Well, this is the place! If you don't know what is this topic meant for, there is a topic in Show and Tell here, explaining what this project is.

Now, I would like to hear your suggestions for this wonderful project, because this project has potential! Anyway, just some rules that you need to follow when posting here:

(1) I DON'T WANT REDUNDANCY. This means that when one thing was already suggested by another person, don't post that thing again. You can just say “I agree with person x” and the like.
(2) Please don't suggest things that are already in the project. That is why I requested you to check the link above to be guided by it, right?
(3) No spamming. When no one sees any suggestion, please don't bump it. I'm always active and I'll check your replies from time to time.

Well, let's get the suggestions rolling! Please remember the three rules when posting here. Thank you!

Ok what are you asking for? I dont understand “ideas for world population” what do you mean by “ideas”

Sorry for the misunderstanding there. I actually meant “Any ideas for my world population project?”
