In nature, biological equilibrium is attained by predator-prey relationships. However, this is achieved in human beings by family planning and birth control. Family planning is a device by which couples determine the number of children they want and when they want them.

Birth control refers to the method used to prevent a woman from becoming pregnant for as long as she wishes.

Without family planning, the population of a nation can rise indiscriminately and may not be able to match the available food and other resources. Famine and death can eventually result.

Family planning is all about prevention of pregnancy and not a termination of life. Carefully planned family planning prevents unwanted pregnancies. The birth control or family planning devices include the following;

  • Use of condom
  • Sterilization
  • Spermicides
  • Intra-uterine device (IVD)
  • Contraceptive pills or injection
  • Rhythm method
  • Withdrawal method
