The visible portion of the 13-foot-tall (4-meter-tall) Christmas tree isn't ancient, but its root system has been growing for 9,550 years, according to a team led by Leif Kullman, professor at UmeÃ¥ University's department of ecology and environmental science in Sweden. Enlarge Photo.
Here are the facts: 1  More than 100 million animals are reported killed by hunters each year.  The vast majority of species that are hunted -- waterfowl, upland birds, mourning doves, squirrels, raccoons, rabbits, crows, coyotes, etc. -- provide minimal sustenance and do not require population control.
Overview. 1  More than nine billion (9,000,000,000) land animals die each year in the U.S. alone to produce meat, dairy, and eggs. 2  Globally, the number of deaths exceeds 70 billion (more than six million animals every hour). 3  The number of aquatic animals killed is far greater, but they are reported in pounds, not lives.
