“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”

“The principle of fair reduction is based on the concept of historic responsibility. Developed countries finished industrialising first. Thus, over the last 60 years, the developed countries, which represent 17 percent of the world's population, have been responsible for 70 percent of carbon emissions. The developed countries should adjust for this disparity accordingly. In contrast, developing countries, which represent 83 percent of the world's population, have contributed only 30 percent of total carbon emissions over the past 60 years. It is therefore fair to give developing countries more leeway to produce carbon emissions.”

“In an earlier stage of our development most human groups held to a tribal ethic. Members of the tribe were protected, but people of other tribes could be robbed or killed as one pleased. Gradually the circle of protection expanded, but as recently as 150 years ago we did not include blacks. So African human beings could be captured, shipped to America, and sold. In Australia white settlers regarded Aborigines as a pest and hunted them down, much as kangaroos are hunted down today. Just as we have progressed beyond the blatantly racist ethic of the era of slavery and colonialism, so we must now progress beyond the speciesist ethic of the era of factory farming, of the use of animals as mere research tools, of whaling, seal hunting, kangaroo slaughter, and the destruction of wilderness. We must take the final step in expanding the circle of ethics. -”

“Driving a hybrid car could save about one ton of carbon-dioxide emissions per year but adopting a plant-based diet would save nearly one and a half tons over a comparable period.""If every American reduced chicken consumption by one meal per week, the carbon-dioxide savings would be equivalent to removing 500,000 cars form the road."In a given year, "the number of animals killed to satisfy American palates is 8.6 billion, or 29 animals per average American meat eater. The total number of animals killed on land and sea was approximately 80 billion, or 270 per American meat and fish eater - making the average number of animals consumed in one American lifetime 21,000.”

“If we took 75% of the world’s trashed rangeland, we could restore it from agriculture back to functioning prairies — with their animal cohorts — in under fifteen years. We could further sequester all of the carbon that has been released since the beginning of the industrial age. So I find that a hopeful thing because, frankly, we just have to get out of the way. Nature will do the work for us. This planet wants to be grassland and forest. It does not want to be an agricultural mono-crop.”

“CG Jung:Thoughts grow in me like a forest, populated by many different animals. But man is domineering in his thinking, and therefore he kills the pleasure of the forest and that of the wild animals. Man is violent in his desire, and he himself becomes a darker forest and a sickened forest animal. Just as I have freedom in the world, I also have freedom in my thoughts. Freedom is conditional.”
