How the sun can be harmful?

Question

As we all know the sun is a great thing but it does cause some serious problems and some people are becoming more concerned with the dangers of over-exposure to it.

My question is that what is the source of the problem,

the extent and effects of the problems,

and solutions to the problem(any brainstorming) (this includes changes to people's lifestyles,i,e, behaviour, clothing, equipment, and new products that may help)

thanks
