Planet earth being full is one of the most common misconceptions. It’s staggering how many people believe this ignorantly without doing any research. In fact every person alive today could stand shoulder to shoulder and fit in New York city itself. Aside from that blatant misinformation how can a concept of space ever trump the protected value of human life? I would like some more room can I kill you and take what land you possess? That’s how the United States was formed after all, taking land from indigenous tribes so maybe you are onto something.
