I believe we are (or always have been) part of our own Demise in this World. We will get to a point of no return that will eventually lead to the extinction of most life as we know it, including the human species
I find this a natural process. Similar to death. After us the universo will continue its course and probably New forms of life will emerge. We've seen these masa extinction happen before. Life always finds itself back.
I find it futile and even selfish to believe that we will be here forever. Things seem kinda gloom in the near future. Perhaps our time here is near an end. And that's fine and quite natural.
What I do believe is bad is that the generation before this masa extinction will suffer and have to en dure harsh lifestyles due to the choices we make today. I find myself pondering about this often and believe that what I can do to help this is just not have children. If at some point I want to start a family I'll probably adopt.
What is your stance on the (probably inevitable) extinction of human kind?
