Overpopulation is when too many populations disrupt the balance of the environment. Everything will be maintained if the population balance is in control. Population can be brought under control without any population decline through lifestyle changes. Demographics can be applied to a specific nation or the entire world if countries think carefully.
Anything extra in the world is harmful be it nectar. So we can get rid of it by applying a little awareness. As I have seen earlier my grandmother used to cook curry and when the amount of salt in the curry was high, she used to leave a few leaves of malabar spinach in the curry for some time. And after a while he would remove the leaves from the curry to reduce the saltiness a bit. Similarly when the population of a country increases if the people of the country can be converted into public resources then I believe that the problem of population growth can be solved.
I heard a long time ago from my grandmother that love can be poison if it is too much. Now I fully believe this as my father used to give my younger brother everything whether he needed it or not. And now he has become so disobedient that he treats his father very badly if he cannot fulfill his huge demands which are impossible to fulfill. Now I often see my father crying.
However, if the country's population is high and they cannot be used in the necessary areas then it will become a poison for the country. So if they can be used in the required fields by increasing their skills then the overall development of the country seems to happen.
i am sorry for what your father experienced, actually your little brother was raised wrongly, your father should not have spoiled him so much, personality disorders are something that is often experienced by those who were spoiled too much as children.
From the news that i read, 56.5% of workers in the manual sector in Japan are Indonesian citizens. Well, actually the distribution of the population is very good, but you need to know that there are several types of people who cannot be accepted carelessly, including asylum seekers from countries at war or residents from overpopulated countries, they can become pests.
