If we are all interested in harmony everywhere (with nature, with other people), so that we are all as one (different, but like brothers and sisters to each other), then why are we not moving in this direction?
We are not moving in this direction for two reasons:
1. Some people don't want to move in this direction;
2. Some people like this direction only if they can be the boss of everybody else.
If all people are united, there will be no shortage of anything. It will be beneficial for me that people around me live well. Even, for example, a bandit or a swindler will benefit from it, because he will be able to apply his skills in a slightly different direction, and people will love him for the fact that now he helps everyone. Don't we all want this?
Seems to me that it is when people are united that there is trouble. Why? Because everybody thinks at least a little differently than everybody else. This means that "united" only means being united physically. When other people who think differently than you, get too close to you physically, there is irritation that can flare into hostilities.
But you need to "wake up" for this (at least some large part of society). If you woke up, if you don't see the point in aggression and ignorance, then show people by your example how great it is to live in harmony with yourself and with the world around you. Over time, people will see this and will also become more sane. This is just a small effort that can change the world! And it all depends on each of us! Bring goodness to this world, this is the only real value!
Actually, there is only one way for this to happen. People need to follow the Holy Spirit, Who Jesus sent to bring people to Him, until He returns in power. Why the Holy Spirit? Because He is the only One Who can read the minds and hearts of all people, so that He can direct them properly.
A second way might be for everybody to be hooked into his own neural net, all of which are attached to a super AI computer, which can direct the world by integrating the thoughts of all people in the best way. But this is such a faraway fantasy, that there really is no reason to consider it. Besides, if the AI has corrupt ambitions, the people will be corrupted.
The only real way is to get into the Bible, get to church, learn to believe in the coming New Kingdom of God, and be saved by Jesus.
