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.
farm animals are killed each year. Over 56 billion farmed animals are killed every year by humans. According to the Food and Agriculture Organization of the United Nations (FAOSTAT, 2008), this figure is expected to double by 2050. More than 3,000 animals die every second in slaughterhouses around the world.
