SCIENCE AND MATH Current important topics in today's world include "ecology" and "pollu- tion". Man is waging a futile battle to restore his environment which, because of a sinful nature, he is destroying. Any attempt by man alone will result in failure; he must have his "spiritual pollution" removed and a good relationship established with the Creator resulting in "spiritual ecology". —Donald P.Baumann Donald P.Baumann Iowa State University, Ph.D. Yearbook Advisor 50
