Heero in “Unfinished Business”

Heero

Earth, the planet in the solar system that miraculously gave birth to life. In the year After Colony 195, with the development of the colonies people now live in new surroundings, thanks to plentiful natural resources and cultivated technological abilities. However, this new world is nothing but an imitation of humankind's motherland the Earth. But why were the colonies made in the first place? I hear the main purpose was technological development to improve the lives of human kind on Earth. Did human kind start asking too much from this imitation world? The self-sustained way of life is more stable than life on Earth especially since it lacks the risk of natural disasters.
