It seems as though humans have gone on a baby making spree and it isn't new, it's been on for a very long time now. Think about it, one man donating freely to a woman's womb who has given him access: and the result of their action is bringing more humans to the world. The effect of that? The number of resources available each human get reduced by the rate at which new humans are brought into the world.
Well, who doesn't like children and who doesn't like to do the stuff that brings children to this world? We all do, but this can be managed to reduce the risk it disposes on the economy of every nation. It's literally as if the increase in the population of we humans is directly proportional to the decrease in the strength of the world's economy.
It all starts with sensitization of every human possible, we all ought to know why we need to step on the break concerning the baby making spree. Yeah, the pleasure of it and the child(ren) are good, no doubt— but we are risking the economy not just for ourselves but the babies we are bringing into the world.
The resources readily available for use is believed to not be sufficient enough all humans on earth. It would be a survival of the fittest in terms of wisdom, value, money, connection, etc. Bringing so many children into world that seems to be unbalanced is quite wrong. I am not against having children but against having more than the number that can be catered for. When I was way younger, I knew families that had up to 5-7 children and the parents aren't doing well financially yet they keep giving birth till they got to 5,6 or 7. What do you want to offer this children, how do you provide for yourselves and these children. It's unfair!
With lesser population, many amenities can be easily managed with longetivity. Government could easily allocate resources and it would be sufficient for citizens. The rates of crimes committed will reduce drastically. Parents gets to cater for the right number of children they can handle, give attention and care to. Very slim chance of having young children wandering aroud without proper care from their parents. The society is safer, no more children that lacked basic home training growing up into adults that disturbs the society.
I believe having a law that restrict having more than a certain number of children will have a good impact on individuals, society, country and the world at large.
Meanwhile, there has to be a balance to when to stop such policy of number of child per parent. Workforce of the country has to be considered especially in important sectors like armed forces, health, farming, education, etc. I think it's a tough decision because both has it merits and demerits. A general sensitition program should be done to make the citizens aware of the effect over popular is having and will continue to have on the world economy.
