...feed, given its present technology. Photos by earth satellites reveal that the world's most productive land is already cultivated, convenient water sources already tapped and nearly all grazing capacity already in use. Marine biologists worry that the sea, once regarded as a nearly unlimited source of cheap protein, has been overfished. To bring marginal farmland into use round the world would require a massive investment beyond the means of the underdeveloped nations and probably beyond the generosity or administrative cooperation of the developed nations...
...treadmill. Although the African nations in the hunger belt have boosted their food production 22% since the early 1960s, per capita consumption has actually fallen 5% because of increased population. By contrast, Americans during the same period went from eating 118% of their basic energy requirements (in terms of protein) to 123%, Soviets and East Europeans from 116% to 126%, and China from...
...third its normal size and has actually separated into four parts. The fishing village of Bol, once a lakeside settlement, today looks out on a vast wasteland of parched scrubgrass stretching 18 miles to the water. The lake's fish catch has been halved, creating a protein deficiency that aggravates an already short supply of grains. In northern Chad, nomads are eating boiled tree bark and roots...
Spinal discs, cushionlike pads that separate the vertebrae, are composed of tough, cartilaginous fibers and filled with water and a protein called "ground substance." When surrounding tissues tear, the disc bulges, or slips, out of its normal position, causing pain in the back and, when it pushes against the sciatic nerve, in the legs...
...receiving area where, says Farr, "we can dip, brand, castrate and vaccinate them in 30 seconds." Then the animals get their first taste of eating feed-lot-style. The first meal is alfalfa hay, which smells something like familiar range grass, mixed with a little bit of high-protein feed. Their diet is made "hotter" by adding larger proportions of corn, malt, sour-smelling silage, beet pulp, minerals and antibiotics. The animal's metabolism is soon racing so hard to digest the rich fare that if its diet is drastically changed, the steer will sicken and could...
