There Are 8 Boundaries For a Safe Planet. To Be Fair, Earth Would Fail 7 of Them.

[Frank Robert]

A new report published in the Journal Nature Sustainability found that Earth has already crossed seven out of eight planetary boundaries, which are thresholds that define the safe operating space for humanity. The only boundary that has not yet been crossed is the one for chemical pollution.

The study, which was conducted by an international team of researchers, found that climate change, biosphere integrity, land-system change, freshwater use, and nitrogen and phosphorus cycles have all been pushed beyond safe limits. These changes are already having a negative impact on human health, food security, and the environment.

The eight planetary boundaries are:

• Climate change
• Biosphere integrity
• Land-system change
• Freshwater use
• Nitrogen and phosphorus cycles
• Ocean acidification
• Stratospheric ozone depletion
• Atmospheric aerosol loading

The researchers define a safe operating space as the range of conditions within which the Earth's systems can continue to function in a stable and predictable manner. When these boundaries are crossed, the Earth's systems become more vulnerable to shocks and stresses, which can lead to cascading effects and unpredictable outcomes.

The study found that Earth has already crossed seven of the eight planetary boundaries. The only boundary that has not yet been crossed is the one for chemical pollution. However, the researchers warn that this boundary is also under threat from human activity.

The study's findings are a sobering reminder of the challenges we face in protecting our planet. However, they also provide a roadmap for action. If we take the necessary steps now, we can still avoid the worst impacts of climate change and environmental degradation.

The wolf is surly come tonight to eat you up.
However, I can provide you a way out,
If you gave me 100 thousand dollars, I can make the wolf go other ways.

Sounds good enough? Your argument follows the same logic.

Not my argument. I am much more pessimistic. There is a lack of public acceptance and lack of political will. Add to that the pace of change and have likely already breached several tipping points such as the melting of the Arctic sea ice.

To my evaluation, none in the list can be called a “failed boundary”.
So the rest of the argument is invalid. It is not your argument, but you quoted it, and it seems you agreed with it.
Don’t fool yourself by this lie.

Hey, Juve!

Where you been!?

Took a course called “career preparation” in the largest university of the world.
Glad to see that you are still here.

You are entitled to your opinion.

So the rest of the argument is invalid. It is not your argument, but you quoted it, and it seems you agreed with it.

That I quoted an article for discussion does not make it my argument.

Don’t fool yourself by this lie.
