I suppose I am left with a question: in order to sustain and prioritize human life, whose life are we taking away? What about the animal world ? Because we are already doing that , every minute of every day - we kill the animal world in order to allow the human world to survive. So if we agree with this thesis - to honour human life - do we not automatically agree with the requirements - with the fact that we would continue killing all other types of life? What makes human life that much more valuable ? What have we, as humans, created that has bettered every other species? Because nature has done that. What if for nature to survive - humans have to choose to sacrifice, even themselves ? Why is that so unthinkable ?
