Spray nets contain CFC's. They react with ozone and deplete it.
The ozone is harmful not at stratosphere. It is harmful at some layer. Te layer is troposphere.
Ozone layer cannot be harmful. It protects us from harmful UV rays of the sun.
Halons are harmful for ozone. They also react with ozone to deplete it.
Ozone layer protects us from harmful UV rays. these are harmful UV radiations of the sun.
See "What is causing the depletion of the ozone layer?"
CFCs harm the ozone layer by breaking down ozone molecules in the stratosphere, specifically in the layer known as the ozone layer. This depletion of ozone molecules can lead to an increase in harmful ultraviolet radiation reaching the Earth's surface.
The ozone layer is most harmful in the stratosphere, the second layer of the atmosphere. It helps to protect Earth by absorbing harmful ultraviolet radiation from the sun, but ground-level ozone can be harmful to human health as a pollutant in the troposphere.
The ozone layer, which is found in the stratosphere, screens out harmful ultraviolet (UV) radiation from the sun. UV radiation is dangerous to living organisms as it can cause skin cancer and damage DNA.
Sun rays that are harmful are protected by the ozone layer. This layer is a boon to the organisms of the earth.
Ozone is found in the ozone layer. It protects us from the harmful UV rays of the sun.
It is harmful at ozone layer. It is because this leads to depletion of ozone.
CFC's are harmful. They form a chain reaction in ozone layer to destroy it.
