...1980s, Fernando Nottebohm of Rockefeller University brought new respect to the term birdbrain by demonstrating that the brain of an adult canary has the astonishing ability to regenerate new nerve cells at a rate of up to 20,000 a day. Other researchers reported similar regenerative ability in fish and reptiles, but there was still no evidence that evolution had passed on this ability to the human brain. Indeed, most neuroscientists wouldn't even entertain the possibility of new cell growth in the human brain on the grounds that any additional cells would disrupt the brain's complex wiring...
...just food but reward as well. But in the coming century, that will change. Much as we have awakened to the full economic and social costs of cigarettes, we will find we can no longer subsidize or ignore the costs of mass-producing cattle, poultry, pigs, sheep and fish to feed our growing population. These costs include hugely inefficient use of freshwater and land, heavy pollution from livestock feces, rising rates of heart disease and other degenerative illnesses, and spreading destruction of the forests on which much of our planet's life depends...
Unfortunately, this isn't just a matter of productive capacity. Mass production of meat has also become a staggering source of pollution. Maybe cow pies were once just a pastoral joke, but in recent years livestock waste has been implicated in massive fish kills and outbreaks of such diseases as pfiesteria, which causes memory loss, confusion and acute skin burning in people exposed to contaminated water. In the U.S., livestock now produce 130 times as much waste as people do. Just one hog farm in Utah, for example, produces more sewage than the city of Los Angeles. These megafarms...
