Here, did you want some background ideas for you science fiction?  In-universe, violating some of these could be considered morally unthinkable.

• Abortion is banned, but everyone is born naturally sterile unless they get a procedure to allow them to have children.
• Meat-eating from animals is banned except for a few “traditional” cultures.  This actually includes the Amish and a few "historical,” pasture-based farms.  Everyone just eats engineered meat grown in tubes instead. 
• Similarly, aside from a handful of traditional farms, the vast majority of milk products are created using tissue engineering and modified bacteria due to perceived animal consent issues.
• Predator-prey relationships still exist in nature, but prey animals have been genetically modified to lose awareness after sustaining a sufficient level of injury.
• Prison is considered cruel and inhumane.  Instead, convicted criminals are fitted with internal cybernetic restraints that are monitored by AIs and physically prevent them from engaging in certain actions.  (Alternatively, it weakens, dampens, and delays their motor actions.)
• Alternatively, prison is considered cruel and inhumane, instead, convicted criminals are subjected to a regime of corporal punishment, but otherwise are allowed to roam a small, isolated town. 
• It is unthinkable that someone would choose for their child to be monosexual instead of bi- or pansexual.  It has not yet been classified as child abuse.
• People are almost immortal.  It turns out population explosion isn’t a risk because wanting to have lots of kids is not genetic, but primarily social.  Thus, it’s only considered a weird thing some women do.  To meet population replacement goals, most children are grown in vats and raised by the state.

Moral progress, you guys.
