The man-made gases of CFCs (chlorofluorocarbons). Chlorines and bromines from these gases stay in the atmosphere for years, destroying ozone molecules. This allows the sun's dangerous ultra violet (UV) radiation to reach earth, causing human cancers and damage to crops.
CFC's are one threat to ozone. Greenhouse gases are other.
The threats to ozone layer include the CFC chemicals produced by man. They react with ozone to decompose it.
Hazards to ozone are many. CFC being one of it.
The ozone protects from hazards. It is a layer in stratosphere.
There is not actually a hole in the ozone layer. The ozone has been reduced below some limit.
Hazards are a common in ozone. CFC's keep destroying ozone.
Some elements are blamed for ozone layer. These are CFC's.
See "What does the ozone layer do?"
Health Hazards result from a thin ozone layer. There are skin cancer, eye cataract etc.
The ozone layer is spread throughout. However some countries have a ozone hole in it.
The ozone protects from hazards. It is a layer in stratosphere.
The ozone is harmful not at stratosphere. It is harmful at some layer. Te layer is troposphere.
There is not actually a hole in the ozone layer. The ozone has been reduced below some limit.
The ozone layer is present in the stratosphere region of the atmosphere. It is important as it protects us from the harmful UV radiations of the sun that cause several health hazards including skin cancer!
Hazards are a common in ozone. CFC's keep destroying ozone.
Ozone layer is created by natural processes. UV and thunder are some of them.
Some elements are blamed for ozone layer. These are CFC's.
See "What does the ozone layer do?"
If the ozone layer is destroyed, harsh consequences will follow. There will be no life.
The release of CFC's lead to ozone layer depletion. It reacts with ozone to deplete it.
