Population and the Environment: A Parable of Firewood and Other Tales
分析人口与环境的关系，重点探讨环境退化和自然资源消耗如何导致人口压力，并指出在缺乏社会约束时，父母对子女的利他行为会加剧出生率上升，使得人口与环境稳定均衡的可能性非常有限。
The author analyzes the relationship between population and the environment, with a focus on "the role which environmental degradation and natural resources depletion may play in producing the...population pressure which lies behind such degradation and depletion especially in developing countries.... The principal conclusion of this analysis is that the possibilities for a stable equilibrium between human population and its environment are quite limited....I show that parental altruism toward their children can only make matters worse, if socially unchecked, by leading to an increase of the birthrate in every environmental state in comparison with that which would occur in its absence."
