UV radiation has many different effects on us.
If the UV radiation lowers, it will make it colder, and will lower our production of vitamin D.
if the UV radiation increases, the chances of skin cancer, sunburns and sun burning on the whites of your eyes will start to occur, and it will get much more intense.
Too intense for sunscreen to protect our skin fully from the effects of radiation.
It will also cause people to wrinkle faster and seems to make us age faster.
This will not happen if we have less UV radiation, but we will lose the production of most of our Vitamin D from the sun.
