Competition seeding story examples - for patriciama

I need to get 50 samples of children's stories (5yrs to 10yrs) with the theme of global warming (melting ice caps, greenhouse gasses, air pollution, acid rain, etc). We need these to show on our site examples of what children can produce for competitions we will be holding for children to enter. They will be simple examples in .doc or .rtf format, be no more than 100 words each and be written in the mode of an English schoolchild. They must be original pieces.
