There was once a little grey planet mat was very sad. The people living there didn't look after it. They polluted me whole planet so much with rubbish that there were no plants or animals left.
One day, a little boy was walking on the planet when he passed a cave (洞穴) and noticed a small red flower inside. The flower was very sick, almost dying, so the boy carefully dug up the flower with roots, soil and everything. Then he started looking for a place where he could look after it. He searched all over the planet, but everywhere was so polluted that there was no place the flower could possibly live in. Then he looked up at the sky and noticed the Moon. It seemed to the boy that maybe the plant could live there. So the little boy put on his astronaut suit, and climbed into a spaceship. He put the little red flower in the back, and they went to the Moon.
Far away from all that pollution, and with the boy visiting it every day to take care of it, the flower started to grow. The flower was so well cared for that it soon germinated, giving birth to others, and these other flowers spread onto other flowers. Before long, the whole Moon was completely covered with flowers.
That's why, whenever the little boy's flowers open up, for a few minutes the Moon turns red, like a warning light. Maybe it's telling us that if we don't look after our planet, the day will come when flowers will only be able to grow on the Moon.
