I've heard about this thing. I even read that the U.N. would lead us into earth worship. Agenda 21 would cut our energy in order to save the planet. This is a bad thing, which means:
No CathInfo, since our Internet access would be deprived due to electricity cut;
Computer geeks like me would be boring;
We would fall back into feudalism (which is not a problem for the Amish) or the Paleolithic.
Our life qualities would fall and starvation will appear and diseases such as the plaque, leprosy and cholera will come back.
The Islamic oil countries would start to conquer other countries due to their petrol deemed as harmful to the planet.
And if they want to eradicate Christianity, demonic phenomea would be risen.
Since computers, good quality life and Jesus are all important in my life (but nothing beats Jesus!), we need to take action. If you dislike Agenda 21, switch to Linux. It is alleged that Bill Gates supports it.
