The o-zone keeps
ultra-violet radiation from reaching the surface of the earth. Ultra-violet rays come from the sun. They will cause twelve million estimated people to get
life threatening forms of skin cancer over the next fifty years. Only five hundred thousand were expected to be at risk. A dangerous amount of UV rays will also lead to
cataracts. If they are not removed, the result will
be blindness. Argentina is suffering because of the
depletion of the o-zone. It is causing plants (used
for food) to become uneatable and causing some sheep to become blind. UV rays will also weaken our immune system, which
helps your body fight off diseases.
How can we protect
You should always wear protective
clothing and sunscreen when you are going to be in the sun for long periods of time.
