Many tv programs include a bit of ‘pro-green’ in their dialogue now.
Sometimes it just doesn’t fit the flow of the story line, but Hollywood has never let that stand in their way to push an agenda.
Don't forget the obligitory swipe at Conservatives and now most have added a scene where the lead actor tells someone not to smoke.
All propaganda for the masses.
Yes, I got a dose of this in Jericho last week. Some claptrap about all the deer moving north because of glowbull wormening. It was a complete non-sequitur and had no bearing on the plot at all, they just threw it in there to propagandize a little bit more.
