I feel like there could be a really interesting story behind this. You mention interesting concepts like interplanetary colonization, destruction of the Earth ecology, fascist government and extreme reduction in population. But the languag is difficult to read. There are lots of missing commas and bad grammar, making it difficult to parse some of the sentences. I get the feeling you are not writing idiomatic english, but translate more or less word-by-word from another language. I suppose writing skills comes from practice, so don't give up. Write down your story and go back to refine the language later.
