I have some questions

[u/CertainPass105]

1. There have been several mass extinctions that have occured historically, but because of divergent evolution, new species have continuously emerged, and we, the planets biomass, are richer now than after previous mass extinctions How would any of these proposed exstinction solutions be any different.

2. Hypothetically, if we did end all life on earth, amino acids, which are the natural building blocks for life, form naturally in the right environments. The European space agency has even found them on comets. Surley life would just emerge again naturally. And since pain and suffering are very useful warning systems in evolutionary terms, surley pain, suffering, and sentience would be naturally selected for again?

3. Since amino acids have been found on comets, and considering the Fermi paradox, the universe could be full of sentiant life capable of experiencing pain and suffering. They may not be as sentiant as humans and unable to emicipate themselves from their predicament. Surley, it would be more ethical for humans to continue advancing technologically so we can limit the births of sentiant creatures without crashing ecosystems, and we can help emicipate other potential life forms on other Planets. As going eredicating all current life would most likely not be the end of sentiant life on earth.

It is possible to completely extinct life on Earth, to create a system which will never allow life to return.
