According to the U.S. Department of Labor, Labor Day “constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.” But because of homonyms, this Labor Day also finds Animal Planet paying its own tribute by streaming birthing farm animals until September 1. Those who can stomach it can tune in right now to the Nebraska State Fair Birthing Pavilion, which will be showing animals in and out of labor around the clock.
