Is it better for the Earth if humans are herbivores, carnivores or somewhere on the omnivore spectrum? Some biology books claim the correct answer is "herbivore" because plants can better sustain human life than animal meat. Commentator John Richard Schrock disagrees. And he points to new biology textbooks that he claims are full of faulty science.
Commentator John Richard Schrock is the director of biology education at Emporia State University, where he trains future biology teachers. He's also a regular contributor to Kansas Public Radio.
