The ozone hole!!!

For nearly a billion years, ozone molecules in the atmosphere have protected life on Earth from the effects of ultraviolet rays. The Antarctic ozone hole was discovered in 1985 by British scientists Joesph Farman, Brian Gardiner, and Jonathan Shanklin of the British Antarctic Survey. The ozone hole has got about 27 million km. Freon destroys the ozone. Freon is in deodorants but now in many deodorant aren't freon because firms which are product deodorants want to protect Earth from the ozone hole. When ozone press away we will attacked for UV. We must protect ozone because when UV tear to troposphere we die. Fabrics destroy ozone. They can put special filter on smoke-stack.
