In Japan, Taiwan and South Korea, the government in a matter of years has put a lot of energy behind recycling food waste as livestock feed. It's environmentally friendly, it provides cheap livestock feed for the farmers in those parts of the world, and it avoids sending the food waste to landfill. Tristram Stuart
Popular culture bombards us with examples of animals being humanized for all sorts of purposes, ranging from education to entertainment to satire to propaganda. Walt Disney, for example, made us forget that Mickey is a mouse, and Donald a duck. George Orwell laid a cover of human societal ills over a population of livestock. Frans de Waal

The history of agriculture is the history of humans breeding seeds and animals to produce traits we want in our crops and livestock. Michael Specter
