What do Christians and global worming have to do with each other? It seems to me that in this culture weather your Christian or heathen, and wealthy it doesn't matter you are driving a SUV. Look at Hollywood and MTV, how many of them are Christians and how many destroy the earth? Movie makers, 20 cars in the garage and a limo for every show. Come on now, get a little real life on this stuff, the people, sports stars, movie stars and singers are not predominately Christian, but they waist the most, destroy the most and consume the most, so where are you even coming from? I bet you sit there watching some sports, listening to their music, watching movies/vidios, laughing and giggling or snapping your fingers to the latest radio toon when they are wasting all of these precious resources your talking about, come on now, put your thinking cap on.
You can make accusations against people who call their self's Christian, but if you look at the life of Jesus and if He is the definition of a Christian then the others may fall into the line of counterfeits, or extremely confused, and aren't we all?
No offense , but "A plea to Christians" seems so dramatic in this case IMO.
