Ozone is made both by Nature (ozone layer, lightning, waterfalls, and as an oxidant produced to fight infection), by Man (oxidant used for many industrial, and commercial uses), and by both together (ozone pollution).
Chlorofluorocarbons (CFCs), halons, and some types of hydrochlorofluorocarbons (HCFCs) are manmade substances that can break down ozone in the Earth's stratosphere. These chemicals release chlorine and bromine atoms when they reach the stratosphere, which then catalyze the breakdown of ozone molecules.
No, fire works donot harm ozone layer.The substances that are causing ozone layer depletion are freons, CFC's etc.. These are called as ozone-depleting substances (ODS).
Dacron is a manmade synthetic fiber, which is a type of polyester. It is not a natural fiber like cotton, wool, or silk. Dacron is known for its durability and resistance to wrinkles and stretching.
Chlorofluorocarbons (CFCs) are manmade chemicals that harm the earth's protective ozone layer by breaking down ozone molecules. This leads to the formation of ozone holes, which allow harmful ultraviolet radiation to reach the Earth's surface. Efforts have been made to reduce the production and use of CFCs through international agreements like the Montreal Protocol.

Zero. Rubber samples (natural and manmade) are aged at accelerated rates, by exposing them to elevated ozone levels, temperature, and humidity.
CFC's harm the ozone. They react with it and deplete it.

we are all natural because we weren't made in a factory we were made natural.Things that are made in factorys are manmade we are not manmade we are natural. Katrina LaChance- Bermuda138
The ozone in the ozone hole is very large in quantity. It cannot be replenished artificially.

NO it is natural!
