First, nice to see a serious effort. Liked the set up in the old church.
No doubt the riots in Boston were pretty sweet. We know how to riot up there. Old School.
The ozone hole isn't the main problem. It's the build up of carbon emissions that, according to some, is causing the green house effect and global climate change, such as the shrinking of the polar ice caps, Iceland, glaciers around the world.
It serves as a good set-up, however, to the dire conditions of the church and the young man (Name, please) desperate enough to eat a dog (without being tied to a chair and the additional benefit of having it barbecued)

A little sparse, but a nice job.
