Paul reacted after witnessing living colony for shrunken people not protected against insects and birds:
Paul: What, and there's no net? No walls?
Jorgen: No, we've been lucky. We are too close to the sea for the mosquitoes. And over the years we realized that the birds, they prefer the lemmings.
What does it mean, "for the mosquitoes"?
I find this line from Downsizing 2018 movie.
