Well the text in the image of the "definition" of a square is clearly tailored to fit this joke, thats why the logic of what a square actually is doesn't apply. Its like telling Diogenes that his chicken is not technically a human because it doesn't have two hands and a nose.
We are like a CO2 bomb, there has never been so much put into the air in such a small time scale, what usually takes 1000s and millions of years we did in ~100 years.
That time was like 30 years ago. Now we can either stop using them altogether and have a bad time, or we can keep using them and have a slightly more bad time.
