Is the greenhouse effect the same as ozone depletion?
No, they are different. Ozone depletion results in more ultraviolet (short wave) radiation reaching earth's surface. The greenhouse effect results in more infrared (long wave) radiation being absorbed by the atmosphere.
Controversies such as those surrounding global warming and ozone depletion involve long-term prediction and therefore are undecidable in the short term?
Yes they are long term. They cannot be predicted for short term.
What are phytoplankton and how are they affected by ozone depletion?
UV-B passes to Earth's surface, when ozone does not stop it. UV-B can travel some short distance into seawater before it is scattered and its energy reduced. Phytoplankton has DNA, and lives near the surface of the ocean where sunlight is strong. UV-B destroys DNA.So ozone depletion kills or mutates phytoplankton, via UV-B from the Sun.
Why is the ozone hole only there for a short time?
The ozone hole is only for a short time because of the weather. It keeps replenishing the ozone.
Ststistics on how littering messes up the ozone layer?
Short answer: Unless the garbage is burned, there is little-to-no effect on the ozone layer.Burning organic matter can release chloromethane. About 15% of the chlorine-containing gases in the "ozone layer" are chloromethane, from both natural and Man-caused (burning garbage, burning forests) sources. This chloromethane is estimated to cause about 17% of the chlorine-caused ozone depletion.

No, they are different. Ozone depletion results in more ultraviolet (short wave) radiation reaching earth's surface. The greenhouse effect results in more infrared (long wave) radiation being absorbed by the atmosphere.
Would the process of the ozone depletion be more rapid during the day or night?
Depletion in the daytime would only be noticeable between days, or over years. There is always less ozone overnight. Ozone is made during the day, and decays when there is no UV-C to make more. On the other hand, there are some ozone destruction pathways that require light in order to complete the catalytic cycles... for example chlorine and bromine do require light (water vapor does not). Depletion is NOT a "short term" thing, that you can tell minute by minute how the ozone layer is doing.

Yes they are long term. They cannot be predicted for short term.
Is the current management of antarctica adequate to protect this unique environment?
the short answer is no.Antarctica is not being adequately protected, although there is an agreement between the countries of the world called the Antarctic Treaty, Animals which live is Antarctica are still being hunted and killed, animals such as, Seals, whales, fish and krill. Antarctica is also suffering from global warming and ozone depletion from human impacts. Tourism also is a huge problem in Antarctica, Animals can be killed or disturbed by people. Finally foreign animals a rubbish introduced disrupts this environment.

What are the causes and effects of depletion of ozone layer?
Short answer:Causes: Chlorofluorocarbons (CFCs) and other halogens (all man-made gases) emitted from industry rise to the stratosphere where ultraviolet radiation breaks them up and releases their chlorine. Chlorine destroys the ozone layer.Effects: Decreasing ozone means increases in melanoma (skin cancer), cataracts, famine (loss of arable land, and damage to crops). This would only occur in areas that had this thinning or hole in the ozone.More detailCauses:CFCs and related halocarbon gases are the main cause of ozone depletion all over the world. CFCs released from Western countries take several years to reach the stratosphere where the ozone layer is. During that time winds spread them all over the world. In the presence of ultraviolet light these gases release chlorine and bromine atoms which destroy some of the ozone in the ozone layer. This is called ozone depletion. The ozone hole is a related but different phenomenon.Effects:Earth's surface receives more UltraViolet-B, as ozone is the only gas currently in our atmosphere that absorbs UltraViolet-B. UltraViolet-B is also absorbed by soil, meters depth of water, and directly by the DNA of all surface life. DNA absorbing UltraViolet-B ends up increasing rates of cancer, mutation, and decreases crop yields. UltraViolet-B also causes cataracts to form in eye structures in animals (including Man).

What problems did CFCs cause?
The main problems with the use of CFCs is that when the CFC used, it is released into the atmosphere. Being stable and insoluble it does not easily get "washed" out of the atmosphere by rain. As decades past and the CFCs eventually reach the stratosphere, they are exposed to UV light which causes them to photo dissociate and react with the ozone and gradually depleting the ozone in the atmosphere. This allows UV light, which was blocked by the ozone, to enter the earth. The UV light is harmful for organisms.
Is the ozone thickening or thining?
No, depletion means thinning. The ozone layer is being depleted by chlorofluorocarbons which decomposes in the presence of short wavelength ultraviolet radiation from the sun. the chlorine radical produce in this reaction reacts with the ozone. The oxygen atoms present in the stratosphere reacts with the ClO to produce more chlorine radical.t herefore one chlorine radical produce can destroy many molecules of ozones.Thus a chain reaction is initiated.
How do CFCs cause the ozone hole?
Chlorine breaks off from CFCs and destroys the ozone. Ozone is a protective layer in the upper atmosphere. It is formed, when oxygen molecules absorb short wavelength ultra violet radiations from the sun. Ozone is mostly destroyed by free radicals in the atmosphere. When compounds like CFCs (chlorofluorocarbons) and other halocarbons are released, they are dissociated by sunlight into chloride radicals. These radicals attack ozone, thereby decreasing its concentration. This results in a thinning of the ozone layer, and in polar regions, a hole. The holes occur at the poles, and usually in Antarctica because of the extreme cold. During the winter polar stratospheric clouds form which are able to convert gases in the atmosphere into Cl (chlorine) and ClO (chlorine monoxide). When the sun arrives at the end of winter, that is the trigger to begin. This is why the hole is largest in spring.
How do you reduce ozone depletion?
Many things can be done to prevent depletion of the Ozone (Ozone Layer) (a little background...) Ozone is comprised of 3 oxygen atoms, known as O3. When we hear the term Oxygen, it is usually referring to the Oxygen that we breathe, known as O2. O2 is a necessary component for life (almost all life) on Earth's surface - it is the form of Oxygen that we breathe; it is used in cellular respiration in animals and photosynthesis in plants. Ozone, or O3, is in fact toxic to living creatures, but without it we would be in a lot of danger - So how does that work? Ozone, is naturally found in the upper level of our atmosphere. It absorbs many of the harmful rays of the sun, known as Ultraviolet radiation (UV-A, UV-B and UV-C) which can cause cancer and cellular damage. Pollution is a major source of depletion of the Ozone layer. Many man-made pollutants contain compounds called Chlorofluorocarbons (CFCs) and bromofluorocarbons. These compounnds can rise to the upper level of our stratosphere Where UV light breaks them into free radicals of Chlorine (Cl) and Bromine (Br). Each of these radicals is then free to react with O3 and catalyze a chain reaction capable of breaking down over 10,000 ozone molecules. IN SHORT- the compounds in Pollution from factories and aerosol cans can destroy ozone molecules, To prevent this laws have been passed to stop and control production of these compounds. You as an individual can help by lobbying in Congress, supporting environmental organizations and spreading the word to your friends, family and anyone you know about the causes and prevention of damage to Ozone.
