1 " Eating dinner with conservation biologists was like walking through a minefield of ethical decisions: grasslands have been overgrazed by steer raised for beef, and all cattle emit greenhouse gases though enteric fermentation; the poop from industrially raised chickens poisons the Chesapeake; the Amazon has been slashed and burned for soy--and don't even mention seafood. To this bunch of herpetologists, the sin of ordering shrimp lay in the bycatch--young fish, and especially sea turtles, caught in the nets and discarded, dead or dying. "

2 " It is hard for us to imagine now, but our earliest human ancestors who ventured out onto the grasslands of East Africa some six million years ago were remarkably weak and vulnerable creatures. They stood less than five feet tall. They walked upright and could run on their two legs, but nowhere near as fast as the swift predators on four legs that pursued them. They were skinny—their arms could not provide much defense. They had no claws or fangs or poison to resort to if under attack. To gather fruits, nuts, and insects, or to scavenge dead meat, they had to move out into the open savanna where they became easy prey to leopards or packs of hyenas. So weak and small in number, they might have easily become extinct.And yet within the space of a few million years (remarkably short on the time scale of evolution), these rather physically unimpressive ancestors of ours transformed themselves into the most formidable hunters on the planet. What could possibly account for such a miraculous turnaround? "

3 " When our earliest human ancestors left the trees and moved to the open grasslands of the savanna, they adopted an upright stance. Possessing already this powerful visual system, they could see far into the distance (giraffes and elephants might stand taller, but their eyes are on the sides, giving them instead panoramic vision). This allowed them to spot dangerous predators far away on the horizon and detect their movements even in twilight. Given a few seconds or minutes, they could plot a safe retreat. At the same time, if they focused on what was nearest at hand, they could identify all kinds of important details in their environment—footprints and signs of passing predators, or the colors and shapes of rocks that they could pick up and perhaps use as tools.

4 " Since its sudden birth the city had expanded, swallowing up acre upon acre of the surrounding grasslands and drawing thousands into its domain. Hardly built on the most advantageous ground, miles from the open waters, decades from the mines at the mountain summits, it yet remained the only settlement of note on the isle. This sprawling mass of a city, once a compact kingdom, was now the keystone of the Castilian Empire. "
