人类为了缓解能源、粮食、环境、资源等正日益困扰人类的几大问题,使人类有一个更好的生存环境和生存空间,有意识地在实行计划生育。动物虽然没有意识行为,但早在人类开始计划生育的数千年前,许许多多的动物已经计划生育啦!它们自觉地实行了我国当今正实行少生优生”措施。 In order to alleviate the major problems that are increasingly besetting humanity, such as energy, food, environment, and resources, human beings have a better living environment and living space for human beings and consciously implement family planning. Although animals do not have conscious behavior, as many thousands of years ago as humans began to plan for birth, many animals have already planned for birth! They consciously carried out the measures that our country is currently implementing with fewer births.
