I’m usually the last person to take this side of a discussion but I don’t see how feasible since:

  - the existence species regeneration does not imply the incentivize to regenerate and manage the vast majority of extinct species  
  - lack of gene samples for vast majority of species  
  - we don’t and are not very close to having a viable model for environment and species fitness so we can’t accurately model what specifies to regenerate  
  - new species populations have to be managed before and after initial release 
  - land and labor capital investment
