This Scientist Might End Animal Cruelty

Maybe you've watched the undercover video: A farmer presses a hot iron into the scalp of a wide-eyed calf, burning away tissue that is beginning to turn into horns. She writhes, moaning pathetically, and collapses in the dirt.When Scott Fahrenkrug saw that footage, released by Mercy for Animals in 2010, it made him sick to his stomach. Most of the roughly 9 million dairy cows in the United States have been dehorned—with an iron, clippers, or caustic paste—to protect handlers and other cows.
