But many years ago, we took the worst land in Zimbabwe, where I offered a £5 note in a hundred-mile drive if somebody could find one grass in a hundred-mile drive, and on that, we trebled the stocking rate, the number of animals, in the first year with no feeding, just by the movement, mimicking nature, and using a sigmoid curve, that principle.
很多年前，我们得到一块津巴布韦最差的土地， 当时我出5英镑打赌 没人能在一百英里的 驾程范围内找到一根草 在一百英里的驾程范围， 我们把动物的数量增加了三倍， 第一年没有提供食物， 只靠迁徙，模仿自然， 使用S型曲线的原理。
