I was surprised to hear that around 2000 people die every year because of skin cancer. I haven’t known about skin cancer well, but I understand it’s too serious now. I didn’t know we can make Ozone! If we can make it easily and safely, we see a ray of hope with our future.
In Japan almost all people have white skin, but in Australia almost all people have black skin. I thought that there are related to Ozone. I am afraid of UV, because it cannot be seen, although it caused a terrible illness.
