How we should control population growth by family plannning​
Ostrovityanka [42]

Answer: Family planning is a measure that can help control the number of babies around the world.

Explanation:

High birth rates tend to occur regularly in countries where there is a high rate of poverty in various environments. These people who are in these environments generally have a low level of education and few resources, which do not allow them access to greater knowledge about the importance of planning.

To control the growth of the world population it is necessary to educate the people. Families should be taught about the importance of having a number of children and how more can affect various aspects of their family. The birth of a baby is something that in most cases generates emotion but when it is done without consciousness, where the parents do not think how their current situation can affect the baby, it is something that will bring negative results for everyone.

personal, comfortable, and reciprocal.

Explanation:

According to my research on political parties and their relationships, I can say that based on the information provided within the question the relationship among these groups can be described as personal, comfortable, and reciprocal. This is because they are groups that work very closely with one another and need to ford a certain comfortable environment of trust since each one does something for the other and vice versa.
