Re-making the World

According to Professor Mautner humans have a moral responsibility to “seed” Earth life through the galaxy. Panspermia may be a useful policy for far-future human survival. I’m really not the person to give a considered response. However, I can’t help but notice the similarity of thinking to that which encouraged shifting plant and animal species around the globe under the whim of European sailors and settlers. Australia has feral populations of goats, camels, water buffaloes, etc as a result. Let’s not mention the rabbit plague. In other places the results for indigenous species were even worse. Throwing species into unknown environments has unknown consequences. Is the risk worth it? How do you calculate the risk? and, as with all space activity, can you justify the money?
