The Bible certainly tells us not to pollute his earth.
“Global warming” is junk science. CO2 isn’t pollution. Neither is NO2, or any of that other inert crap. I think we can all agree pollution causes direct, measurable harm to plants, animals, and humans.
If they want to speak out against Biblical pollution, perhaps they should discuss the radioactive sludge oozing out of Fukushima, or the toxic fumes coming out of D.C.
The issue isn't so much pollution when it comes to Global Warming nonsense - as you pointed out, NO2 and CO2 are not pollutants.
Too many "higher ups" in religions keep getting diverted fro Biblical truth and start preaching personal crap that does nothing to spread the Word and the Good News - they don't belong in their elevated positions as they are wasting them on superfluous crap instead of doing what they should.
