Ozone

=__//**The Ozone**//__= Ozone is a molecule built from three atoms of Oxygen its sign is (O 3 ). Ozone is a toxic gas which can cause breathing difficulties. The Ozone gas is in the earth statosphere which create the Ozone layer, the Ozone has an important job to help us live, The Ozone prevents damages that causes the ultraviolet light from reaching the earth's surface.

When we use products that make the ozone attack their chimical materials. Whenever the Ozone is attacking those materials, it starts to crack. __What can we do:__ The ozone is a poisonous gas which is a form of oxygen. There are two type of ozone's, good ozone and bad ozone. Until now a part of the good ozone layer is gone. It is gone thanks to the human being- we destroy it by making chemicals. It isn't a good situation because without enough good ozone people won't get\may not get enough ultraviolet radiation. It may increase the risk of skin cancer and immune system problems.(those are just two examples of the problems it will cause). "Bad" ozone refers to ground level. It forms when pollutants from factories, motor vehicles or other sources that react chemically with the sunlight. It is dangerous to us because breathing bad ozone can be harmful, causing breathing problems such as: coughing, asthma and lung damage, just if you are regularly exposed to it.
 * //__The Ozone's cracking__//**
 * //__Things can make the Ozone crack:__//**
 * Chemical gases from cars
 * Preon gas from air conditioner refrigerators, some sprays of deodorant and perfumes.
 * Farts.
 * Not use the spray deodorants.
 * On the near future, a new kind of cars are going to be used more, cars that work by using electricity or solar energy, we can use them more.
 * Recycle.

Have you heard about the "Ozone hole" ?  In 1980, reported the British meteorological measurement station, which is located on the mainland Antarctica (South Pole of the Earth ), the sharp drop in the stratosphere ozone concentration. Satellite images taken over the South Pole, proved indeed destroyed the ozone layer.

That smell is very, very **healthy** because the ozone is built from 3 molecules of oxygen and the air includes 2 molecule of oxygen. Which means - by a simple math, for instance: If you breath two ambitions of the ozone, it's like you breath three times a normal air.
 * __For your general knowledge:__** Did you know that the smell of the ground after a rainy day, is the smell of the ozone?
