The atmosphere on earth is getting 'dangerous'. Except it's ok, because we've inhabited the moon and a portion of mars. The entire population will be transported. That is, not including the three billion that have been sacraficed in order to keep the population under control. These sacrafices will be transported across the planet to camps, where they will be gassed painlessly. They should be proud to be saving the rest of human race. Pride is what they should feel as they die.
This is a dystopian story of separation in a world already torn apart. And a story of true courage and bravery in a world of cowardice.
