There are a number of reasons that people are getting involved in hunting, women and youth in particular. Yes, you're quite right that part of it is because of family. Hunting and fishing are family activities in many areas, and certainly if the father or husband hunts, it's more likely that the other family members will also become involved.
There is also of course the whole organic food movement that's going on, this back-to the-land table movement for clean, fresh, unspoiled food. It's really a groundswell out there. Harvesting wildlife is about as close to the source as you can get without contaminants, without processing from industry, etc.
