The embryo space colonization (ESC) concept is an interesting, very rational and quite effective way to guarantee the survival of the human species, as long as the technology is achieved and no unforeseen complications arise during even many millions of years journey to an exoplanet. Despite these formal advantages of the concept, this paper points to a number of arguments against its validity. These arguments revolve around two issues. One is to point out that while the concept of saving the Homo sapiens species is noble and should be supported, the way of saving humanity envisioned by the ESC departs from what should be understood by the concept of saving humanity through space colonization. The second issue is to draw attention to the ethical controversies that make this concept perhaps unsuitable for implementation at all. At least some of these objections do not address the concept of saving humanity by sending adult living persons on space missions.

人类应该为了生存而殖民太空，而不是胚胎太空殖民

胚胎空间殖民 (ESC) 概念是一种有趣、非常合理且非常有效的方式来保证人类物种的生存，只要技术得到实现，并且在数百万年的系外行星旅程中不会出现不可预见的并发症。尽管该概念具有这些形式上的优势，但本文指出了一些反对其有效性的论据。这些论点围绕两个问题。一是要指出，虽然节约的概念智人物种是崇高的，应该得到支持，ESC所设想的拯救人类的方式与通过太空殖民拯救人类的概念应该理解的不同。第二个问题是提请注意使这一概念可能根本不适合实施的伦理争议。至少这些反对意见中的一些没有解决通过派遣成年活人执行太空任务来拯救人类的概念。
