I see in my country many marriages at a young age and don't think about the economy in the future,
I know getting married at a young age is very beautiful,
but if the economy is insufficient, maybe should think again not to get married at a young age,
and I think from that marriage it can give birth to children and increase the population of the earth, and maybe in a few years the earth will be full of humans and surely there will be many other crimes to survive on this earth,
Is there a solution, to overcome this impending disaster
There is no impending disaster. It depends on how you look at it. You see, in the free world journalists are allowed to write whatever they want, and since articles about impending disasters draw more attention they tend to write more articles like that. If we were living in North Korea where it is forbidden to write anything except good news and articles telling how beautiful the life in the country is, we would feel much better, but I don't think that that would be a good solution. I don't want the life of a happy zombie neither for me nor for my children. So actually I'm not complaining about living in the free world, I just think we should pay less attention to what journalists are telling us.
Back to the topic. No, getting married at a young age doesn't lead to poverty. Ignorance, laziness, drunkenness and drug abuse is what leads to poverty in most cases. Having a wife and children, on the other hand, can make you work harder and earn more, and you can end up being more prosperous with your wife and children than you were before getting married.
