I cannot say it better than a Youtube commentator:
"Christians working together to destroy the planet.
Bravo. It's exactly what Satan would want you to do."
The Bible warns against these kind of people at 2 Corinthians 11:13-15:
“For such men are false apostles, deceitful workers, disguising themselves as apostles of Christ. No wonder, for even Satan disguises himself as an angel of light. Therefore, it is not surprising if his servants disguise themselves as servants of righteousness, whose end will be according to their deeds.”
What's that last line mean -- "whose end will be according to their deeds"?
I think it means these folks are going to die of cancer because they preached the devil's gospel, which is that toxic sludge is good for you.
