Document Summary
Population growth at the centre of environmental degradation. The growth of livestock population has grown faster than human population. There are many more animals slaughtered on earth then there exists (um, how does that make any sense!?!?!?) Not just meat consumption, but also oilseed and arable land disparities between the world"s richest and poorest countries. Animal feed: 30% of world"s arable land. 90% world cropland in maize, wheat, rice, soy, sugar, palm oil, and cotton. Relatively closed-loop cycles of biological and physical materials, animals, and photosynthesized energy. Mechanization to industrialization: enables long-distance movements of input and outputs. Standardization/biological simplification to agriculture as through flow process contingent on external inputs and outputs. Mechanization to monocultures (soil mining) to (disarticulation of livestock from land) factory farms and feedback. Countries most affected by rising food prices are also the poorest and most agrarian countries. Who: obesity a global pandemic (about 1. 3 billion)
