I just came across some very interesting read. (Westeners forgive me if you have already came across or participated in this project- I know of no one in South Africa who has) The read was about the Mars One Project. It seems there are about 202 000 people who have already volunteered to take part!
Is Science giving us another home away from this planet? What are predictions of life in Mars? Is Mars stable enough with resources to cater for a 6billion odd of us humans,including other species like domestic animals (for our proteins, obviousloy)? How about plant life, marine life.
