Textbook Question
Chapter 8, Problem 1AC
Some years ago a freight train overturned, spilling a load of grain. Because the grain was unusable, it was buried in the railroad embankment. Although there is no shortage of other food, the local bear population has become a nuisance by continually uncovering the grain. Yeasts are common in the soil. What do you think has happened to the grain to make the bears keep digging it up, and how is their behavior related to human cultural evolution?

However, new bacteria are evolving that are resistant to antibiotics. When someone uses antibiotics, they often contribute in a small way to an increase in the number of bacteria that are resistant to antibiotics. How would an economist classify antibiotic use? Public health officials are concerned with the overuse of antibiotics, which leads to bacteria being resistant to antibiotics. What is a solution to this problem?arrow_forward
