I am sorry if you have been indoctrinated by these environmentalists.

 It's obvious from your stated opinion, that you as well have fallen for indoctrination, from the deniers of human effect on our climate, though you see it as critical thinking, I would wager.
 
I applaud any attempt to engage or interest our youth in the involvement in, and the use of our governmental process, through the court system, or political structures. 
 
This case will stand or fall, based on it's merit, why the fear that these children will be the end of the world as we know it?
 From the mouths of babes, we might just stand a chance, more power to them.
