I don't think there needs to be more awareness. We are talking about a SELECT few pets that will outlive people. Turtles, Tortoises, and POSSIBLY ball pythons although not all live until they are 45.
I mean to assume people shouldn't get those pets because they might outlive them doesnt make sense. What about someone with a special needs child born when they are older? Should they adopt the child out just to make sure someone will be around when they pass on? No. You just do your best until your time comes and hopefully have a back up plan.
