生命原理与人口控制

Life principle and population control

平衡原理、关联原理、生命伦理是以生存原则为前提的三大生命原理。生物种群、生物量与环境容量必须保持平衡的平衡原理及平衡原理贯彻的必然性和破坏性，提供了人口控制的必然性；生物数量、体形（质量）、寿命以环境容量空—时限定为背景的相互关联，和人类作为一个“生态学悖论”的存在，表现了人口控制的紧迫性；而生命伦理，则体现了人口控制对人类和生物的道德性。

Obeying survival principle,equilibrium principle, association adaptation and life ethic are three important life principles.The equilibrium principle,which requiring groups and biomass to keep balance with environment capacity,and the necessity and the demolishment to carry out the equilibrium principle provide the need to control population.With the background of environment capacity's space-time restriction,the inter-association among biomass,shape(quality)and longevity,and the existing of human being, which exist as an'ecology contradiction',manifest the pressure to control population;Whereas,life ethic embodies morality for population control to human beings and biology.
