According to the Food and Agriculture Organization of the United States (FAO) it's estimated that by 2015 the world will consume a collective average of 41.3 kg of meat per capita (about 91 pounds). That number is expected to rise to 45.3 kg (about 100 pounds) by 2030. However, when you take into account the fact people in the U.S. ate an average of 203.6 pounds of meat per person in 2013 alone, it's clear there is a mix of moral and ethical perspectives when it comes to eating meat.
Many animal rights activists believe livestock are mistreated during production, live in unhealthy conditions, and feel that factory farming causes imminent danger to the environment. The farmers counter that they supply an essential commodity to the economy, assert the majority of meat producers farm ethically and take no moral issue with eating animals—a practice humans have been doing for at least 2.6 million years. These explore the pros, cons and questions surrounding the controversial topic of eating meat.
