Plans for humans to leave Earth and colonize new worlds are underway. Scientists in Japan are conducting experiments on mice sperm to see if they survive, and how they are affected, by space travel. Other scientists seek to answer difficult moral questions about giving birth to children in outer space, given that we know the environment to be harmful to the human body and spirit. "Philosophers call this consent to risk," explains Cameron Smith, an anthropologist at Portland State University in Oregon. "Is it morally acceptable to put someone else at risk without their consent? That is, to have a child in those conditions?"
