Before I post anyffin, I'd like to enlighten ye all that CFCs, the Ozone layer AND Global warming are different... but I'll explain the phenomenum of acid rain before I go on.

Now acid rain occurs when the rain from the atmosphere (H<span style='font-size:7.4pt;line-height:100%'>2</span>O from the surface of the earth that has evaporated over a period of time) falls through the clouds that contain a high conc of Sulphur... formed by burning coals and other oils. This mutated rain falls on the ground as what we call "acid rain" which is very dangerous... as it can pollute lakes and kill our plants.

Now to Global warming and the Ozone layer... well, I don't want to start repeating what Solidsnake76 has said... but just to add a bit.

Imagine 2 jars filled with water. Place them out in the sun. One opened and the other one closed. After a period of time, the one that was closed would become hot and steamy while the opened one would pretty much be the same ("culled from Jok R. Church). Now what happens here is that the heat from the sun had no where to escape.

The same thing goes with the Carbon that is being released into the atmosphere. It somewhat inhibits the "bad energy" emmited from the sun. The reason I call this "bad energy" is because we get a lot of energy from the sun that's good... and we as humans put into good use. but this bad energy commonly known as Ultra violet radiation. So with all the Carbon running around from the stratosphere, to the atmosphere... you can simply look at it from the point of the earth being placed in a tremendous jar... and the heat from the sun not having any chance to escape. The earth not being able to cool of... so to speak. Hence your case of global warming.

As for the Ozone layer, which is another different case entirely, this is like a special type of Oxygen. O<span style='font-size:7.4pt;line-height:100%'>3</span> to be specific. Now, Oxygen as you'll know is diatomic... but Ozone is triatomic. Unfortunately, this Ozone is not that strong... however, it's the right shape and size to absorb the Ultra violet rays coming from the sun.

Thus you can call the Ozone layer the earth's sun glasses :biggrin:

Anyway, this Ozone layer is being depleted by checmicals known as CFCs (Choloroflorocarbons.. a mixture of Chlorine, Carbon and Flourine) These are the chemicals you'll see in spray cans (in the past anyway) and in refigerators to puffup plastic foam. Spray cans in the USA do not contain CFCs anymore.

So that's just to show you the distinction between those 2 effects. You might say they're both related in a certain way.. but they are both 2 different problems faced by the earth that should be resolved.

You wanna know why your elementary school teacher always told you to plant trees?? :biggrin:

Well, here's the deal. These trees you plant use up Carbon (IV) Oxide (yeah.. I'm British baby :biggrin: ) and they store up the ones that we release from burning wood, oil or other stuff... ala huge chemical industries.

Ceteris Paribus, this Carbon (IV) Oxide can be stored for use by the plants and thus, does not have to place the earth in a huge jar to prevent the escape of the heat from the sun :biggrin:
