animals slaughtered for food in the U.S. has ranged between 8.9 and 9.5 billion since 2000. In 2015, approximately 9.2 billion land animals were slaughtered for food; 8.8 billion of these were chickens. The total number of farm animal deaths each year is considerably higher than the slaughter total, since at least tens of millions die before they are slaughtered. While there are no official statistics on the number of aquatic animals killed for food in the U.S., scientist Noam Mohr estimated that 56 billion sea animals were killed to feed Americans in 2011. Animal product consumption In 2013, American meat consumption was second-highest among Organisation for Economic Co-operation and Development (OECD) countries (behind Australia) at 200.6 lbs per capita annually. Cow consumption has been decreasing since the 1970s, while chicken consumption has doubled. According to a 2009 Food and Agriculture Organization (FAO), American egg consumption was higher than the developed countries’ average. Per-capita egg consumption in the U.S. climbed to 263 in 2014, the highest in recent years. Per capita availability of dairy products dropped from 339.2 lbs in 1970 to 275.9 in 2012. Vegetarianism and veganism 6% of respondents in a 1999 Gallup poll identified themselves as vegetarian, while 5% identified themselves as vegetarian a 2012 poll of 1014 respondents. 2% identified themselves as vegan in the 2012 poll. In a much larger survey (over 11000 respondents) conducted by the Humane Research Council in 2014, only 1.5% of respondents were vegetarian and 0.5% vegan. While these poll numbers do not indicate an increase in vegetarianism and veganism, plant-based diets and the consumption of fewer animal products seem to be a growing trend. Animals used for clothing Leather The United States is a major producer of leather. In 2012, it was the world's largest producer of bovine hide, and in 2013-2014 leather exports were among the highest ever. Fur 3.76 million mink were killed for their fur on fur farms in the U.S. in 2014. There are very few federal or state regulations on fur farming aside from labeling laws and bans on dog and cat fur trade. Americans trap and kill more wild animals for fur than any other country (up to 7 million annually), and the number of animals killed has increased substantially in recent years due to international demand. The steel-jaw trap, a trapping method widely considered inhumane and banned in over 80 countries, is legal
