Anatole tries to get Leah to understand that things just aren't fair. Give it a few decades: she's going to realize the truth of this firsthand.

This interaction helps Leah transition from believing that God has the good of mankind at heart, to blaming Him for all the world's troubles, to maybe not believing in Him at all. Talk about a character arc.

Anatole takes an attitude similar to Adah here: even ants have to eat. And as we see later, the humans are like the ants when they do their hunt. They burn the ground, trap the animals, and strip them of their flesh.
