It's mostly just preaching to the choir, but they were innovative in their approach:
The film highlights the tragic consequences of the first triumph of the environmental movement, the ban on DDT, which has needlessly resulted in the deaths of more than 40 million children and adults in the developing world.Actually, I'd say the movie more than just highlights the consequences of the DDT "ban". More than 20 minutes were devoted to it with many graphic scenes of children dying of malaria interspersed with seemingly clueless rich white environmentalists saying how important the prohibition on the use of DDT is. While powerful, the case against the environmental movement and the claim of 40 million deaths seems significantly overstated.
Continuing on, the case against Climate Change Alarmism is straight forward. It basically amounts to saying, "See the catastrophe that happened the last time the environmentalist had their way? We'd better stop them from taking action against Global Warming or really bad things will happen again!"
The choir will no doubt eat that up, but those who belong to the Church of Warming are unlikely to buy into this logic since they very likely consider the reduction in the use of DDT a huge success, even to this day.
People who have not yet made up their minds, however, may be swayed because the malaria scenes are compelling. If the Warmenists are not able to produce enough evidence or propaganda in the media to convince those still deciding that much of the movie is untrue, the movie might convert a few more people to the skeptics side.
I hope it does.
