Earth is beyond six out of nine planetary boundaries

Question

I have just found out about the articles that scientist have recently published, talking about some planetary boundaries that we have crossed.

I wasn’t really able to get the full hang of it, but I’d really like to understand the concept of these boundaries and what they are, since there are only 3 left and 2 years ago we were crossing the fourth one and now we’re passed the 6th one, and according to news it could potentially cause societal collapse.

So, what are these boundaries and what happens if we cross all 9? How do they affect our society?

Edit:
The article I am on about is found [here](https://www.science.org/doi/10.1126/sciadv.adh2458)
