In modern society, young people increasingly prefer not to have children. Why? For what reasons could this be?

The deterioration of the environment affects the body in such a way that more and more often young people simply cannot have children. It does not matter whether it is a disease or a congenital pathology.
Personal choice. If both partners in a couple prefer not to have children. Travel together, enjoy life without taking on unnecessary worries and responsibilities.
Circumstances. Now residents of Ukraine are faced with the fact that having children can be simply unsafe. Taking responsibility for your life can sometimes be difficult. What can we say about a small defenseless child who has his basic needs. One of which is safety.

Yes, a family can exist without children, and this is a completely acceptable and common option. Family structures are varied, and the absence of children does not make the family less valuable or less important. I believe that absolutely any union of two people can be called a family - regardless of whether they have children or not.
