“Hebrew word for "charity" tzedakah, simply means "justice" and as this suggests, for Jews, giving to the poor is no optional extra but an essential part of living a just life.”

“To give preference to the life of a being simply because that being is a member of our species would put us in the same position as racists who give preference to those who are members of their race.”

“The notion that human life is sacred just because it is human life is medieval.”

“If morality is always relative to one’s own society, then you, coming from your society, have your moral standards and I, coming from my society, have mine. It follows that when I criticize your moral standards, I am simply expressing the morality of my society, but it also follows that when you condemn me for criticizing the moral standards of your society, you are simply expressing the morality of your society. There is, on this view, no way of moving outside the morality of one’s own society and expressing a transcultural or objective moral judgment about anything, including respect for the cultures of different peoples. Hence if we happen to live in a culture that honors those who subdue other societies and suppress their cultures, then that is our morality, and the relativist can offer no cogent reason why we should not simply get on with it.”

“As far as food is concerned, the great extravagance is not caviar or truffles, but beef, pork and poultry. Some 38 percent of the world's grain crop is now fed to animals, as well as large quantities of soybeans. There are three times as many domestic animals on this planet as there are human beings. The combined weight of the world's 1.28 billion cattle alone exceeds that of the human population. While we look darkly at the number of babies being born in poorer parts of the world, we ignore the over-population of farm animals, to which we ourselves contribute...[t]hat, however, is only part of the damage done by the animals we deliberately breed. The energy intensive factory farming methods of the industrialised nations are responsible for the consumption of huge amounts of fossil fuels. Chemical fertilizers, used to grow the feed crops for cattle in feedlots and pigs and chickens kept indoors in sheds, produce nitrous oxide, another greenhouse gas. Then there is the loss of forests. Everywhere, forest-dwellers, both human and non-human, can be pushed out. Since 1960, 25 percent of the forests of Central America have been cleared for cattle. Once cleared, the poor soils will support grazing for a few years; then the graziers must move on. Shrub takes over the abandoned pasture, but the forest does not return. When the forests are cleared so the cattle can graze, billions of tons of carbon dioxide are released into the atmosphere. Finally, the world's cattle are thought to produce about 20 percent of the methane released into the atmosphere, and methane traps twenty-five times as much heat from the sun as carbon dioxide. Factory farm manure also produces methane because, unlike manured dropped naturally in the fields, it dies not decompose in the presence of oxygen. All of this amounts to a compelling reason...for a plant based diet.”

“Forests and meat animals compete for the same land. The prodigious appetite of the affluent nations for meat means that agribusiness can pay more than those who want to preserve or restore the forest. We are, quite literally, gambling with the future of our planet – for the sake of hamburgers”

“In the past 20 years alone, it adds up to more death than were caused by all the civil and international wars adn government repression of the entire twentieth century, the century of Hitler and Stalin. How much would we give to prevent those horrors? Yet how little are we doing to prevent today's even larger toll and all the misery that it involves? I believe that if you read this book to the end, and look honestly and carefully at our situation, assessing both the facts and the ethical arguments, you will agree that we must act.”
