Ms. Duggan: Labeling an opinion 'liberal/left' or 'conservative/right' is the enemy of effective discussion.  The value of this lawsuit is that it opens a discussion, or should, about the true progress of conservation of our planet.  Actions have consequences, we can no longer pretend they don't.  Without the controversial 'fracking' of oil sand, we may have run out of oil by now, with no realistic replacement.  The whole point of climate change is that we don't know the end result; ice age or stream bath?  We'd all like to stop before that point, not necessarily expecting a 'perfect climate'.  We do know our climate is already changing, in some areas disastrously, and these kids are worried.  Why aren't you?
