Yeah this is what frustrates me when people complain about illegal immigration. Those places are now experiencing food shortages and will just get worse. Where do you think people will go when there is no food in their own country. Do you think they will just let their children starve? Do you really think a physical wall will stop them from trying to feed their children?

Generational-wise, we are having less children then the previous. That’s the point of the comic.

No, climate change was not a concern for them back then.
