There has been a lot of talk, among scientists and sci-fi enthusiasts alike, over the past decades, over whether life on other planets exist, and whether, if it does, this could be the saviour of humanity. We assume that if life on other planets exists, this would be a good opportunity for human habitation there. But would this be a good idea?
In the past, when people, especially tose in richer countries such as European ones and now America, have discovered new lands, they have colonised them, and this has often been good for the inhabitants of those countries, as they now have more space to inhabit and new chances in a new world. It is often assumed that this is what would happen if humans found life on another planet, as it would be good for humanity.
This would be true. It would be an escape of refuge from our dying planet, and would save lives, potentially. However, I think it would not be a good idea. In history, when richer countries have colonised newly discovered, not as powerful ones, it has often destroyed them. Colonists havebrought new diseases which the natives of those places were not immune to as they were, and therefore become sick or died, they have taken them into slavery, persecuted them, forced them to speak their language and follow their religion. They have brought animals to their country which have been invaders and killed off their native animals. Generally, they have treated the inhabitants of the newly-discovered land badly. There is nothing to say that we would not do this to the life of other planets. Yes, we may have stronger morals of equality, but the spread of foreign diseases on their planet could not be helped. Would we want to bring this on the creatures of the planet? Or would humans be considered more important than them, and therefore a priority over their health, as the colonists believed with the natives, so infect their planet?
What are your thoughts?
