Very little connection between the ozone layer and greenhouse gases.
Natural causes of ozone depletion are the OH- ion and the NO- ion however these have been depleting the ozone layer at a sustainable level since it was formed.In the mid 70s it was discovered that the ozone layer was being depleted and the hunt was on for the cause. Very quickly chlorofluorocarbons and bromo-fluro-carbons were found to be the culprits.These gases were primarily used in aerosol cans, air conditioning units, refrigeration cooling units and to clean circuit boards. Once released into the atmosphere ultraviolet radiation causes the CFCs and BFCs to split and release the dangerous Cl- and Br- ions into the ozone layer.These ions are highly reactive and readily split ozone to form oxygen molecules. Unless they react with other substances such as hydrogen chlorine and bromine ions can continue to catalyse the break down of ozone for a number of years.CFCs were banned for use in aerosols in the USA in the 70s but public and political opinion over a widespread reduction was muted and apathetic for nearly a decade until new discoveries were made in Antarctica. Atmospheric scientists discovered that the southern continent had a hole in its ozone layer and that it was growing and caused by BFCs and CFCs. Further studies discovered a hole over the north pole too.These new discoveries prompted an international movement not simply to reduce the level of CFC and BFC output as had been mooted for years but to completely and utterly ban them except for the most vital uses. In less than a decade this goal was achieved.One of the replacements hydro-chloro-fluro-carbons are less damaging but still contribute some damage to the ozone layer. New disposal laws came into force to help with the recycling of many materials containing HCFCs, CFCs and BFCs to avoid the release of these into the environment. Unfortunately due to the cost most 3rd world countries don't follow these procedures and, in fact, many of the 1st world countries have vast backlogs of refrigerators and freezers requiring recycling that are slowly leaking their coolant into the atmosphere.The effect on plant and animal life has been marked. The human cost has been indisputable with marked rises in skin cancer at most latitudes particularly in the extremes of the North and South. Some South American cities have had to cope with having no ozone layer for years.Hydro-fluro-carbons have replaced HCFCs for many applications but whilst these don't damage the ozone layer they are greenhouse gases and contribute to climate change.
We can control the things we are doing that we know have effects on the ozone layer. We are not big enough to stop Nature from doing what She also does to the ozone layer from time to time. Please check the answers to questions like: How can we replenish the ozone layer?

Each Canadian is responsible for about 18 tonnes of greenhouse gas in a year. Like most industrialized nations Canada develops inventories of all pollutants each year through Stats Canada, Environment Canada and the NPRI. These indicate GHGs as well as other pollutants. The data at the links indicates values of slightly over 650 tonne per year. With a population of about 34,482,779, the per capita Canadian GHG production from human activities would be about 18 tonnes per year.

The problem with the greenhouse effect is that all the CNN and FOX science shows have "heat" from the sun hitting the earth and bouncing back towards space only to be intercepted by a layer of CO2 "up there" reflecting it back down like the glass in Greenhouse. Whereas the actual effect is that the heat is absorbed by the CO2 and other GHG gases all through the atmosphere. This is the same picture as folks have of CFCs rising to the stratosphere to form an ozone eating layer, where in reality it just mixes all through the atmosphere and the top (outer) edge reacts. Links which cover this in more detail are appended

Some of the harmful gases which are rising in the atmosphere and are major cause of atmospheric pollution are (in no particular order):Carbon monoxide (from incomplete combustion of fuels... no choice, toxic to breathe),Sulfur dioxide and nitrogen oxide (from industrial and vehicular exhaust, causes of acid rain, irritates air passages),Chlorofluorocarbons (CFCs, refrigerant discharges, causes destruction of the ozone layer),Mercury emissions (from industries, fluorescent lamps and the burning of coal, potentially toxic),Carbon dioxide (fossil fuel burning and greenhouse gas),Methane gas (cow farming, landfill emissions and natural sources, greenhouse gas),Volatile organic compounds (from fuel vapors, solvent, paint, etc. Really includes methane too),Ozone (which is bad at low altitudes and does not survive to replenish the high altitude ozone layer which protects us from UV light)See the Web Links for more information.
Coal is a fossil fuel which holds carbon which has been trapped underground for millions of years. When it is burnt the carbon dioxide is released where it adds to the greenhouse gases in the atmosphere.
All gases react to infrared (IR) to some degree. Also, there are a range of energies (frequencies) in the IR region. But some gases are much better at absorbing IR than others, and we assign the term "greenhouse gases" to them. Among these is carbon dioxide (CO2), chlorofluorocarbons (CFC's, which are a family of compounds containing carbon and fluorine), methane (CH4), nitrous oxide (N2O), ozone (O3) and even water vapor (H2O).These gases are increasing in concentration in the atmosphere, and they're causing a general "warming" of the earth. This spurs climate change on a global scale. We clearly admit that the climate of the earth has changed many times in the past. And it continues to do so today; it's a "living" mechanism. But man's contribution to the increase in the speed, the acceleration, of these changes by dumping these gases into the atmosphere cannot be ignored. The increase in greenhouse gas concentrations, and, therefore, the increase in average global temperatures (and associated climate change!) is more than dramatic. The rapid changes are destructive, and the wise person would not get hoodwinked by believing anyone saying these changes are not dangerously accelerated by man.The door is open to understanding the relatively simple chemistry of the greenhouse gases, and also to the much more complex changes in global climate driven by what man is doing as regards emitting them. Links below will get you started down a path of broader understanding. Even if you're not a chemist, atmospheric scientist or other "high power" investigator, you will be making decisions which have far reaching effects on the planet and the lives of man (and everything else!) in the future. If all you do is vote or recycle or even consume, you are a part of the mechanism. Educate yourself, think it through and make a considered choice about where you want to be in the cycle. Then take a firm stand.A:All gases absorb some infrared radiation, but the strongest absorbers are the "greenhouse" gases: primarily carbon dioxide, methane, and nitrogen oxides.

Links between particles in a substance...hmm....this is a tricky one, but if I'm right, it should be ATOMS. Does that fit?
