Oh brother. Sex is hard-coded into us. And for a reason.
That aside, it is not your call to say whether others have sex or not- you can choose not to, but if they want to proliferate it is their right, so there is really no use complaining about it.
It has been LONG proven that population growth can potentially increase the number of jobs. It has been supported NUMEROUS times throughout the course of history and it makes A LOT of sense logically. Now if you don't want to consider those things and just want to go off your intuition, then I have nothing else to say. If you are interested in the studies or examples I speak of, let me know and I can send you some links/reading, but I won't waste my time with it if you are just going to brush it off.
Do you think the industrial revolution was a good or bad thing? How about previous innovations in machinery and agriculture? Your concerns have been expressed plenty of times historically by those afraid of losing their jobs and time and time again they are proven WRONG.
That is a societal matter- a change in the way people think of their responsibilities. There are still places in the world where children do take care of their parents.
You are not a deadwood person. No one is. Stop giving yourself such little credit and realize that you too are a valued member of society.
Unless bringing more people into the world solves the hunger problem
Not saying it will, but I am saying that the homeless is not a result of too many people. I guarantee you that if we had 1 million people on Earth we would probably still have some homeless people- just like when we actually had 1 million people on the Earth.
