    I think it is cabin fever! Go outside for five minutes and breath the clean air...because come Holloween the time changes. It is good to disagree and it is good to shut up sometimes to keep the peace. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_m_32.gif[/img]

    has anyone of you heard of a good scientific paper containing:

    what kind of sientist publishes that?
    is the textbook a religious one? or do you go to a religious school?
    sure, I've seen scientific textbooks talking about religion, but not HAVING one.
    about the chlorine....

CFCs are very stable chemicals that do not break down in the lower atmosphere. When released, they drift up into the stratosphere where they are broken down by ultraviolet radiation. This again releases the chlorine that destroys ozone. A single atom of chlorine can destroy 100,000 or more molecules of ozone.Measurements show that the increase in stratospheric chlorine since 1985 matches the amount of CFCs and other ozone- depleting substances released by human activities.

    now... ok, that site also says that the ozone hole doesn't cause global warming. ok I was wrong. you CAN change MY mind with facts.

    Very strong greenhouse gas.
    Residence time 60-100 years.
    .....Surface ozone is produced as an artificial by-product of photochemical smog, and is hazardous to human health.

    Important in the greenhouse effect and causes nitrogen loading.
    Human inputs 6 million tons per year, and 19 million tons per year by nature.
    Residence time in the atmosphere about 170 years.
    1700 (285 parts per billion), 1990 (310 parts per billion), 2030 (340 parts per billion).
    Comes from nitrogen based fertilizers, deforestation, and biomass burning.

    less respect for your textbook. They hide facts from you. it's not just one thing. sure, maybe nature releases chlorine into the air, but it's dissolved in rain and it never reaches the stratosphere.
    sure, CO2 is released by all organisms and the addition rate of humans isn't that big compared to nature, BUT humans are not only adding CO2, but PREVENGING it being converted into O2!! and sure, wildfires are natural (and essential to many habitats), but when humans came, we messed up everything and it's BECAUSE OF US that there are more, harsher wildfires.
    so by adding all that, the CO2 level rising is NOT because of nature but because of human activities.
    and it's not just one gas. it's MANY gases we release that contribute to global warming. and MANY things we do. you cannot just hide facts about some things and completely ignore the rest of the things.
    and there are more facts. I recomend you go and read them becuse I don't want to be posting so much (too late eh?)

    you can't do that in many places... because of humans!

    this is not just something to be taken lightly.

    I compltely disagree.
    An ozone hole means that the powerful ultraviolet rays to get through.
    The result:

    Antarctica is slowly compltely melting away.
    Many more chunks of ice are breaking off and as these too melt, the worlds oceans are slowly rising.
    It also means destruction of habitats for animals int he arctis region such as penguins.

A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. There is so much oxygen in our atmosphere, that these high-energy ultraviolet rays are completely absorbed in the stratosphere.
    and when you ADD oxygen-depleting chemicals AND kill photosynthetic organisms, you have things taking out O3 WHILE other thigns are preventing the formation of O3!!!
    that's from: http://earthobservatory.nasa.gov/Lib...e/ozone_2.html
    as are these:

As long as water is poured into the bucket at the same rate that water is leaking out, the amount or level of water in the bucket will remain the same. Likewise, as long as ozone is being created at the same rate that it is being destroyed, the total amount of ozone will remain the same.
    BIG picture!!!

Human production of chlorine-containing chemicals such as chlorofluorocarbons (CFCs) has added an additional factor that destroys ozone. CFCs are compounds made up of chlorine, fluorine and carbon bound together. Because they are extremely stable molecules, CFCs do not react easily with other chemicals in the lower atmosphere. One of the few forces that can break up CFC molecules is ultraviolet radiation. In the lower atmosphere, CFCs are protected from ultraviolet radiation by the ozone layer itself. CFC molecules thus are able to migrate intact up into the stratosphere. Although the CFC molecules are heavier than air, the air currents and mixing processes of the atmosphere carry them into the stratosphere.

    Yea, I'm sorta late coming into this, and truthfully I heven't read the topic.

    There are plenty of them out there, you just wouldn't agree with them, because that is not what you believe, just like "religious" people don't agree with what you do or don't believe(I personally don't really care either which way).

    About the Ozone Hole:
    It is not much of a worry, it fluctautes from year to year, and yes the majority of the gasses that deplete it, don't even reach it. The more important issue is actually water polltuion. You hear of more instances(at least I do) of water poisoning than you do of air poisoning/skin cancer. I'll add more if needed, right now, I gotta get some school work done.
