human actions have pushed Earth into a danger zone.

29 scientists from eight countries analyzed "planetary boundaries," which ensure a stable and livable Earth.

CNN reports that the scientists warned that humans threaten to trigger dramatic changes in Earth's climate.

The "planetary boundaries" researchers looked at include biodiversity, freshwater use and the impact of synthetic chemicals.

According to the report, published in the journal 'Science Advances,' human actions have breached six of these thresholds, pushing the Earth outside "safe operating space.".

On the bright side, the ozone layer is on track to recover completely, thanks to international efforts to limit the use of ozone-depleting chemicals.

According to Simon Lewis, a professor of global change science at University College London in the U.K., the report comes as, "a strikingly gloomy update on an already alarming picture.".

Humans are destroying biodiversity, changing the climate and polluting our home to such an extent that we’ve pushed our planet out of the stable conditions that enabled human civilizations to emerge, Simon Lewis, professor of global change science at University College London in the U.K., via CNN.

It couldn’t be a more stark warning, Simon Lewis, professor of global change science at University College London in the U.K., via CNN.

According to Andrew Fanning, a visiting research fellow at the University of Leeds in the U.K., the report provides "strong evidence-based support" for taking action.

'Newsweek' reports that neuroscientists have discovered a link between an individual's dietary choices and specific brain activity patterns. According to scientists at Queen's University at Kingston, connections exist between body mass index (BMI) and certain brain states necessary to achieve goals. . The team looked at data from three MRI studies involving 123 participants making food choices under a number of different conditions.

Scientists compared the brain activity patterns from when participants chose food they normally eat, versus when they were instructed to focus on healthy foods.

Scientists compared the brain activity patterns from when participants chose food they normally eat, versus when they were instructed to focus on healthy foods. 'Newsweek' reports that the results offer insight into how variables are integrated by the brain and how that impacts dietary control. The findings suggest that the number of large-scale brain pattern reconfigurations necessary to influence behavior may determine if people struggle to maintain dietary control. .
