There has been such a simple equation for me to describe today's society, solving all the problems, and I don't think it's too far off. I'm quite surprised that all human beings haven't grasped this fact, yet. Adding people
Aside from evolution, overpopulation.
I live in an apartment surrounded by crying babies, who will end up with a lot of competition to deal with.
Lots of noisy kids at the supermarket, but nobody speaks to anyone, any more.
Transport
Food
Energy
Environment... sewage
From my work, I know that transport can give way to communication networks, but not completely. The last decade of change on roads and rail, where the infrastructure is similar, but the number of people has crippled it.
Some luxuries have slowly improved. It's not worth valuing. The rest has got worse. Space.
With less people, we'd all be a lot happier.
Why do humans still have an animalistic desire for breeding, and not curb it, on a planetary scale? Why is there a feeling of success in breeding? It should be a crime. I wish there was enough intelligence to think beyond animals' psychology.
