Annually, over 65 billion animals are killed for food, and 40-50 million animals are killed for their fur. Public concern for the physical and psychological well-being of these creatures has helped regulate the industry, but “ethical treatment” standards still vary country by country. The use of crates, for example – small cages designed to virtually immobilize the animals inside them – is still widely practiced outside of Europe. In many cases, meat production methods pose health risks for consumers. Additionally, evidence increasingly shows that the human appetite for meat is a driving force behind nearly every major category of environmental damage. Because meat production accounts for nearly a fifth of global greenhouse gas emissions, the UN suggests that the developed world cut its meat consumption by 50% per person by the year 2050. Others advocate mindful meat eating.
