I try to keep three reusable bags in my trunk and three more on a hook by my door  in my apartment. When I bring up groceries, I hang the empty bags on the hook  -  so if there are more than than three in either location - I bring back the difference  on my next trip.   If I  ever do need to take a disposable bag, I try to reuse it as much as possible.    And limiting it to three bags helps me be more mindful of my purchases or what I am bringing to an event. 

Yes it can and ultimately will  - It will require market driven buy-in and clean energy solutions to shift away from monoculture and centralized farming.
