Footprints in Carbon

So what is a carbon footprint? Ever since the Dems in the US Congress decided to take over the world, starting with something called Cap and Trade, not to be confused by Cap and Gown, folks are trying to make money on reducing their carbon footprint. I did not know my footprint had carbon in it. And, trust me, with two teenagers and two dogs at home, we have plenty of footprints around here. And, after being pregnant twice, I can tell you there is no reducing my foot, no matter how many times I tried to squeeze my enlarged foot into my former size 7's.

So, I looked up carbon footprint on Wikipedia, or where guys without dates write fake definitions online, and got this:

" A carbon footprint is "the total set of GHG (greenhouse gas) emissions caused directly and indirectly by an individual, organization, event or product"

Like I know what that means. So, how can I reduce something if I am not sure what it is? So, I asked my teenager who, of course, knows everything, and was told that it is how green I am. So, I guess I am in good shape as I have green shoes, a green purse and even a green coat!
