How harmful is the radiation from the sun?

Why is the sun bad for us?
The sun radiates light to the earth, and part of that light consists of invisible UV rays. When these rays reach the skin, they cause tanning, burning, and other skin damage. UVA rays cause skin aging and wrinkling and contribute to skin cancer, such as melanoma (the most dangerous form of skin cancer).
Do we really need sun protection?
