Become a sea turtle, humans don't live 200 years. And sea turtles have protective covering from UV-B radiation and can live under the sea. Both Mankind and his food sources require an ozone layer to survive. So we must concentrate on not screwing things up more than we already have, and even on reversing the damage (whether or not we caused all the damage). Arguments about ultimate responsibility are a waste of time and energy.
No, HAARP (High-Frequency Active Auroral Research Program) is not responsible for the holes in the ozone layer. The depletion of the ozone layer is primarily caused by human activities releasing chemicals like chlorofluorocarbons (CFCs) into the atmosphere. These chemicals break down ozone molecules, leading to thinning of the ozone layer.
Scientists believe that the thinning of the ozone layer since the 1970s is primarily human-induced, caused by the release of ozone-depleting substances into the atmosphere. These substances, such as chlorofluorocarbons (CFCs), have been shown to break down ozone molecules. Efforts to reduce the use of these substances have led to a gradual recovery of the ozone layer in recent years.
Yes, there is a hole in the ozone layer. The ozone layer is a region of the Earth's stratosphere that contains a high concentration of ozone molecules. This layer helps protect the Earth from harmful ultraviolet radiation from the sun. However, human activities, such as the release of certain chemicals like chlorofluorocarbons (CFCs), have caused a thinning of the ozone layer, leading to the formation of a hole primarily over Antarctica. Efforts have been made to reduce the use of ozone-depleting substances and the size of the hole has been decreasing in recent years.
There is evidence that large portions of the ozone layer have disappeared a few times in the past, even back before Mankind or the Industrial Revolution. So there is no way to know when was "first". Thankfully, the Sun rapidly restores some ozone gradually. The ozone layer has always become thinner during each poles winter months due to a lack of sunlight. No thinning occurs over populated areas. This is reserves to only areas that have long periods of darkness, like out poles during their winters.
The ozone layer after 5 years is dependent on us. It depends how we use CFC's.
Ozone layer was depleted. It's size has been coming to normal in recent years.
The thinning of the ozone layer occurs over each pole during the winter months at that pole. Countries very near the South pole could experience some reduction of their ozone during the winter months during years with unusually high solar activity. See the related questions section below.
The ozone layer protects us form the Sun's harmful ultraviolent rays. If we didn't have the ozone layer, we'd all get really sunburned without sunscreen and we would have a higher chance of getting skin cancer. Destruction of the ozone layer in parts of the world are caused by CFC chemicals that are realeased into the air. When they reach the ozone layer over about 30 years, they destroy part of the ozone layer, leaving a hole in the ozone. There is one located in Austrailia, and the percentage of skin cancer of cases have risen. CFC production has been reduced and parts of the ozone holes have been replaced by new ozone.
The stratospheric ozone layer is the layer that protects the earth from UV radiation which is harmful to all life forms. Over the years pollution and other things have cause destruction to the ozone layer and began to break it down and deplete it's ability to protect the planet. Eventually, if this continues, the ozone layer will disappear and UV rays will destroy the earth.
The size of the ozone layer has changed. Due to the CFC's the ozone has decreased. Most of the loss has been over the poles.
The ozone layer has been decreased over the years. It is because of use of CFC's.
If CFC's cannot be used the ozone level will grow again in the next 60 - 120 years
