"No words".
Except in the bottom of the picture, because it still thinks we are not able to understand the message of the picture without someone saying "THERE IS A MESSAGE, DUDE".
Even if that's true, there are way more people breathing the oxygen now than there were a hundred years ago, not to mention the space they (humans)take up
As to the space - I saw a report (or research paper or whatever it was) recently that said we have enough space just here in America for everyone on the planet. It did not mean shoulder to shoulder, it said in houses but I don't remember how many to a family or how big the yard would be. Some areas are crowded, some are still wide open. As a whole, we will be OK.
