my personal,only,take is that i have no desire to see big cats,bears,sharks,orcas,barracuda,foxes,gators wiped out. i think the presence of carnivores is something that adds to the planet being a good place to live. i will say that feral cats,dogs and coyotes are a different subject. i am not a rancher,chicken worker or stock man so i understand there are other points of view. most large carnivores are probably doomed anyway.
i have seen the slaughter of sharks and it is just a sick and disgusting activity . this often comes from commercial fisherman who in my experience in FL are essentially criminal exploiters of a resource. basically corrupt gov supported economic poaching. i'd make it illegal planet wide if i had the power. of course,that would demand rational agricultural and live stock management. that will never happen.
this genetic work is fascinating but very scary. shows the ability to advance the singularity in new ways. i fear the tech will be used in ways that sci fi lit and movies have forecast many times
