The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists.

The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is necessary to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light.

However, manufacturing and household chemicals that are currently in use have been found to destroy ozone, and the problem has worsened to an ozone layer "hole" above Antarctica.

Ozone levels there are 40 percent below normal, and there may be another ozone hole forming above the Arctic region. This property lets ozone block out ultraviolet rays and makes it an essential part of the eco-system.

When harmful ultraviolet-B rays wavelength NM come through the atmosphere, the O3 molecules absorb the energy and one oxygen atom removes from the molecule.

The stray atom will eventually collide with another O2 molecule and ozone will be reformed. With this process, the level of ozone remains constant, as it has for millions of years. It is difficult to ban them outright because they have hundreds of industrial uses. The molecule comes apart and a majority of the chlorine then forms hydrogen chloride or chlorine nitrate, which then decay into atomic chlorine or chlorine monoxide.

As they come in contact with an ozone molecule, they cause the third oxygen atom to detach and form an O2 molecule with another lost oxygen atom. All ozone-destroying compounds contain at least one of two common elements: Compared atom-to-atom, bromine can destroy times the number of ozone molecules as chlorine.

Fortunately, its atmospheric concentration is much smaller. Humans, animals, marine life, and plants are all susceptible to UV radiation damage.

Current studies indicate that ultraviolet rays could be disastrous to the marine eco-system. High UV concentration causes phytoplankton, microscopic organisms at the base of the food chain, to decrease their reproductive activity. Although there is no serious widespread effect now, the problem may escalate in future years.

Ozone Depletion - Essay

Of the three types of skin cancer, basal.Ozone layer is a deep layer in earth’s atmosphere that contain ozone which is a naturally occurring molecule containing three oxygen atoms. These ozone molecules form a gaseous layer in the Earth’s upper atmosphere called stratosphere.

This lower region of stratosphere containing relatively higher concentration of ozone is called Ozonosphere. Ozone Depletion Atmospheric ozone layer depletion is a serious problem currently facing the world.

The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone hole over Antarctica, and now a thinning of the ozone layer above the Arctic, has led to worldwide action to curtail the use of the primary culprits: CFCs and related compounds called.

The deterioration of the ozone layer, caused by Cfcs, endangers the lives of humans'. Cfcs have a diminishing effect on the ozone layer.

In December of , Rowland and Molina discovered that CFCs can destroy the ozone in the stratosphere. In June , the Natural Resources Defence Council (NRDC) sued the Consumers Product Safety Commission for a band of CFCs used in aerosol spray cans. would react with the ozone and convert it back into plain oxygen. The even worse part of all this is that these chlorine molecules do not become inactive after the first reaction with the ozone and would be available to destroy more ozone molecules. The deterioration of the ozone layer, caused by Cfcs, endangers the lives of humans'. Cfcs have a diminishing effect on the ozone layer. Furthermore, the deterioration of the ozone cause an increase of Ultraviolet (UV) radiation which can have a negative effect on human skin and eyes/5(5).
