Our species evolved for hundreds of thousands of years in Africa, spending most of our lives under direct sunlight. At times, there was much more UV radiation reaching Earth than today (magnetic field fluctuations, changes in solar activity...)
Nowadays, air is full of garbage ranging from agricultural chemicals to nanoparticles from car/plane/ship exhausts, and many things inbetwen. All that s**t ends up on our skin, and gets absorbed.
Add to that the fact that most people who often sunbathe also often swim outdoors, and the fact that our waters are much more poluted than our air, and skin cancer almost seems surprisingly rare.
UV radiation probably have an effect, but it is more like a catalyst than cause of skin cancer. Which makes it great scapegoat, so we don't have to admit we fked up Earth so bad it is already pretty much unhabitable.
