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.
More than 70 billion land animals are raised for human consumption each year. In 2006, the FAO concluded that the livestock sector was one of the top two or three major contributors to environmental degradation.
