CAUSES OF THE OZONE HOLE

The causes of the ozone hole The substances most responsible are the so-called CFCs (chlorofluorocarbons), gases widespread in spray cans or in the refrigeration circuits

WHAT IS THE OZONE HOLE

The ozone hole consists of the reduction in the thickness of the ozone layer in the Earth's atmosphere, the band that protects us from ultraviolet rays.

WHAT IS THE OZONE HOLE

The ozone hole consists of the reduction in the thickness of the ozone layer in the Earth's atmosphere, the band that protects us from ultraviolet rays.

THE OZONE HOLE

The ozone layer is a fundamental shield for the interception of radiation that is lethal for life on Earth, and its formation occurs mainly in the stratosphere at the most irradiated tropical latitudes, while global circulation then tends to accumulate it more at high latitudes and at the poles .

OZONE HOLE RISCK

The ozone hole can have deleterious effects on all life of microorganisms, animals and plants; in particular, radiation not filtered by the ozone layer can affect the life of human cells, creating melanomas on the epidermis and skin tumors, breaking the chain of the genetic code
