With around one billion people living in high-income countries, it would thus cost just $2 to $3 per person per year in the developed world to fund an effort that could save more than one million children annually. When child mortality is reduced, poor families choose to have fewer children, because they are more confident that their children will survive to adulthood.
生活在高收入国家的人口大约在10亿左右，也就是说发达国家每人每年只需捐出2到3美元就可以支持每年拯救百万儿童的花销。如果儿童死亡率能够降低，那些贫困家庭就会选择少生孩子，因为他们确信自己的孩子能够活到成年。令人感到不可思议的是，拯救儿童的生命却会变成贫困国家人口迅速增长的解决之道。
