Before I got into the fitness industry I was a butcher for 10 years, and even in that short time I was gathering from people that everyone was slowly buying less beef because of the quality, but the ones who continued went for grass fed, organic, free range, etc.

I think "meat" will always be a dominant thing especially in the US but it will slowly switch from QUANTITY to QUALITY over the next 10-15 years. Less people will eat it because it will become more expensive as people realize quality sells better at higher prices then crappy cuts for cheap.
