Air Contamination


Pollution-damaged air, environment, water, human beings, for that we must be aware of the problem.
Another strong cause of air contamination is the operation of the factories that contaminate a lot and no one make a control about this process of the factories.
Ozone is one of the top layer of the earth, and helps filter
ultraviolet rays from the sun, but if you are at ground level
becomes a very powerful cleaner.
To have cleaner air, it is need to help improve our
environment, nature is all and in our hands to keep it to
bequeath to our children a healthy environment.
