OZONE

 We are exposing us to harmful Ultraviolet rays light, that’s why ozone layer destruction is serious problem. Ozone layer is the layer of the upper atmosphere where most ozone layer is concentrated. It can protect living things and block out harmful UV rays.

 These days, the ozone layer is slowly weakened, because we use amount of air conditioner and refrigerator. Even we use Freon gas with spray.

 If our eyes or skin exposed to UV rays, we can cause skin cancer or cataract. Even it can decrease the rice crop and fish can’t live in sea. We should use LPC gas or another source of energy such as natural gas. And then we should reduce spray and using air conditioner.

 If you go somewhere that is short distance, you should walk or get on public transportation. If you want to work out, you can ride bicycle. We should try not to waste anything.
