As stated earlier, most high school and university biology textbooks used in the United States do not present any scientific arguments against the theory of macroevolution. The failure to do so may lead a student to conclude that he or she is in fact the result of random, chance processes, and has not been created or designed for any special purpose. This in turn can have a devastating impact on the student, leading him or her to devalue human life and possibly engage in drug abuse, sexual promiscuity, or violence, or even commit suicide.
It is critical that a scientific theory that has potentially disastrous social consequences be presented objectively. The cause of truth and the general welfare of society are both promoted if the scientific arguments both for and against the theory of macroevolution are presented.
