THE NINE PLANETARY BOUNDARIES

This stark warning comes after an Earth resilience strategist warned mankind has exceeded four of the nine limits for hospitable life on the planet.

Johan Rockstrom predicts we are getting close to dangerously close to hitting the fifth in a an article published in Science earlier this year.

Rockstrom came up with the idea of nine planetary boundaries in 2007 and his theory goes that in order to keep Earth hospitable, humans need to live within these nine specific boundaries.

THE NINE PLANETARY BOUNDARIES:

1. Climate change

2. Lost biodiversity as species become extinct

3. Addition of phosphorus nitrogen and other elements to the world’s crops and ecosystems

4. Deforestation and other land use changes

5. Emission of aerosols into the atmosphere that affect climate and living organisms

6. Stratospheric ozone depletion

7. Ocean acidification

8. Freshwater use

9. Dumping of organic pollutants, radioactive materials, nanomaterials, micro-plastics and other man-made substances into the world’s environment.

SO FAR, WE’VE WRECKED FOUR OF THEM:

As the above graphic shows, when it comes to harming the planet, humans have already made massive mistakes when it comes to climate change, extinction of various species and adding

phosphorus and nitrogen to the world’s ecosystems.

We’ve also made mistakes when it comes to deforestation and are on the way to ruining the Earth further in regards to poisonous aerosol emissions and stratospheric ozone depletion.

However Rockstrom maintains his recent paper — which is co-authored by 17 colleagues — isn’t a doomsday message, but more of a reminder how lucky humans have been to survive this long.

The planet has been our best friend by buffering our actions and showing its resilience,” Rockstrom told Ideas Ted, earlier this month.

“But for the first time ever, we might shift the planet from friend to foe.”

  1. Unbelievable. I’m sure we’ll surpass the next 3 or 4 within 15 years. I’m only sorry for the damage we’ve done to the other inhabitants of the world. As humans, we deserve whatever we get, but they don’t.
