There's nothing man can do.
This current "system" is scheduled to reach its end. And soon.
Jesus Christ will return and end the rule of man and establish his kingdom.
The return of Jesus Christ is the blessed hope. A sure thing.
Until then all will continue as before, getting worse by the day.
What is getting worse by the day? Medical science and technology is solving many world problems. People are getting happier, healthier and living longer with every passing decade. Wars and famine are becoming less frequent compared to centuries past. What exactly is getting worse?
