It's just that people carry on. They don't build their life. They don't make conscious choices, orientate their actions or try to think about the society they live it.
They just go through it, going from one small short term objective to another, most of the time motivated by a small pleasure or to avoid pain.
That is why people get fat, get stuck in traffic going to a job they don't like, going back to TV eating unhealthy food and indulging some kind of addiction.
Believe it or not this is also a big cause of couples staying together, marrying, making children. Not the grand idea of love. Inertia. Status quo.
It's like when you have to do your homework but postpone it until the very last moment. Your profs tell you to work, your parents too, even your friends, and you know deep down that you're wrong, but you don't give a shit until you get the grade and think "if only I ...".
First world countries won't wake up until it gets bad (famines, war and mass immigration bad), until then it's just insects, birds and slightly warmer climate, surely people have bigger problems in their daily lives ...

I live in London. The stars are still clearly visible here.
Nowadays, I am happy to see a few bees around.
I think we are just too "busy" to step back, open our eyes and actually watch the world we live in.
