The best part is the brief addendum about some of the bunny suit inhabitants of the chip fabs (~20 minute mark), and how they are weird, but that the gender distribution of their children is, in fact, "normal" or at last not specifically a product of their occupation.
Going out on a limb here, it's probably an air traffic adaptation, that arose due to a conflict in sharing air space with pollinating insects like bees, which have coincidentally adapted to notice UV reactive flowers.
For whatever reason, the UV reactive squirrels likely have survived more encounters with UV other sensitive flying animals (most likely, stinging insects) than the non-UV fluorescent variety, thus being selected for.
Hypothetically, if you're a UV reactive object, insects probably treat you differently.
A flying squirrel careening through tree canopy at break-neck speeds probably crashes into insect hives once in a blue moon. Some of those squirrels probably got stung to death, but maybe the UV squirrels registered in insect brains as falling plant matter (a big ass flower getting knocked off a branch incidentally), thus not a threat, thus no crisis, thus no fight or flight response, thus no swarming killer sting attacks.
Just an idea. No real evidence supplied. Google your own links.
Letting a stranger execute a stranger doesn't fit in with the basic concept of personal choice which affects only one's self or family members. In fact, it's in direct contravention to the underlying concept, so you're clearly lost at sea, and digressing.
