* Creating life is always a good thing.
* Golden eagles are becoming extinct, freezing the sperm and using them when there is a good environment can help save the species.
* The golden eagles are not the only animals that this benefitial technique can apply to, it has a knock-on affect on other species.
* This is 'playing God', we are meddling with nature.
* We don't know any potential problems with frozen sperm. They might cause unhealthy eagles.
* There may be unpredictable long-term consequences.
* The story of Frankenstein's monster where a human created being turns into a tyrannical killer should warn us of the dangers of scientific arrogance!
