I read the articule two weeks ago. It is from my social environmental analysis´s class and the articule is about of 9 planetary boundaries which are limits what we passed for the pollution of the Earth.
It´s a general view how we are today. The actors explain each of the limits and propose new methods of quantifying.

Here are de articule if you like to read.

And this is a new vocabulary from the articule, which I didn't understand when I was read.

Finally this is the test link, to be able to continue with the new words that I get to upload.  https://quizlet.com/_361c05
