can it kill Tardigrades though?
I'm pretty sure nothing can kill tardigrades.
I could see UV light also causing plastics to oxidize and become brittle much faster, because they might not be made for that kind of exposure. So using UV light might mean having to replace a lot of plastic things too.
Exactly, yes! Pretty much everything when left out in direct sunlight eventually fades or breaks down. There's a reason why UV light kills germs, it damages what is touches.
Shadows.
You really dont want to live in a sterile environment, you actually need some stimulation to your immune and other bodily systems. Most body stuff is like muscles including the immune system - when you regularly over load and stress them, thats the impulse to stimulate growth and evolving.
