We thinned it.
Humans produce CFC's. These CFC's react with ozone to deplete it.
Ozone layer is affected by : 1. Human activities 2. Release of CFC gases.
The release of CFC's lead to ozone layer depletion. It reacts with ozone to deplete it.
See "Does the hole in the ozone layer effect human health?"
No, the ozone layer is not completely depleted, but it has been damaged by human activities such as the use of certain chemicals.
Some gaseous products of human activity can reduce the about of ozone in the upper atmosphere, thus decreasing the effectiveness of the ozone layer in shielding the surface of the planet from ultraviolet radiation.
Human activities that damage the ozone layer include the release of substances such as chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances. These chemicals are commonly found in refrigerants, aerosol cans, and foam products. When released into the atmosphere, they break down ozone molecules, leading to the thinning of the ozone layer.
Ozone affect human as it forms a layer of ozone molecules in atmosphere. The molecules absorb the UV rays protecting the humans.
The hole in the ozone layer is primarily caused by human activities releasing chemicals called chlorofluorocarbons (CFCs) into the atmosphere. These CFCs break down ozone molecules, leading to the thinning of the ozone layer.
Cow emissions, such as methane, can contribute to ozone depletion indirectly by influencing the levels of ozone-depleting substances like chlorine in the atmosphere. However, the impact of cow emissions on ozone depletion is relatively small compared to other human activities like industrial and transportation emissions.
Yes, chlorofluorocarbons (CFCs) have a negative effect on the ozone layer. When CFCs are released into the atmosphere, they break down and release chlorine, which can destroy ozone molecules. This depletion of the ozone layer can result in increased levels of ultraviolet (UV) radiation reaching the Earth's surface, leading to harmful effects on human health and the environment.
Ozone layer is present in stratosphere. It does not cause it any effect.
