Having a limit in every case is very essential because crossing the limit can't bring anything good. Too much love can spoil one, and too much punishment may create a monster. So he's better off understanding that there is a limit for everything, and within a limit, everything can be balanced, and it's the same for the population.
The population of the world is increasing, and for many countries, the population size is too large, and it has already become a headache. At the current time, the top two countries in terms of population are India and China. The population of both countries is almost very close, and that may give you the feeling of how they are managing a vast population. I think rather than focusing on only population, we need to focus on the population density. If a country has a larger area, then the large population is not an issue because with land, they must have the resources to support the population of the country.
So it's not necessarily that the population is a trouble for a country if that country has a larger area. But those countries that have a small area with a higher density of population are in trouble because the government of the country can't provide or ensure good facilities and services for the population. Because of a lack of resources, the country cannot move forward easily. Lack of resources means poverty, and because of poverty, ensuring job facilities for people is difficult, and for survival, people may choose the wrong way and turn into criminals. Because of that reason, most of the country has a high crime rate.
I am from Bangladesh, and it's one of the overpopulated countries. Naturally, till now, population is an obstacle in my country because our government is yet to find a way to utilize the power of the population. The good thing is that the increasing rate of population of my country is not so high like it was in the past. I think it's because in the present time, people living in my country are very well aware of the situation, and they know better about family planning. They know that raising a kid is not a matter of a joke, and it's highly related to finance. So they make decisions carefully.
So many people in my country don't have this knowledge about family planning, and need to understand many things about family planning. If parents are capable enough to raise several kids and give them a better future, I think it's good for the country because those children will be an asset for the country rather than being an obstacle. There is no way the government has the right to control family-related decisions. But the government can do some campaigns to raise awareness about family planning, which can be very effective.
The population can be an asset if the government can utilize it properly, and I believe that someday our government will be able to utilize our population and convert it into an asset.
