PLZHELP!!! how are humans impacting the ozone layer???

Question

and also, any links to websites that have information on how humans are impacting the ozone layer??

Answer 1

Comparison of CO2 emissions from volcanoes vs. human activities.
Scientists have calculated that volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1999, 1992). This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 22 billion tonnes per year (24 billion tons) [ ( Marland, et al., 1998)
(sorry this portion does't answer your question directly, but i like to get it in whenver anythign referring to global warming is mentioned, just to get rid of the old myth that volcanoes produce more CO2)

Answer 2

Studies that try to implicate humans as culprits in changes of the ozone layer, are political in nature. As yet I have not seen any proof that man can change enviromental factors on earth. Many of the global warming advocates ignore the fact that the sun is going through a cycle now where it is putting out more heat. Because this assertion (global warming) is not based on science, but a political agenda.

Answer 3

Hi. CO2 does not effect the ozone. It retains heat. Human activity by way of ozone depleting chemicals has reduced the ozone layer, but recently the ozone hole over Antarctica has grown smaller, a hopeful sign.

Answer 4

humans use many chemicals which can deteriorate ozone layer.

Still many developing countries use chloroflorocarbon gas in refregerators (cheap to manufacture), but it had a profound effect on reducing the ozone layer through chemical interaction. Once known, it has now been banned on many developed countries.

Answer 5

a large hole has developed over the Antarctic.But it is closing up slightly over the years since they outlawed those fluorocarbons.we must stay aware and stop any more pollutants effecting the ozone layer. as it is for our basic need and right for survival to keep it healthy.
Peace.

Answer 6

supposedly we are, by releasing flourocarbons into the atmosphere. but i'm not convinced. it seems to fluctuate on its own. i suspect that it is a natural phenomenon that we have only recently been able to detect and measure.
