The whole field of neo-classical economics is based something close to mathematical fraud.

So many experts confused on the subject and saying otherwise makes clarity a scarce commodity.
Soon to be released research from the United Nations is expected to place species loss, a/k/a mass extinction, as an environmental threat equal to or greater than climate change. Industrial agriculture— vast expanses of monoculture crops managed with chemical fertilizers, herbicides and pesticides, will feature prominently as a cause. This plant agriculture supplies people with increasingly toxic and processed food and antibiotic and hormone dependent factory farms with animal feed. Together, these link the model of capitalist efficiency economists have been selling for the last two centuries to environmental crisis.
