How about the multitude of life on the planet that relies on photosynthesis?
And our own bodies? We get most of our vitamin D from a biosynthesis pathway that requires UVB exposure. Systematically depriving all of humanity of vitamin D could be disastrous.
And our circadian rhythms? The human circadian rhythm is mediated by two processes, denoted "S" and "C", of which C has evolved to rely on daily exposure to sunlight. The circadian rhythm affects almost all parts of our humanity.
